It had head gaskets done to It had 19 00:00:49,280 --> 00:00:51,880 Speaker 4: a bunch of other diagnostic repairs performed to it. It 20 00:00:51,920 --> 00:00:55,120 Speaker 4: had a pile of other work that all, whether they 21 00:00:55,160 --> 00:00:57,680 Speaker 4: were part of the attempt to resolve the problem for 22 00:00:57,760 --> 00:01:01,320 Speaker 4: this poor little Corvette or as just other work that 23 00:01:01,400 --> 00:01:04,920 Speaker 4: it needed, it just had been through the mill when 24 00:01:04,920 --> 00:01:07,080 Speaker 4: it showed up at the shop. I you know, I 25 00:01:07,120 --> 00:01:09,039 Speaker 4: told the customer, I said, ted, let's go for a ride. 26 00:01:09,120 --> 00:01:11,280 Speaker 4: Let's let's let me see what this is doing. Up 27 00:01:11,280 --> 00:01:13,479 Speaker 4: close and personal, because it was one of those cars 28 00:01:13,520 --> 00:01:16,080 Speaker 4: that I could tell by listening to him at the 29 00:01:16,080 --> 00:01:18,640 Speaker 4: counter and by reading some of the things that had 30 00:01:18,640 --> 00:01:20,200 Speaker 4: been done to it. It had been kind of picked 31 00:01:20,200 --> 00:01:22,720 Speaker 4: through like a chicken at a barbecue. And I said, 32 00:01:22,760 --> 00:01:25,920 Speaker 4: you know what, I want to experience this with him. 33 00:01:26,360 --> 00:01:29,319 Speaker 4: So we went for a road test and the car 34 00:01:29,440 --> 00:01:31,480 Speaker 4: ran terrible. It had a real rough idol. It was 35 00:01:31,560 --> 00:01:34,360 Speaker 4: bucking and missing, and it lunged at idle. 36 00:01:34,400 --> 00:01:34,960 Speaker 2: It did match. 37 00:01:35,080 --> 00:01:37,160 Speaker 4: It lunged as speed and it idle, and it did 38 00:01:37,319 --> 00:01:41,399 Speaker 4: match his description. It just ran poorly through every test in. 39 00:01:41,400 --> 00:01:42,000 Speaker 2: The book at it. 40 00:01:42,120 --> 00:01:45,640 Speaker 4: We went through the diagnostic regimen. It took the crew 41 00:01:45,880 --> 00:01:49,480 Speaker 4: right through every diagnostic procedure that we pretty much known, 42 00:01:49,520 --> 00:01:51,640 Speaker 4: and we got about three quarters of the way through 43 00:01:52,400 --> 00:01:55,840 Speaker 4: and we were down to, gee, what's going on with 44 00:01:55,960 --> 00:01:59,280 Speaker 4: injectors because these are the multec injectors, and GM had 45 00:01:59,320 --> 00:02:02,160 Speaker 4: some problems with these, had a lot of problems with 46 00:02:02,200 --> 00:02:04,680 Speaker 4: these in the eighties and into the nineties, and you know, 47 00:02:04,720 --> 00:02:06,880 Speaker 4: we started to take a real hard look at them. 48 00:02:06,880 --> 00:02:09,320 Speaker 4: And when I say we diagnosed, we went through codes 49 00:02:09,320 --> 00:02:13,200 Speaker 4: and visual and data stream analysis. We scoped ignition, we 50 00:02:13,560 --> 00:02:16,560 Speaker 4: went through engine vacuum. We went through vacuum leaks, we 51 00:02:16,639 --> 00:02:20,160 Speaker 4: propane enrichment, we did smoke tests, we went through the gamut, 52 00:02:20,200 --> 00:02:23,200 Speaker 4: we went through PCM power and grounds. Can't leave a 53 00:02:23,240 --> 00:02:27,440 Speaker 4: stone unturned. Well, we got down to the injectors, and 54 00:02:28,040 --> 00:02:31,280 Speaker 4: sure enough, two of the injectors right off the bat 55 00:02:31,360 --> 00:02:34,240 Speaker 4: tested bed. They didn't scope well. You could see that 56 00:02:34,280 --> 00:02:36,399 Speaker 4: when we ramped them. We looked at current and draw 57 00:02:36,440 --> 00:02:38,720 Speaker 4: that they were all over the place. They weren't anywhere 58 00:02:38,720 --> 00:02:42,600 Speaker 4: close to specification. We went through all eight. Five of 59 00:02:42,639 --> 00:02:45,560 Speaker 4: the eight injectors were bad. They owned bed and they 60 00:02:45,639 --> 00:02:49,720 Speaker 4: scoped bed. All right, now we have something to go on. 61 00:02:50,200 --> 00:02:51,920 Speaker 4: Don't know if this is the end of it. Don't 62 00:02:51,919 --> 00:02:54,919 Speaker 4: know if this is the final draw. I told the customer, 63 00:02:54,960 --> 00:02:57,480 Speaker 4: but you've got to start here. You've got to chase 64 00:02:57,560 --> 00:03:01,880 Speaker 4: what's known. Bad said, go ahead, after swallowing hard when 65 00:03:01,880 --> 00:03:04,200 Speaker 4: I told him the price tag about two grand to 66 00:03:04,240 --> 00:03:07,359 Speaker 4: put injectors in this vehicle, because they weren't cheap in 67 00:03:07,400 --> 00:03:09,320 Speaker 4: the very labor intensive operation. 68 00:03:10,240 --> 00:03:12,639 Speaker 2: And we went ahead and ordered injectors. 69 00:03:12,720 --> 00:03:15,079 Speaker 4: They showed up, and I'm happy to tell you that 70 00:03:15,639 --> 00:03:18,080 Speaker 4: it may have been expensive, and it was an expensive 71 00:03:18,120 --> 00:03:20,640 Speaker 4: diagnosis and a tedious diagnosis. 72 00:03:20,960 --> 00:03:23,160 Speaker 2: It did end up fixing the car. 73 00:03:23,320 --> 00:03:26,240 Speaker 4: The car runs like an eighty nine Corvette should, as 74 00:03:26,320 --> 00:03:27,919 Speaker 4: Gus said when I took him out for a ride 75 00:03:28,000 --> 00:03:30,720 Speaker 4: late Friday, he said, Wow, this runs almost as good 76 00:03:30,720 --> 00:03:31,400 Speaker 4: as my accurate. 77 00:03:31,400 --> 00:03:33,000 Speaker 2: And I looked at him and I said, Gus, it 78 00:03:33,080 --> 00:03:34,720 Speaker 2: runs a whole lot better than your accurate. 79 00:03:34,720 --> 00:03:36,640 Speaker 4: I think I've got to think you out for rides 80 00:03:36,640 --> 00:03:41,000 Speaker 4: and more Corvettes. But bottom line, it's going to be 81 00:03:41,040 --> 00:03:44,280 Speaker 4: expensive to diagnose a problem, and it might be more 82 00:03:44,320 --> 00:03:47,280 Speaker 4: than you want to spend, but getting a diagnosis, and 83 00:03:47,320 --> 00:03:50,920 Speaker 4: that's the point of this, because this little red Corvette 84 00:03:51,560 --> 00:03:55,920 Speaker 4: was repaired after a diagnosis. And you've got to ask yourself, 85 00:03:56,120 --> 00:03:58,600 Speaker 4: do you want to go for the expensive diagnosis or 86 00:03:58,600 --> 00:04:01,080 Speaker 4: do you want to go for the expensive unecessary work 87 00:04:01,080 --> 00:04:03,720 Speaker 4: that gets done as part of a diagnosis and ended 88 00:04:03,760 --> 00:04:05,440 Speaker 4: up getting it diagnosed to get it repaired in the 89 00:04:05,520 --> 00:04:06,080 Speaker 4: first place. 90 00:04:06,360 --> 00:04:08,160 Speaker 2: So where do you want to start? At the beginning 91 00:04:08,240 --> 00:04:08,680 Speaker 2: or the end? 92 00:04:09,040 --> 00:04:11,720 Speaker 4: If you want to repair the difficult, you have to 93 00:04:11,840 --> 00:04:13,680 Speaker 4: diagnose from the beginning. 94 00:04:14,160 --> 00:04:15,240 Speaker 2: Hello, and welcome to the car. 95 00:04:15,280 --> 00:04:17,280 Speaker 4: Doctor Ron and Aenian here right now, we've got a 96 00:04:17,320 --> 00:04:19,039 Speaker 4: bunch of things going on here in the garage. Let's 97 00:04:19,080 --> 00:04:21,680 Speaker 4: kick open the doors and get over to Randy Appleton, 98 00:04:21,720 --> 00:04:25,240 Speaker 4: Wisconsin with an six Chevy Trailblazer. Hey, Randy, what's doing 99 00:04:25,320 --> 00:04:27,039 Speaker 4: up there in Wisconsin. How's the weather today? 100 00:04:27,440 --> 00:04:29,039 Speaker 5: It's a bit sunny and a bit breezy. 101 00:04:29,080 --> 00:04:30,960 Speaker 2: It sounds like New York. What's going on? 102 00:04:31,279 --> 00:04:33,720 Speaker 5: Well? I have a two thousand and six Chevy trail 103 00:04:33,720 --> 00:04:36,360 Speaker 5: Blazer and I got twenty one thousand miles on it. 104 00:04:36,560 --> 00:04:40,280 Speaker 5: And I talked to the local dealer in town, the 105 00:04:40,400 --> 00:04:43,000 Speaker 5: Chevy dealer, and he told me what it does is 106 00:04:43,000 --> 00:04:47,840 Speaker 5: when the engine is cold, it makes a metallic chatter, 107 00:04:48,720 --> 00:04:51,200 Speaker 5: and then when as the engine warms up, it goes away. 108 00:04:51,200 --> 00:04:54,400 Speaker 5: And he said that's typical. He has a similar vehicle 109 00:04:55,200 --> 00:04:58,920 Speaker 5: and he explained it. In five GM went to a 110 00:04:59,000 --> 00:05:03,160 Speaker 5: shorter piston scre trying to get improved fuel economy, and 111 00:05:03,200 --> 00:05:06,320 Speaker 5: that's just the nature of the beast, correct. I guess 112 00:05:06,440 --> 00:05:10,360 Speaker 5: my question is will I get premature where because of that? 113 00:05:11,040 --> 00:05:13,320 Speaker 5: And if so, will GM stand behind it? 114 00:05:14,760 --> 00:05:17,479 Speaker 4: I think the official position is that no, you won't 115 00:05:17,520 --> 00:05:20,359 Speaker 4: get premature where, and it's covered under the extent of 116 00:05:20,400 --> 00:05:24,560 Speaker 4: their warranty. Now, So saying that I will go backwards 117 00:05:24,640 --> 00:05:27,320 Speaker 4: to about model year two thousand and two thousand and one, 118 00:05:27,839 --> 00:05:30,760 Speaker 4: when GM had other piston slap issues and there was 119 00:05:30,800 --> 00:05:32,599 Speaker 4: a website up at one time. I think it was 120 00:05:32,680 --> 00:05:36,400 Speaker 4: GM pistonslap dot com or pistonslap dot. 121 00:05:36,200 --> 00:05:37,240 Speaker 2: Com, I forget what it was. 122 00:05:37,360 --> 00:05:39,360 Speaker 4: We played it on air a couple of years back, 123 00:05:39,640 --> 00:05:41,479 Speaker 4: where you can actually go to the website, and this 124 00:05:41,520 --> 00:05:44,279 Speaker 4: guy was so furious at General Motors. He actually came 125 00:05:44,400 --> 00:05:47,400 Speaker 4: up with different noises that the different engines make and 126 00:05:47,440 --> 00:05:51,479 Speaker 4: he plays him in MP three format. It's it's the 127 00:05:51,600 --> 00:05:55,640 Speaker 4: stories that I've seen and the vehicles that i've you know, 128 00:05:55,760 --> 00:05:58,800 Speaker 4: had the ability or the time and the opportunity to diagnose, 129 00:05:59,320 --> 00:06:04,040 Speaker 4: are not showing signs of premature where now you know, 130 00:06:04,080 --> 00:06:06,839 Speaker 4: in my corner of the world, that doesn't mean that 131 00:06:06,880 --> 00:06:08,720 Speaker 4: in Wisconsin it's going to be different. But I can 132 00:06:08,720 --> 00:06:11,040 Speaker 4: tell you from a pattern failure and a track record. 133 00:06:11,360 --> 00:06:13,479 Speaker 4: The answer to the first question is no, you should 134 00:06:13,560 --> 00:06:18,159 Speaker 4: not experience premature. Where can I guarantee you that absolutely not? 135 00:06:19,040 --> 00:06:20,680 Speaker 4: And I know that's not what you're looking for, but 136 00:06:20,720 --> 00:06:23,080 Speaker 4: that's the answer to the first question. The second question 137 00:06:23,160 --> 00:06:24,960 Speaker 4: and why I brought up the fact that it happened 138 00:06:25,000 --> 00:06:27,719 Speaker 4: back in two thousand and two thousand and one, GM 139 00:06:27,920 --> 00:06:30,960 Speaker 4: at that time was extending the warranty on the vehicles 140 00:06:31,000 --> 00:06:34,200 Speaker 4: that had problems that you know, for whatever reason, whether 141 00:06:34,240 --> 00:06:37,440 Speaker 4: it was noise or were issues that if it was 142 00:06:37,480 --> 00:06:40,320 Speaker 4: in doubt, they gave the leeway to the customer. I 143 00:06:40,400 --> 00:06:43,000 Speaker 4: don't know that that extends to the newer models. And 144 00:06:43,040 --> 00:06:44,960 Speaker 4: as a matter of fact, you're the first I'm hearing 145 00:06:45,000 --> 00:06:47,600 Speaker 4: about that the newer ones are having this particular problem, 146 00:06:47,680 --> 00:06:50,200 Speaker 4: because I thought after three h four they were pretty much. 147 00:06:50,080 --> 00:06:53,359 Speaker 5: Gone, oh okay, because, like I say, they said that 148 00:06:53,560 --> 00:06:57,599 Speaker 5: was you know, inherent inherent in the vehicle, and right. 149 00:06:57,640 --> 00:06:59,240 Speaker 4: Now I knew, well, I knew that they I knew 150 00:06:59,279 --> 00:07:02,119 Speaker 4: that they played with diston skirt design. But I haven't 151 00:07:02,120 --> 00:07:04,360 Speaker 4: heard of any complaints on newer ones. After row three 152 00:07:04,480 --> 00:07:06,960 Speaker 4: oh four, I thought it was pretty much over. But 153 00:07:07,000 --> 00:07:08,560 Speaker 4: it's something I'll have to go back and research. 154 00:07:08,560 --> 00:07:12,200 Speaker 5: And yeah, four he even told me. As winter progressed, 155 00:07:12,480 --> 00:07:14,720 Speaker 5: you know, it'll get worse because the colder it is, 156 00:07:15,320 --> 00:07:16,800 Speaker 5: the more it's going to do it, and of course 157 00:07:16,920 --> 00:07:19,520 Speaker 5: the longer it'll do it, because it'll take that much 158 00:07:19,560 --> 00:07:20,960 Speaker 5: longer for the engine to warm up. 159 00:07:21,120 --> 00:07:24,160 Speaker 2: Right, you probably experience it for the first two minutes. 160 00:07:24,720 --> 00:07:25,400 Speaker 5: Yeah, or so. 161 00:07:25,640 --> 00:07:29,360 Speaker 4: You're you're using their recommended way oil, yes, five thirty 162 00:07:29,400 --> 00:07:30,120 Speaker 4: or five twenty. 163 00:07:30,240 --> 00:07:32,400 Speaker 5: Yeah. I took it to the Chevy dealer to do 164 00:07:32,440 --> 00:07:34,160 Speaker 5: the oil change, so I'm assuming they put in the 165 00:07:34,200 --> 00:07:35,080 Speaker 5: correct stuff. Right. 166 00:07:35,160 --> 00:07:37,400 Speaker 2: Have you contacted General Motors directly at all? 167 00:07:37,600 --> 00:07:37,680 Speaker 3: No? 168 00:07:37,760 --> 00:07:38,200 Speaker 5: I haven't. 169 00:07:38,360 --> 00:07:40,440 Speaker 4: You may want to just get a complaint on register 170 00:07:40,560 --> 00:07:44,360 Speaker 4: with them, okay, just so that if information changes, they'll 171 00:07:44,360 --> 00:07:47,960 Speaker 4: contact you and let you know status. But it wouldn't hurt. 172 00:07:47,960 --> 00:07:49,920 Speaker 4: But it's just, unfortunately, something you've got to stay on 173 00:07:49,960 --> 00:07:51,640 Speaker 4: top of. I mean, listen, I own it. I own 174 00:07:51,680 --> 00:07:55,120 Speaker 4: an four Chevy Suburban. I really have no I really 175 00:07:55,120 --> 00:07:58,280 Speaker 4: have no noise. Now that's before five. Like I said, 176 00:07:58,520 --> 00:08:00,720 Speaker 4: after three, I thought the problem was gone. I'm kind 177 00:08:00,720 --> 00:08:03,720 Speaker 4: of disappointed to hear that they that they're creating noise 178 00:08:03,760 --> 00:08:06,240 Speaker 4: with their piston skirt design change, because I knew they 179 00:08:06,360 --> 00:08:08,120 Speaker 4: changed the skirt, but I had not heard of the 180 00:08:08,160 --> 00:08:09,480 Speaker 4: particular noise issue. 181 00:08:09,880 --> 00:08:12,560 Speaker 5: Okay, all right, One other quick question. About a month 182 00:08:12,680 --> 00:08:15,240 Speaker 5: or so back on your program, you mentioned about Toyotas 183 00:08:15,280 --> 00:08:17,000 Speaker 5: with an oil gumming. 184 00:08:16,760 --> 00:08:19,960 Speaker 1: Issue sludge issues on the V six is okay? 185 00:08:19,960 --> 00:08:22,600 Speaker 5: Would that be inherent to like a Toyota. 186 00:08:22,320 --> 00:08:24,280 Speaker 2: To Siena, what engines in it? 187 00:08:24,720 --> 00:08:28,080 Speaker 5: The three point three say that again, the three point. 188 00:08:27,960 --> 00:08:31,320 Speaker 4: Three, Yeah, they they all had the issue. Now in 189 00:08:31,920 --> 00:08:35,240 Speaker 4: some of the later models, what your Sienna or five. 190 00:08:35,840 --> 00:08:38,920 Speaker 4: Supposedly by then the cylinder head was redesigned so that 191 00:08:38,960 --> 00:08:41,360 Speaker 4: the exhaust valve didn't have the angle problem that it 192 00:08:41,440 --> 00:08:45,120 Speaker 4: was creating the sludge. But you know, the real question 193 00:08:45,160 --> 00:08:46,800 Speaker 4: here is how often you changing the oil. 194 00:08:47,600 --> 00:08:51,280 Speaker 5: We're following what the dealer recommended that every five thousand. 195 00:08:51,040 --> 00:08:53,520 Speaker 4: A month, right, tried doing it every three Okay, Yeah, 196 00:08:53,559 --> 00:08:55,520 Speaker 4: if you stay with every three, I think you're going 197 00:08:55,559 --> 00:08:58,600 Speaker 4: to come out miles ahead. And you know, the biggest 198 00:08:58,600 --> 00:09:02,000 Speaker 4: issue still comes back to changing the oil every three months, 199 00:09:02,040 --> 00:09:05,240 Speaker 4: every three thousand miles. Not to be cliche and sound 200 00:09:05,320 --> 00:09:06,800 Speaker 4: like I do when I'm when I'm doing the TV 201 00:09:06,880 --> 00:09:11,199 Speaker 4: commercial and spot it really is true. It's the best 202 00:09:11,200 --> 00:09:14,960 Speaker 4: defense against sludge issues and premature engineer. 203 00:09:14,880 --> 00:09:16,760 Speaker 5: Sounds great, all right, thank you for help. 204 00:09:16,760 --> 00:09:19,600 Speaker 4: You're very welcome, Randy. You take good character. I'm here 205 00:09:20,000 --> 00:09:21,960 Speaker 4: to answer your car questions. Pick up the phone, give 206 00:09:22,000 --> 00:09:24,280 Speaker 4: me a call, let's talk about it. We'll be back right. 207 00:09:24,120 --> 00:09:24,559 Speaker 2: After this. 208 00:09:58,640 --> 00:10:00,600 Speaker 4: Welcome back, Ronn and Ady in the car doctor at 209 00:10:00,600 --> 00:10:02,360 Speaker 4: your service. So let's go over and talk to Terry 210 00:10:02,360 --> 00:10:06,000 Speaker 4: Manahawk in New Jersey. Terry, welcome, Hello run Yes, sir. 211 00:10:07,040 --> 00:10:09,600 Speaker 3: I heard an earlier caller that called you with an 212 00:10:09,600 --> 00:10:13,760 Speaker 3: O four Grand Marquis okay, startup noise. I also called 213 00:10:13,800 --> 00:10:18,000 Speaker 3: you myself months earlier with a similar problem. I actually 214 00:10:18,080 --> 00:10:22,400 Speaker 3: had two separate noises with two separate causes. They gave 215 00:10:22,440 --> 00:10:25,679 Speaker 3: me noise a startup okay. One was resolved by using 216 00:10:25,679 --> 00:10:28,679 Speaker 3: a motorcraft or equivalent oil filter. 217 00:10:28,640 --> 00:10:30,000 Speaker 2: Right because of the drain back valve. 218 00:10:30,160 --> 00:10:32,080 Speaker 3: Right, that was addressed in the owner's manual. 219 00:10:34,559 --> 00:10:36,400 Speaker 4: And that's true, I should point out, Terry, that's true 220 00:10:36,400 --> 00:10:38,719 Speaker 4: on just about any car on the road today. If 221 00:10:38,760 --> 00:10:41,120 Speaker 4: you're using a cheap oil filter that doesn't have proper 222 00:10:41,200 --> 00:10:45,000 Speaker 4: drain back valve control. Okay, you'll you'll experience that problem. 223 00:10:45,040 --> 00:10:47,560 Speaker 4: That's not something specific just to a Ford product. But 224 00:10:47,800 --> 00:10:49,000 Speaker 4: go ahead, I'm sorry to interrupted. 225 00:10:49,040 --> 00:10:52,000 Speaker 3: Okay, Well, the second noise was sounded like a timing 226 00:10:52,080 --> 00:10:59,680 Speaker 3: chain noise, all right, And that was intermittent. It wasn't 227 00:10:59,679 --> 00:11:04,360 Speaker 3: it all? Only curd a startup. And I actually had 228 00:11:04,360 --> 00:11:06,520 Speaker 3: a videotape that so I could take it to the 229 00:11:06,559 --> 00:11:09,479 Speaker 3: dealer and played for them because I couldn't reproduce. 230 00:11:09,120 --> 00:11:12,880 Speaker 2: A noise, Okay, all the creative way to do it. 231 00:11:12,920 --> 00:11:13,480 Speaker 2: I like that. 232 00:11:13,960 --> 00:11:16,160 Speaker 3: Well, if I hadn't done that, they wouldn't have been 233 00:11:16,160 --> 00:11:17,400 Speaker 3: able to reproduce the noise. 234 00:11:17,679 --> 00:11:17,920 Speaker 2: Right. 235 00:11:18,520 --> 00:11:21,040 Speaker 3: The service manager heard it, and he agreed it was 236 00:11:21,040 --> 00:11:24,120 Speaker 3: a timing chain noise, all right. They kept the car 237 00:11:24,200 --> 00:11:26,360 Speaker 3: until they found out what the problem was. They had 238 00:11:26,360 --> 00:11:29,319 Speaker 3: it about a week. It was outside of warranty. You 239 00:11:29,400 --> 00:11:32,760 Speaker 3: had fifty thousand miles on it, but Ford worked with 240 00:11:32,840 --> 00:11:36,040 Speaker 3: me and they didn't charge me full price. As it 241 00:11:36,080 --> 00:11:40,560 Speaker 3: turned out, it was a timing chain tensioner. Now, this 242 00:11:40,600 --> 00:11:42,760 Speaker 3: guy explained it to me that it was leaking down 243 00:11:44,280 --> 00:11:47,439 Speaker 3: through his seal. He said there was a seal, a 244 00:11:47,520 --> 00:11:50,320 Speaker 3: rubber seal where met the block. They had a tear 245 00:11:50,360 --> 00:11:53,720 Speaker 3: in it, all right. And it appears to me that 246 00:11:53,720 --> 00:11:57,560 Speaker 3: that's not the case because I looked at another tension 247 00:11:57,559 --> 00:11:59,120 Speaker 3: I came off a motor that was laying on the 248 00:11:59,160 --> 00:12:02,080 Speaker 3: ground from my I picked it up and pressed on 249 00:12:02,120 --> 00:12:05,880 Speaker 3: the plunger that it creates at tension against the guides, right, 250 00:12:06,280 --> 00:12:08,040 Speaker 3: and I still had pressure and it just laying on 251 00:12:08,040 --> 00:12:09,800 Speaker 3: the ground by itself, not bolt. 252 00:12:09,520 --> 00:12:12,640 Speaker 2: At anything exact same tension or from your engine. 253 00:12:13,000 --> 00:12:15,760 Speaker 3: No, No, it's from a five to four point six 254 00:12:15,840 --> 00:12:18,520 Speaker 3: out of a ninety eight Mustang GT. 255 00:12:19,400 --> 00:12:21,720 Speaker 2: Okay, it could be a different design tensioner. 256 00:12:21,800 --> 00:12:23,960 Speaker 3: Well, I suppose that's possible. But I've been told by 257 00:12:24,000 --> 00:12:27,920 Speaker 3: the people that the seal is internal and the tensioner. 258 00:12:28,000 --> 00:12:30,800 Speaker 2: And my understanding is it is also right. 259 00:12:30,840 --> 00:12:34,080 Speaker 3: So your question to me is, Okay, it would appear, well, 260 00:12:34,200 --> 00:12:38,559 Speaker 3: this guy here seemed elusive in the problem. He didn't. Well, 261 00:12:39,040 --> 00:12:41,960 Speaker 3: if it's the design that I suspected, is where it 262 00:12:42,000 --> 00:12:46,520 Speaker 3: maintains pressure inside that tensioner. Ford may have more of 263 00:12:46,559 --> 00:12:48,320 Speaker 3: a problem that they want to let onto and they're 264 00:12:48,320 --> 00:12:50,559 Speaker 3: telling people something else. They had a problem with a 265 00:12:50,640 --> 00:12:53,760 Speaker 3: four point zero overhead cam engine. I don't know how 266 00:12:53,760 --> 00:12:55,719 Speaker 3: widespread that problem is. They still have it. 267 00:12:56,200 --> 00:12:58,680 Speaker 4: Well, the four to zero problem with the sock motor 268 00:12:58,679 --> 00:13:02,960 Speaker 4: in the Explore, that problem was addressed, And that problem 269 00:13:03,040 --> 00:13:06,559 Speaker 4: started out as the first issue that would cause engine 270 00:13:06,600 --> 00:13:08,240 Speaker 4: noise in a four to ozho sock. And I'm not 271 00:13:08,240 --> 00:13:10,199 Speaker 4: sure how we got to this, but a four to 272 00:13:10,240 --> 00:13:12,679 Speaker 4: oho sock motor had the problem because the tensioner in 273 00:13:12,760 --> 00:13:16,480 Speaker 4: the left front corner of the cylinder head right had 274 00:13:16,600 --> 00:13:19,839 Speaker 4: had had issues. And then the second step for noise 275 00:13:19,880 --> 00:13:23,520 Speaker 4: issues in the sock motor and the Explorers was the 276 00:13:23,679 --> 00:13:27,679 Speaker 4: chain and the tensioner assembly. And you know Ford came 277 00:13:27,720 --> 00:13:29,600 Speaker 4: out with a different design kit with a different set 278 00:13:29,640 --> 00:13:33,320 Speaker 4: of tensioners, and you know that resolved that problem. But 279 00:13:33,520 --> 00:13:36,640 Speaker 4: now going back to your Mercury to the grand Mark, 280 00:13:36,679 --> 00:13:38,120 Speaker 4: you have a five to four in that. 281 00:13:38,000 --> 00:13:40,959 Speaker 2: Correct four point you have a four to six. 282 00:13:41,679 --> 00:13:45,320 Speaker 4: Did that resolved to changing the tension resolve your problem? 283 00:13:45,360 --> 00:13:50,200 Speaker 3: Absolutely? The motor's quiet now. But if I had not 284 00:13:50,600 --> 00:13:53,000 Speaker 3: videotaped this and played it for them man, so you 285 00:13:53,000 --> 00:13:56,120 Speaker 3: could hear it in the audio with headphones, they never 286 00:13:56,160 --> 00:13:58,040 Speaker 3: would have found the problem. 287 00:13:57,840 --> 00:13:58,640 Speaker 5: To fix it. 288 00:13:58,760 --> 00:14:00,600 Speaker 4: Now, did they have the car and they were starting 289 00:14:00,640 --> 00:14:03,000 Speaker 4: it cold? Yeah, they did, and they just never heard 290 00:14:03,000 --> 00:14:03,560 Speaker 4: the problem. 291 00:14:04,000 --> 00:14:05,880 Speaker 3: They finally managed to reproduce the sound. 292 00:14:06,200 --> 00:14:06,560 Speaker 2: Okay. 293 00:14:07,000 --> 00:14:10,520 Speaker 3: Yeah, And like I said, Ford worked with me. They 294 00:14:10,600 --> 00:14:13,800 Speaker 3: replaced both tensioners, and I think it was around two 295 00:14:13,880 --> 00:14:15,720 Speaker 3: hundred and eighty five dollars He charged me for that, 296 00:14:16,240 --> 00:14:17,320 Speaker 3: a fraction of what it would have. 297 00:14:17,320 --> 00:14:18,880 Speaker 2: Caused, right cheap repair at that point. 298 00:14:19,000 --> 00:14:19,160 Speaker 5: Yeah. 299 00:14:19,200 --> 00:14:20,800 Speaker 2: Absolutely, this fellow here. 300 00:14:20,640 --> 00:14:22,520 Speaker 3: I think he said he's got twenty thousand miles on 301 00:14:22,560 --> 00:14:23,040 Speaker 3: his car. 302 00:14:23,240 --> 00:14:25,200 Speaker 2: Correct, But he also described it as a as a 303 00:14:25,240 --> 00:14:25,880 Speaker 2: lifter tap. 304 00:14:26,040 --> 00:14:29,480 Speaker 3: Well, it's not an easy noise, especially if you're not 305 00:14:29,520 --> 00:14:32,400 Speaker 3: a mechanic to determine what it is or what the sources. 306 00:14:32,800 --> 00:14:35,560 Speaker 4: But his problem, his noise was also he said he 307 00:14:35,640 --> 00:14:39,280 Speaker 4: described it as lifter tap and he also described it 308 00:14:39,320 --> 00:14:40,320 Speaker 4: that the dealer heard it. 309 00:14:40,360 --> 00:14:41,880 Speaker 2: Did he not record? 310 00:14:41,880 --> 00:14:43,280 Speaker 3: I didn't hear the whole thing, you do? 311 00:14:43,560 --> 00:14:45,320 Speaker 4: Yeah, I thought he said that the dealer heard it 312 00:14:45,360 --> 00:14:47,240 Speaker 4: and they told him that it was lift or rattle, 313 00:14:47,720 --> 00:14:50,440 Speaker 4: and you know that's again you know what noises are 314 00:14:50,440 --> 00:14:53,040 Speaker 4: hard on the radio. But bottom line, let him start 315 00:14:53,080 --> 00:14:54,960 Speaker 4: with oil pressure and if that doesn't take him in 316 00:14:54,960 --> 00:14:57,480 Speaker 4: that direction, I told him, call me back and by 317 00:14:57,520 --> 00:15:00,000 Speaker 4: all means, will convey the information about the timing belt 318 00:15:00,160 --> 00:15:02,440 Speaker 4: or the timing chain tension to them that you're talking about. 319 00:15:02,520 --> 00:15:04,880 Speaker 3: Yeah, well, oil pressure in mind was fine and it 320 00:15:04,920 --> 00:15:07,280 Speaker 3: probably would be fun. It hasn't easy enough to check, right. 321 00:15:07,480 --> 00:15:11,960 Speaker 3: I had the same problem, double overhead cam, a timing 322 00:15:12,040 --> 00:15:16,600 Speaker 3: chain tensional problem and a ninety five Nissan Maxima. And 323 00:15:16,720 --> 00:15:18,480 Speaker 3: I sell use cars and I see a lot of 324 00:15:18,600 --> 00:15:20,760 Speaker 3: used cars go through and it seems like Nissan scenes 325 00:15:20,800 --> 00:15:23,480 Speaker 3: have a problem even in the four cylinder with the 326 00:15:23,480 --> 00:15:27,400 Speaker 3: timing chain and the tensioner correct In the Maxima it 327 00:15:27,480 --> 00:15:30,080 Speaker 3: was a seventeen hour job to replace that. It just 328 00:15:30,080 --> 00:15:32,040 Speaker 3: didn't seem what was worth it to me to get involved. 329 00:15:32,200 --> 00:15:34,280 Speaker 2: No, And that's the problem with a lot of the 330 00:15:34,400 --> 00:15:35,080 Speaker 2: vehicles today. 331 00:15:35,120 --> 00:15:37,160 Speaker 4: You know the complexity of the engine and how it's 332 00:15:37,200 --> 00:15:40,120 Speaker 4: made you wonder if it's worthwhile to get involved. And 333 00:15:40,160 --> 00:15:41,920 Speaker 4: that's a whole nother story for a different show in 334 00:15:42,000 --> 00:15:46,200 Speaker 4: another time. But bottom line, I guess it still comes 335 00:15:46,240 --> 00:15:49,360 Speaker 4: back to something I always say with regard to you 336 00:15:49,360 --> 00:15:51,440 Speaker 4: want to change the oil every three months three thousand 337 00:15:51,480 --> 00:15:53,440 Speaker 4: miles because you don't want to get into having to 338 00:15:53,480 --> 00:15:56,800 Speaker 4: do engine repair because it's just too gush darn expensive 339 00:15:56,840 --> 00:16:00,600 Speaker 4: to do it. So if you can maintain the engine, 340 00:16:00,800 --> 00:16:02,960 Speaker 4: do your oil changes. And not that you didn't do 341 00:16:03,040 --> 00:16:05,680 Speaker 4: that with your Mercury, but to help avoid the problem, 342 00:16:05,960 --> 00:16:08,600 Speaker 4: change in the oil is still the best weapon against 343 00:16:08,840 --> 00:16:12,000 Speaker 4: having to take an engine apart unnecessarily as long as 344 00:16:12,040 --> 00:16:14,080 Speaker 4: it's a sound engine. You don't want to do engine 345 00:16:14,120 --> 00:16:16,920 Speaker 4: repair today, it's too costly. Hey, let's do a quick 346 00:16:16,920 --> 00:16:20,600 Speaker 4: piece of email. Hey, Ron Howdy from Dallas, Texas. No 347 00:16:20,720 --> 00:16:23,160 Speaker 4: love letters. I do have a couple of problems though. 348 00:16:23,320 --> 00:16:25,800 Speaker 4: I have a ninety four Geo Prism that has two issues. 349 00:16:25,880 --> 00:16:29,280 Speaker 4: Number One, sometimes a pop pop pop on acceleration while 350 00:16:29,320 --> 00:16:31,560 Speaker 4: turning to the right from a dead stop. The heart 351 00:16:31,560 --> 00:16:33,960 Speaker 4: of the acceleration, the more likely it will pop. I've 352 00:16:33,960 --> 00:16:37,640 Speaker 4: replaced both drive axles with rebuilts from AutoZone, and it 353 00:16:37,720 --> 00:16:40,280 Speaker 4: seemed like the pop developed a few thousand miles after 354 00:16:40,320 --> 00:16:43,240 Speaker 4: the replacement of the second drive axle. Not sure if 355 00:16:43,280 --> 00:16:46,360 Speaker 4: it's related, since my check of the axle seems to 356 00:16:46,400 --> 00:16:49,240 Speaker 4: be fine. From forty five to seventy the car develops 357 00:16:49,280 --> 00:16:53,360 Speaker 4: a shimmy only during acceleration, if coasting or breaking smooth 358 00:16:53,400 --> 00:16:55,400 Speaker 4: as glass. This is one car that has not had 359 00:16:55,400 --> 00:16:57,040 Speaker 4: one hundred and twenty hundred and forty dollars a month 360 00:16:57,080 --> 00:16:59,400 Speaker 4: spent on it for maintenance, and I feel very lucky 361 00:16:59,400 --> 00:17:01,680 Speaker 4: to have had to have this car. Not sure that 362 00:17:01,720 --> 00:17:02,880 Speaker 4: I'll be home, but if you like to call me, 363 00:17:02,920 --> 00:17:06,640 Speaker 4: here's my details. This comes to us from Mike down 364 00:17:06,680 --> 00:17:07,800 Speaker 4: in Dallas, Texas. 365 00:17:07,920 --> 00:17:08,840 Speaker 2: Well, I'll tell you what Mike. 366 00:17:09,840 --> 00:17:12,680 Speaker 4: The fact that it happened after the axles were replaced 367 00:17:12,680 --> 00:17:15,159 Speaker 4: you've got to eliminate the axles as a possible source. 368 00:17:15,760 --> 00:17:18,680 Speaker 4: Can you duplicate the problem up in the air, Can 369 00:17:18,720 --> 00:17:22,160 Speaker 4: it happen when the vehicle is driving only down the road, 370 00:17:22,200 --> 00:17:25,240 Speaker 4: or can you duplicate it on a lift? Try holding 371 00:17:25,280 --> 00:17:28,880 Speaker 4: one of the wheels, or do this all right? Determine 372 00:17:28,920 --> 00:17:31,919 Speaker 4: which is the drive wheel and it's probably the left. 373 00:17:32,200 --> 00:17:33,440 Speaker 2: Is the drive. 374 00:17:33,160 --> 00:17:37,160 Speaker 4: Wheel in that particular car that the right doesn't turn 375 00:17:37,160 --> 00:17:39,359 Speaker 4: when you're up in the air. If that's the case, 376 00:17:40,359 --> 00:17:43,960 Speaker 4: consider the fact that when you're under heart acceleration that 377 00:17:44,000 --> 00:17:46,880 Speaker 4: the steering wheel is doing that hula dance, that it's 378 00:17:46,920 --> 00:17:50,159 Speaker 4: a dead left inner plunge joint. You're gonna have to 379 00:17:50,200 --> 00:17:53,359 Speaker 4: take the axle back out, disassemble it, and look to 380 00:17:53,400 --> 00:17:55,240 Speaker 4: see is the tulip or. 381 00:17:55,160 --> 00:17:57,360 Speaker 2: The tripod of the plunge stuck in the. 382 00:17:57,359 --> 00:18:00,919 Speaker 4: Cup that it's got to burn it dragging the axle 383 00:18:00,960 --> 00:18:03,679 Speaker 4: and dragging the car in that direction under acceleration. 384 00:18:04,000 --> 00:18:05,240 Speaker 2: Pop pop pop pop pop. 385 00:18:05,600 --> 00:18:08,080 Speaker 4: Under load could also be the fact that it's stuck 386 00:18:08,119 --> 00:18:10,480 Speaker 4: on the burst. So look at that left drive axle 387 00:18:10,520 --> 00:18:11,080 Speaker 4: if that's the. 388 00:18:11,040 --> 00:18:12,960 Speaker 2: One, and let me know what the end result is. 389 00:18:13,000 --> 00:18:14,880 Speaker 2: I'm running ani in the car. Doctor em we're back.
