I read something about the skirts in the GM engines being too short, resulting in piston slap and knocking.

In my opinion with a Chevy, the only engine worth dealing with is the 4.3 v6. It's been around for 20 some odd years, and has done fairly well.

There is a lawsuit over the GM engine issues as well.

Apparently, Ford is doing better with customer relations according to www.pistonslap.com. Go to the link "what others did" and look around, as well as read the description of the problems they've had. Much larger than the 6.0L. Also, there is photographic proof of the issue, just look under the photo section, a 8.1 with only 17,000 miles, all scarred up on the cylinder walls, and scored and scratched pistons.

 

HeyMW95250 Its quite a serious issue with there gas motors and Im afraid the new ones arnt any better. People still having problems. I am advising everybody I know to stay away from GM trucks until they get this issue resolved. People must be listening GMs truck sales last month were horrible even with better discounts than ford. I think it will take a total engine redesighn to remedy the problem.

 

LOL

really?
how much experience do you have with it????


it most certainly can, and WILL score the cyl walls, and piston skirts...and it does not take long.

 

Going to put in my two cents:

I'm a mechanic at Woodhouse Ford in Blair, yes the worlds largest F-series dealer, and within a few years, probably THE biggest dealer. I'm not a diehard ford guy, I drive chevys to work!

6.0 Problems: Someone turned the cranks wrong, engines needed to be replaced, not one made it out to the public; injectors dying early, if not caught, will burn up pistons, the new injectors have had no problems; had 2 come through that had been propane injected and chipped, the injectors couldn't keep up and the engine burned (one even had on the customer complain section that it "wouldn't do over 100 anymore", nevermind he was pulling 12,000lbs behind him too)

Duramax problems:Warped heads blocks, injectors, cracked pistons, bad rings, and they can't hold up to more than a 120hp boost chip... Because of the heads...

And don't think we don't see duramax engines, the chevy dealership is right across the road, and we trade help a lot... We actually do more chevys than they do...

EDIT:::

I mean who puts aluminum heads on a work diesel! Mercedes (the worlds oldest diesel manufactuer) doesn't even do it on their work diesels, there are only a few car diesels that ever had aluminum heads.

 

Well this thread sure is quiet now. Nothing like a mechanic to fill us in on problems with these diesels.

 

Yup, Nothing like a FORD mechanic telling us all about GM diesels

Hey, got a Bridge I wanna Sell, Interested?

 

arthurbrownlee,
can back up your post with facts about the Duramax? If not don't, bring a proven motor and tranny combo down to the 6.0 level just because your a Ford supporter.

just my $.02

 

Hey where were you guys before. Takes a guy like me to stir things up and get this thread going again. Trouble is GM mechanics say the same thing.

 

Can you prove that I am wrong? What would you like me to do, copy the work orders for them? All I know is that I am a car/truck guy. There are things wrong with each brand, and products I wouldn't buy from each brand because I have seen the common problems with them. (5.4 ford guys, you know about the headgaskets *not the 04 5.4 though) I am not saying for everyone to believe me. I don't expect them too. But do look at some of problems with the duramax, most of them happend just because Chevy doesn't have that much experiance with a GOOD diesel. It is not an Izuzu engine, it is a partnership deal with GM. This is a GM diesel with some Izuzu designs.

I personally am still happy with the old Ford 6.9s with aftermarket fuel and turbo systems.

 

Hey arthurbrownlee these guys think the duramax is foolproof compared to the 6.0. Hey I believe you. You have mechanical experience with both.

 

My bosses 2500 HD's Duramax was R2 at the dealer after 80,000 miles. Since then no more Duramax equipped trucks have been bought but the order list for super duties sure has grown both with the 5.4 and the 6.0.

 

Could someone translate, please? R2? Order lists?

 

Hey ALB. I believe you. This is exactly the kind of problems my friend informed of. The nay sayers woudn't believe me either, but I wasn't making anything up, and I'm sure, that you are also just honestly reporting what you know.

 

I'll agree that Chevy hasn't had a real good TD until the Dmax but I hate to break it to you the Duramax is made by Isuzu. If you'd like some more info I can provide it for you.

As far as proof I guess I'd like to see some. If you don't know who the motor is really made by I really have to question your other claims. I'm not saying that the Duramx is 100% bullet proof but compared to the 6.0 it's pretty dare close(Please refer to my other post - Cummins can't be all bad with JD powers numbers).

 

Hey, don't forget the wonderful early (pre-PI-head) 4.6L intake manifold design... there's at least one class action lawsuit going over *that* fiasco. "Sorry your intake manifold cracked and is spewing coolant all over your engine bay, but if you're not a Crown Vic (I.E., cop car) we're not going to replace it and we'll claim it was abused if you ask why. Oh, and the recommended replacement part will do the same thing." Leaving all the trucks and Mustangs out in the cold - and most of them *will* have this problem, if they don't already. Thanks a lot, Ford!
