C6 Z06 Defective Engine Lawsuit

GM Hit with Class Action Lawsuit for Defective C6 Corvette LS7 Engines - Corvette: Sales, News & Lifestyle

I'm a diehard Vette and LS motor guy and this really upsets me to hear about this. Didn't realize this problem was that bad.

I believe it. Hopefully GM loses. Fuckers.

 

[Spivitz]

Yup, bad news. A guy I know put 526 miles on his ZO6, no mods, never raced and the motor blew.
GM took care of him though, got him a new car.

 

[Turbocharged400sbc]

it's not just the ls7 a lot of other GM engines are having massive valve guide wear issues...

 

[blakbearddelite]

Almost as bad as the massive 5.0 recall.....oh wait.

 

[SleeperLS]

Wife's cousins z06 blew up and all he did was drive it. I think it had like 50k ish miles on it. Stock except cat back. But, it is out of warranty. So, he is out a lot of money.

 

[Ti28]

I hope everyone wins, and Im a huge GM and LS fan. But it's bullshit.

 

[P40E]

Aluminator xs 5.0 swap .

 

[zenriddles]

This smacks of the Camshaft issue on the V8 SHO's of the late 1990's.

Dear car owner - yer fucked. Fix it yourself pre-emptively or drive a time bomb.

Ls3's like to develope lifter issues.

 

[Rent Free]

C7Z has had a lot of issues from not meeting the claimed specs to engine failures. GM said meh just change the oil. I hope GM gets these issues worked out ASAP since GM shares engine in a lot of cars. I'd expect the ZL1 Camaro to get the LT4 just like the CTS-V and C7Z.

Ls2 have rod knock issue due to poor oiling and oil starvation. Awd tbss are the worst... with a retarded oil pan design.

 

[SHARKBITEATTACK]

i wonder if they fixed this problem on the later engines. I think that 60th annivery convertible vette uses a LS7 as does the Z28.

ALL LS7 engines have this problem. ALL. If you own an LS7, get the guides done.

BTW, I am one of the original 19 plaintiffs that is bringing this to GM.

It's not rod knock, it's piston slap, alot of cars have it until they are warmed up.

But yes, the TBSS pan design is fucking retarded.

 

[Chester Copperpot]

Government Motors say valve guide wear is feature, not issue, komrades. It allow piston top oiling for more efficiency and horsepower.

It's not rod knock, it's piston slap, alot of cars have it until the are warmed up.

But yes, the TBSS pan design is fucking retarded.

Dem short skirts doe.

 

[Ti28]

Dem short skirts doe.

POOOOOOWWWWWWWAAAAAA

 

[Chester Copperpot]

I wonder if this will cause others to bring up more suits because GM is fucking garbage.

The piston slap issue as noted above of all LS engines, the myriad of issues with the garbage suspension on the GTOs, etc.

THat too... sounds like a old clunker for the first 5-10 minutes.

But they have rod knock issues as well. There is a long list of people with blown motors (spun bearings) at 60k to 100K miles.
The trick is too run extra oil to help reduce the oil starvation. But it doesn't work 100%, especially on the TBSS AWD oil pan.
A higher flow oil pump helps to. The circulation of oil inside the motor is not adequate.

IT's not just the AWD, it's both. They both have the same pan. Yes, extra oil was a patch job. But now PCM4less has new pickup tube.

Ls2's do not have a priority oiling system. And it's normally the #6 rod that gets the beating from oil starvation.

but who cares about the piston slap... i'd still rather have that issue in a 2000-2007 gm pickup than the shit gas fords or dodges from that era had...

 

[Yaj Yak]

don't the escalades/denali's drop valves too?

 

[twinv6gtp]

Yes I made a custom pickup and baffles in my awd pan to reduce the chance of it happening again.

 

[Stink Star]

GM DOD v8 engines eat lifters and cams like it's going out of style, but it pays the bills so I'm ok with it

 

[SleeperLS]

My cousin in law is cheering you on. Good luck with the case!
