[Z06] NHTSA: File a Complaint - Valve Guide Issue
#242
It depends on the age and mileage of your car. GMPP extended warranties can go for up to and over $3K if you have over 24K miles. I think this was for 3 years. I don't remember the mileage, though. For me, it wasn't worth while as I still have the PT factory warranty. They'd have to run parallel and makes no sense for me to get it.
I've also hear cases on some extended warranties where if the repairs are very expensive, they return all your payments and then tell you to pound sand.

New here today hope im on the right spot. My story is much the same. Back in '13 was my problem. I won't rehash. I have a Gm replacement motor cost just north of 17.5k the damage was quite extensive. In the parking lot of local target at idle. 27k for miles. Thankfully not on the road with my daughter or wife. I was 30 plus days out of warranty. An 08 Z06 it falls into the gap. I won't go into dealer issues. or my treatment. Its pointless. I tell my story to those who ask where is my car or about my experience owning a Z06. My stories bring no comfort to fellow owners or those wondering where to put cash. I can say it was a great experience owning a car with out issues. I have put on less than 500 miles since the new motor. I'm close to my last payment and will cash out. I was told by a employee at the dealer ship I was like a kid who had his lunchbox taken on the bus. Any recall that happens will not be related to the issue at hand. When correct its an amazing machine and the majority will never reach it's potential. Cool forum guys I have been reluctant to join yet another forum but wanted to add my name to the greater issue at hand. A rather large scam by GM. The lengths I have been mis directed is unreal. I'll look around now thanks Van

Mine's going into the shop next week...
WoW.......I was shocked, I started with the #1 cylinder and as I was putting on the spring compressor I just pushed on the intake valve
(spring on) and it felt good, so I PUSHED ON THE EXHUST.....I could wiggle it,,,, (spring on) back and forth a lot. I knew I had dogged a bullet doing this....The car has 33,000 2007, just a every day driver, never on a track, was running great, on oil use, no noise...nothing.
I removed the springs, put a dial indicator on and intake, it was 0.05 to 0.07, moved to the exhaust and got 0.35...wow, you could make the needle go almost 180 degrease on the dial....There is no need to proceed.............heads are coming off................Compliant filed.........I have built engines all my life, unlimited and limited hydro's, drag boats, aircraft......I have only seen guides like this at 250,000 hard miles........................

I'll see if I can't get measurements when they tear her down, and post them as well as file a complaint. It's a 36,000 mile machine, 2007 Z06.
Thanks, folks. You may have saved my bacon with this information.

Agree with that! Wish I had done that, but I skated really close to the jagged edge of the thin ice. Found a nasty clatter; Big Red's going into the shop next week for surgery. After I get the information, you can bet your sweet buns I'll be filing a complaint.
Oh, and my ace mechanic says we are going to bronze rocker bushings, too; needle bearings headed to the trash bin.
Thanks for this thread!

Aye, Matey, and twist the knife as ye shove it in...

Each dealer likely handles this differently; This is how my purchased new January 4, 2008. 10,000 mile, extremely well cared for; Summer only driven, oil changed at 250mi then 500mi during break in. Now once a year minimum, or 3k miles.
I arrived at the dealership as scheduled last spring complaining about what I thought to be excessive valve noise.
The Corvette tech listened and proclaimed, "That's the injectors."
The head of service stated. We will wiggle test, if the valves are within specifications you will be responsible for the bill; With labor approximately $200.00.
If valves are found to be out of factory specifications, we will repair the valves and guides that are out of specifications, on extended warranty.
I said, you would dissemble an engine and not do a complete rebuild on "BOTH" heads?
No, a regional Representative will come and inspect the parts and make a final decision. They may cover the cost for replacement heads/rebuild; However we cannot guarantee, that will be the outcome. You will be responsible for anything not authorized.
I drove my purchased NEW, $80k, Paid in full, 10,000 mile Z06 home and have spent this winter first with a WCCH top of the line rebuild. (a tad over 4k) I also canceled my one of two, the dealership was allotted, 2015 Z06 Corvettes, placed a year ago.
I also filed a complaint, and am part of the pending suit against GM; Angry would not explain how betrayed I feel.
When needing to replace my daily driver, I headed to the Lexus Dealer. There is a special ordered new RFX 350 parked in the shop with my Corvette and Dodge Diesel PU.
Well the Lexus is no longer new, just went past 13k the other day. Valves are working well, as is all the mechanical parts and pieces of that vehicle...
Until the valve issue that dealership had done an excellent job, replacing/repairing various issues. I have since 07 brought gifts to the service writers and the Corvette Tech who performed the work.
This last Christmas, I did the same; Only this time I had something extra. Both valves and corresponding guides for their inspection.
Graven were the looks of both departments as they were handed the parts for inspection. One doesn't need instruments to determine the wear, as one can move the valves side to side with enough clearance there is a "tink" as the valve contacts the side of the guides...

Mine just dropped a valve yesterday. Its a 2007. I talked to the local service manager and trying to talk to the regional. I will file a complaint when I know who I am going to have repair it. most likely if I cant get Chevy to pay something, I will be yanking the engine myself and finding a machine shop to re work it.

I just filed my complaint. I did it over the phone and spent 20 minutes going into fine detail of what happened. I also stressed the fact that an engine failure like this could easily result in locking of the rear tires under certain conditions and is a huge safety issue.
Good thing Vette drivers are usually better than average drivers.

I was going to do it online, but it would not accept my VIN through the web site.

I have also filed a complaint here http://www.carconsumers.org/
I would recommend anybody with the same issue do the same. maybe if we can get some media pressure on GM they will do right by us.

Raw wiggle test done by AHP.
2007 Z06 23884 miles
I got it at 22890. Previous owner did not track the car.

#8 int .007"

Max GM spec is .0037" which would roughly be .0075" on the wiggle test. So basiclly if the wiggle test is over .0075" the guides are out of spec.

Car is currently at AHP for some work, and had the wiggle test done (~15,000 miles).
Wiggle test results are as follows:
#1 int: .012"
#1 exh: .0125"
#2 int: .007"
#2 exh: .007"
#3 int: .013"
#3 exh: .010"
#4 int: .011"
#4 exh: .010"
#5 int: .011"
#5 exh: .012"
#6 int: .013"
#6 exh: .012"
#7 int: .011"
#7 exh: .010"
#8 int: .009"
#8 exh: .010"
If I'm reading these values correctly, my #2 cylinder is borderline and the rest are bad.
I'll be filing my complaint...
