Wear issue is with the valve guides in the cylinder heads. If the issue was not addressed, the hollow, sodium filled exhaust valve could break and destroy the engine. The repairs were made before the car had an engine failure while driving. Mileage on the car was around 32,000.

While driving on highway in 5th gear #5 exhaust valve dropped into the cylinder going through the piston and causing connecting rod to go through side of the block. Engine seized and caused the car to go into a 65 MPH spin. Luckily this occurred late at night on a open 4 lane highway with little traffic. I nearly clipped an oncoming pickup truck but squeaked by him. The car had 32,000 miles on it but out of warranty because of the years. Total cost for this ls7 replacement cost me 18,000 out of pocket. I hardly even drive the car because I'm afraid of it happening again. I'm reluctant to sell it because of the valve issue happening to potential buyer and them coming after me for the failure. Gm needs to correct this problem before someone gets killed like I could have been that night.

Engine knock on 6.2 liter engine. When the vehicle sits a knocking occurs in the engine upon startup. It is not a lifter knock, but a knock deeper in the engine gm has noted the problem and made multiple repairs (6+) cam shaft changed but no lifters. Thought this was odd as the wearing surfaces are now dissimilar .gm said this is all they authorized. Knock still present gm then removed upper end of engine. Noted extreme carbon build up on multiple pistons. One piston had so much building apparently close to valves hitting. Gm tech advised engine replacement, gm authorized cleaning of pistons: guess what, knock still present the knocking is a piston or lower end knock. Similar to wrist pins or rod bearing caps or bearings. When knocking occurs engine is rough and pulsates. Time ranges from 30 seconds to couple of minutes after multiple gm repairs knock is still present, noticed engine performance is not the same and with lack of stability fuel economy has dropped

I was concerned about excessive valve train noise and after reading several corvette forum threads about improperly machined heads by gm's supplier linamar, and that numerous vehicles have had valves drop and ruin the engines, loosing a valve while driving will result in loss of power assist for steering and breaking while on the road . I took my car with 13500 miles on it to a corvette specialty shop to have my valve guide clearance tested. I had (8) exhaust valve guide and (3) intake valve guides outside of service specifications, and a combination of (5) other intake valve guides at or near the maximum outside of service specifications. The car is being repaired with proper re-machining of the heads to make the valve guides concentric, new intake and exhaust valve guides installed, as well as new seals, valves, springs, etc. I can provide data on the failed guides for documentation 88% of the corvette forum members who have had their cylinder heads tested for excessive valve guide wear, were out of service specifications. Source: http://www.corvetteforum.com/forums/...-registry.html gm needs to issue a recall on this issue, there have been numerous engine failures as a result of a dropped valve into a cylinder which can cause accidents and fires. Gm is very aware of this issue, but refuses to do anything about this huge safety risk to drivers, passengers, and nearby vehicles if the engine fails going down the road.

Engine started making noise, feeling there could be a failure I drove to my servicing chevrolet dealer. They listened to the engine and said, that's normal. Not trusting that judgment, I had an independent shop inspect the engine, and had the valve issue resolved at my expense. I was still under extended warranty, which made me angry. But if the dealer says there is noting wrong, what am I supposed to do? After the repair was performed at my expense, I took the failing parts back to the dealer for them to inspect. They admitted they were wrong, but what good did that do me? Keep in mind my vehicle had less than 10k miles on it. This is where I feel safety comes into play; had my engine failed and locked up on todays crowed interstates, I could have caused a major accident. The failures I have read about, gave no warning, when the engine let-go.
