Corvette 8-cyl

  • 69,000 miles


The cylinder heads at 69K miles were checked due to excessive valve train noise and the valve guides and one intake valve were found to have clearance more than double the service tolerance.

The harmonic damper on 2006 Corvette with LS2 engine failed resulting in power steering drive belt coming off pulley causing loss of power steering. The high effort required to steer vehicle almost resulted in crash. This harmonic damper issue is documented in numerous internet forums and is believed to be a widespread issue that should be recalled and corrected by the manufacturer.

According to Corvette forum, this is another widespread problem- the harmonic-balancer becomes warped and requires replacement... if not done timely, other "parts" could be negatively impacted as well...

Noticed a loud ticking from valve train. Had heads removed and found exhaust valve guides were out of specification after 11,000 miles by 50%. had to do valve job on heads because Chevy denied claim. Now a recall out for 08 and newer but no coverage for 2006 and 2007!

I was driving back home from lunch with a friend I haven't seen for a while, car ran flawlessly up to the loss, dropped him back off at his car and we parted ways. Then on my way home, making a left hand turn, going about 40mph, 3rd gear cruising along all of a sudden the car sounded like the exhaust came loose, followed by a lot of engine noise, followed by a large white puff of smoke from behind. I had a extended warranty that was by Mercury and they denied the warranty due to abuse. Went to a race event 3 months prior and did 3 races on a straight away from 50-130, found footage of my car on youtube and they claimed that was the reason why I blew my motor. They said I either had to deny that and risk getting charged with fraud or admit that was me in the video. This will definitely be the last GM I ever buy. Now left with a useless car and having to pay out of pocket for a new motor.

Massive engine failure due to a failed exhaust valve after inspection, car lost all power and was immobile after rolling to a stop. The 7 and 8 cylinder on the block were completely ventilated. This is a very common problem with 2006-2011 corvettes and many others have had the same issue.what happens is the head of the exhaust valve falls off and then it makes contact with the piston and takes out the block and piston and rods. Please investigate this as there is several hundred or more Z06 equipped with the LS7 motor that has had the same issue. It is a safety concern and imho there should be some kind of recall on these motors.

Started hearing squealing sounds a few weeks ago. Noticed the crankshaft pulley had a noticeable wobble. Did a google search & found multiple reports on forums, youtube and such of of others with the same problem. Also my friend with the same car but a newer year just had it replaced under warranty. My car is off warranty but a harmonic balancer should not wear out in six years with just 7,500 miles (yes, seven thousand five hundred). My 2000 Ford Expedition has 151K. Chevrolet wants about $1,000 to replace it.
