Description of the problem | 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, i took my car with 27000 miles on it to a corvette specialty shop to have my valve guide clearance tested. I had (2) intake valve guides outside of service specifications, (4) exhaust valve guides outside of service specifications, and a combination of (10) other intake and exhaust 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. 88% of the corvette forum members who have had their cylinder heads tested for excessive valve guide wear, were out of service specifications.

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. |
