- 1989 DARK BLU METALIC SIX SPEED CONV
I have a 1989 Corvette Conv and I recently repalced the valve cover grommets on both sides but on the dirver side cover ther still appears to be a small leak from the PVC vavle grommet. Could this be a blowby situation or could exhaust back pressure cause this? When I purchase corvettes, I usually have the exhaust checked for back pressure, but have not got around to it. The motor just turned over 90K and I think its to soon for a blow by (worn rings) Interested in hearing advice on how to seal the grommets.
