CJ Carbon build-up on S/S valves
How much is to much? New S/S values with 5000 miles showing a significant amout of carbon build-up on the intake valves. Is this normal or should they be as clean as the exhaust. What causes this build-up and is it causing me a loss of performance? Thanks for your support Fran
P.S. I discovered this while changing the intake gasket.
