1989 SBC Valve Stem Seals
I've got a 1989 SBC with a one cylinder fouling the plug and using oil but does not smoke. The engine has been rebuilt and runs great, don't know how many miles are on it. It takes 800-1000 miles for the plug to foul and it uses at least a quart every 2000-3000 miles.
Is there a chance it's the valve stem seal(s)?
The parts stores list both the o-ring type and umbrella style. If it is the umbrella type should it have failed so soon? I know the old style o-ring seals are crap but the umbrella type work great.
