Re: Valve Stem Seals

I don't doubt there are some applications that the seals do fail, but on the gen I chevy small blocks this never seems to work. We replaced the o-ring types and added umbrellas to try to stop the notorious blue cloud on start up, and it never did the trick like resizing the guides did. Don't let anyone talk you into knurling the guides either, this is also just a band-aid.
