Default Re: '49 8BA Valve stem seals

There is a distinct difference between valve guide seals and valve stem seals. You won't have valve stem seals.You will have guide seals and very little gets past the guide fit to the block after a few years of running.The worn stems and guide are usually the culprit along with a worn set of rings,there is no magic fix for this scenario.Worn guides respond well to good vacuum.Trouble shoot it with a serviceable vacuum gauge.
