Define alot. What exactly did you see?

It doesn't take 2 days to seep through. In a good engine, oil covers the valve stem. The seal keeps it out of the guide. With old seals, there is no seeping, but oil runs down the valve through tiny gaps in the seal. Within a few minutes of shutting the engine off, the oil runs down.

My thoughts are:
* you can change the seals and *hope* that makes a difference
* you can do a 15 minute compresion test and know if the rings are bad and if so, changing seals won't fix it


Quote:Mainly -- change the oil before starting the engine. 8-year old oil won't seal or lubricate properly.
