This sounds like valve seals or valve guides! The oil in the head slowly seeps past the valve seals, or guide, and gravity pulls it into the cylinder over the course of the night. The oil builds up enough to see a noticeable cloud in the morning and then the oil is gone. There is a difference in characteristics between valve seals and valve guides.. I forget which does which.. But I know that one will do this only on a "1st start in the morning" and the other will happen during high RPM acceleration.. Similiar result as bad rings or scored bores. I wanna say the valve seals are the culprit when it's only in the morning. I don't think piston rings would be the cause in the morning start oil burn issue. But I'm not sure. Good luck! <img src="/forums/images/graemlins/smile.gif" alt="" />
