So I have noticed that I am burning oil but it only seems to happen at idle. It's intermittent and I never notice smoke after I accelerate from a stop or while cruising. Any thoughts to what it could be. I thought it was only when the engine was cold but it does it both hot and cold. I'm hardly the mechanic so i haven't done much in the way of diagnosing. I do know that cylinder 4 was about 20 psi lower than the other 5 during the leak down test (140# vs 160#). Could that be the issue? If it was a ring why would it not smoke all the time?
Thanks
