with 230,000 miles, anything is possible, and certainly rings fit the symptom. (although the oil control ring would seem to be the least likely of the rings to be the culprit here, imo) i just wonder if doing a ring job solely is the correct way to go on this engine, i.e. you are probably looking at doing a whole lot more once that baby is opened up.

HOWEVER, i'm talking generalities, and hopefully a more specific diagnoser with this engine will chime in....

what have your 'guys' done, diagnosis wise ? compression test? wet compression test? leak down test? these are some of the tests that can help isolate your problem.

and, btw, change that pcv valve, just in case <img src="/forums/images/graemlins/wink.gif" alt="" />
