Just following this discussion and have a question. My '85 300CD with 138k miles has a bit of oil in the air cleaner housing. Nothing on the element itself but a little bit around bottom where it sits and on the internal metal parts of the air cleaner housing.

My car starts great down to 17 degrees F (as cold as it got here this winter) and uses about one half quart per oil change. I use synthetic oil.

There is a bit of leakage at top of engine where rubber hose connects valve cover to air cleaner.

Anyone know what might cause this? I understand "blowby" is caused by worn rings but my compression seens good.
