Default Has anyone figured out why the 2.8 will leak oil from the Oil Filler Cap? Annoying issue.
I've been living with this oil leak from my filler cap for....I don't know how long. To do a search only produces all the stuff I've already done: replace the breather hose, the suction pump (valve), and check for vac leaks but leak still there.

Any one ever figure this one out? I've got a valve cover/cam tensioner seal leak on the passenger side and before I get that fixed I would at least like to have a new theory on why the oil pressure keeps getting so high that it leaks through the cap.

Do you have the rubber gasket that goes between the cap and the valve cover?
