Re: Jeep I-6 engines have a blow-by problem!
This is common with the inline 6, there are two lines coming off the Valve cover, the one in the front allows air to flow into the valve cover and is about a 1/2 in hose the second is a small vacume line on top towards the back of the valve cover and is a vacume line, if it is clogged or the little baffle built into the valve cover below is clogged then you will eventully will notice oil on you air filter. Check the small one first.
