So my valve cover gasket (OEM) with less than 4K miles on it is spewing oil from the rear passenger side. I can’t tell if that’s the only place as well. Car is a 93 240 wagon with 204k miles. Just recently I noticed palm size oil spots after parking overnight. At first I thought it was a bad pan gasket but it appears to be leaking down the head by cylinder 4. I think I have excessive crankcase pressure to blow a gasket that quickly. I never replaced or cleaned the flame trap either. I have the parts, but it looks like a huge PITA and I’ll likely pull the intake manifold to make it easier. Thing is I live in Massachusetts and it’s winter without a garage. I don’t want to spend a small fortune having a shop do something I can do also. So my question is this:
Would pulling the valve cover and drilling 1 or 2 ports for a crankcase breather line into a catch can or just put a small filter that vents to the atmosphere get me through until spring when I can replace the entire PVC system the correct way? Parts yards have lots of 240s here and I can grab a valve cover from there to put it back to stock. I don’t have emissions or anything here. Would putting 2 breather ports into the valve cover lower crankcase pressure enough to prevent future seal and gaskets from getting blown out? I’ve had cars in the past with this setup and it worked on them.
