Head gasket or EGR cooler?

    Here's the deal. I have oil and coolant on the rear of my right (passenger) head. I believe the oil is coming from the PCV, blowing out of the rear of the EGR cooler. I have it blocked, obviously a bad gasket seal...

    I am entertaining the thought that it could be coolant coming out, too. I've added about 2 pints of coolant over the past 30k miles.

    I was curious if anyone else has had similar issues. If it's getting head gaskets, it's getting studs. Just don't want to go that deep if it's the EGR cooler...

    Might be time to bypass the coolant lines to the EGR cooler and see if the ooze comes back...

    Or go with a coolant dye. They work wonders at finding small leaks

    Probably not head gaskets because they tend to blow all the coolant out of the surge tank and leave a black residue (soot) in the tank.

    Are you still under warranty?

    Yeah, still under warranty, but I'm not going to send it in for one. I'll probably wait and pull it to do head studs and new gaskets, both sides. I'll see if it gets worse. Hell, I could split a piston pulling and be yanking the thing out anyway...

    I was curious if anyone else had noticed anything similar. My buddy's '01 was weeping in the same spot as mine, and never got worse. didn't get better, either...
