Rear main seal leaking after changing PCV?
I've always had a slight drip from my rear main seal, but yesterday after finally putting in a new PCV valve it is leaking really bad.
I was about a little over half a quart low on oil from the leak. After topping off the oil and putting in the new valve it is leaking worse now than it ever has.
I know it's possible that the new PCV valve is bad, but I can hear the ball rattle around inside it and seems to be fine.
Do you guys think that it's just coincidence that my rear main has finally gone completely or am I overlooking something here? Should I just remove the PCV valve from the valve cover and see if it goes away? I know that if the engine is building internal pressure and it can't go anywhere that major leaks can occur.
I really don't want to pull the transmission and transfer case, but that's my only choice at this point.
I shop in the salvage yard.
