I'm somehow leaking exhaust into the head cover. I have already replaced the head gasket and the valve seals trying to troubleshoot myself. I have very low compression in cykinders 1 and 2. Why? And how do I cure the exhaust buildup in the head cover?

Hi there,

I feel that the problem is faulty piston rings, the back pressure is not exhaust but engine compression bypassing the rings and over pressurizing the sump and top end. You can do a wet comp test to prove this theory, add a small amount of engine oil to the cylinders and do a comp test, the oil will make a temp seal around the rings and if the comps rise the problem is in the rings. Start here.
