Hello, After getting my car back together and doing some spirited driving again an Evo 10 today, I started to get a horrible blue smoke of of the valve cover nipples and slight smoke from the exhaust. Currently have a catch can installed as well as NGM valve good for 40psi in place of the stock PCV valve. Car is currently running and idling properly, just loads of smoke out of the catch can with actual oil buildup. I have not done a compression test, but I have checked the oil and coolant for signs of head gasket failure, but there has been no mixing from either. I’m going to lean towards either bad piston rings or valve seals. The smoke has been pouring out of the exhaust nipple on the valve cover. I have some pictures, and will post them later. The car currently has the stock camshafts and intake manifold currently, just with low compression pistons. Thanks for the help. ---

Cracked ringlands? Blue smoke is most definitey oil burning off. If it’s coming out of the valve cover, burning oil is getting into the head itself somehow. Smoke out the exhaust is almost always indicative of oil getting past the rings as well. ---

Did a compression test today. I’ll post the pictures and since they do most of the explaining.

Cylinder two and three did not. Going to be dropping the pan and pulling the crank down to see the chaos this week. I’m happy it held up that much. 🙂 ---

That sucks Sean. Well, you either fuxxored the rings…or blew the gasket in such a way that it is not (yet) burning coolant. ---

Very close to the 4G63’s. The head has the most difference. Just ordered a motor from All Foreign and picked up a timing belt to throw on. Hopefully I’ll have the shitbucket back up this weekend. ---
