KA24DE Head filling with oil - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Long story short. Compression is fine across every cylinder. Tops of pistons are clean (can even see .50 or whatever it says), spark plugs look fine. Car runs as if brand new.

Replaced valve stem seals while I was doing timing chain. Now car is smoking like crazy, gets worse when it reaches operating temperature. Small drops of oil coming out of exhaust.

I noticed the head keeps filling with oil, reference puddles next to shims in the pockets of the head, fills up on top of shims. Assuming oil is leaking down causing it to smoke.

No idea why it is doing this. Any ideas?
