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?

 

More pictures.:





Stems were put on correctly and correctly seated.

PCV fail??

 

An update:

Took everything back out. Checked every valve stem seal, they were all correctly on. Gave them an extra tap to be 100% sure. Still smoking like you wouldnt believe. White smoke, barely any at idle a shit ton when you rev. Oil still coming out of exhaust.

Tomorrow I plan on doing a leak down test.

 

Not sure what a leak down test will do for you...you stated you had good compression. This has to have something to do with the install of the timing chain tesioner or the PCV valve. When replacing a timing chain did you replace the chain tensioner too? The PCV valve is cheap and never hurts to replace one.

 

In my case I wanted to see how much air was getting past the rings. Leak down test came back good. Injectors are spraying fine. Disconnected PCV smokes less on idle still smoking a shit ton on rev up. No blow by out the oil filler cap.

This is not my first rodeo. Timing chain is OEM and was put on to spec per FSM.
