okay so i pulled my motor to replace all the gaskets and swap manual transmission on. car was original automatic. i replaced every gasket except the head gasket. didnt touch any internals and motor ran perfect before i pulled it. every thing is stock to pass CA smog. i ported and polished the intake manifold as well. finally got it all done and fired it up. ran perfect for the first minute and then just started dumping smoke. filled up my whole garage with smoke in a matter of seconds like i just did a burnout nomination. its definitly oil. theres so much getting in the cylinder that its literally dripping oil where the exhaust manifold bolts to the exhaust. checked the compression and its 190 psi all the way across. figured thats kinda high compression numbers probably because theres so much oil in the cylinder helping it seal off. but they are all perfectly consistent and high so the compression is fine so DO NOT tell me you think its rings. and valve stem seals wouldnt dump THAT MUCH oil into the cylinder, plus they were fine before i pulled the motor. and head gasket is completely wrong because that has nothing to do with oil and compression is good. i plugged off the PCV system to see if that would change anything and it didnt. im stumped here. the only thing i can think of is some how theres oil hooked up to vacuum and its getting in through the intake manifold. i cant find anything where there would be oil hooked up to vacuum. pulled my throttle body and i dont really see much oil in the manifold tho. I actually made a write up on here about the manifold assembly:

first off let me say great write up in that thread, you really took the time to get some great pictures. I find them very helpful as a novice KA mechanic myself.

Secondly, on to your problem, OIL is getting into your cylinders. First guess is already what you guessed:
"the only thing i can think of is some how theres oil hooked up to vacuum and its getting in through the intake manifold."

This is accurate guess work, as your other options are implausible, considering you have not touched the head (Right?) or head gasket. And all 4 rings would not go bad at once.

In your "cleaning up" and "re-routing" of vacuum lines you may have tapped the oil pressure sensor ? Or?
Or pcv somehow is no longer baffled well enough to control oil. Did you remove the valvecover? did you mess with anything inside it? Did you bake it (powder coat it?)

hey thanks man but i figured it out my exhaust was plugged. left it outside and it was filled with water and rust. hella back pressure made hella blow by in the cylinders. its all good now
