E46 318 n42 2001 sedan

so now my problem is that it smokes at takeoff after idle or stood idling at a trafic light
so i disconected the vacuum line from the CCV on top of the intake manifold and plugged the intake manifold
i saw some oil in the hose,so F-up CCV valve

i started the car and out of the vacuum hose still conected to the CCV came some smoke and blowing air
since i've don that it is eating oil and when it starts to smoke it smokes more
most of the time it doesn't smoke but when i cut off the engine and let it sit for a while and start it up and drive off it does not smoke

is there a second vacuum line on this CCV hoses setup to the manifold ?
i haven't pulled the intake off jet
so i have no clue on how the state of the hoses are of the CCV

i have ordered a new CCV kit with hoses

i will do a compresion test on all of the cylinders
does anyone know the pressure that i need to get out off the cylinders cold or warm engine

I have a 97 540i that did the same thing. It was the pcv vent valve on the back of the intake. Replaced it and was good to go no more smoke
