Hey Manolito, thanks for the reply, i suspect you are right, the car has alot of km's on the clock, surely if i have blowpast the rings it would smoke all the time, cause as soon as i've cleaned everything it on the intake side, it doesnt smoke, even if i rev it up, i'm next to certain now it must be that pvc device that isnt funtioning properly, i also tried to open it but stopped when i saw it was going to break if i forced it, seems like bmw manufactures them that way, once its clicked together it wont come apart. any idea whats inside the pcv that makes it work? someone told me that i should just blank it off, not sure what he means though, i dont feel thats wise any suggestions?
thanks chris
