if i remember correctly when you got the car it was not running .. you do not know what the previous engine ran like .. i suggested several threads back that perhaps you are just now burning old oil residue from the exhaust of a poorly running previous engine .. put a few more miles on it .. if you think the PVC system is the cause you can look in the hose itself for evidence of fresh oil .. i dont remember if you have a stick or an automatic .. if an automatic check the modulator valve on the trans .. have you actually smelled of the smoke ? .. oil smoke will of course smell like oil .. coolant smoke will smell a bit sweet .. i haven`t snorted trans smoke in so long i dont remember ..
