Hey i just put a new 1.5 in my car, and its smoking horribly bad. I did a compression test, its ok. i changed cylinder heads to one with brand new valve seals and its still smoking really bad. The smoke is a white-blue smoke, im guessing burning oil. but i dont know where its coming from. I noticed a horrible build up of carbon on the pistons before i put the head on but i dont think it would cause this bad of smoke. Oh and it smokes on acceleration and just cruising also. All help appreciated. -Ben

 

try doing a leakdown test on it. itf all that checks out okay id say it may be something as stupid as a bad pcv valve

 

i just noticed your sig, is your car turbod also?

 

the last motor was, not this one, im just trying to get this motor running to be ready to get boosted

 

that rules out the turbo or return line then. do a leakdown test if u have access to a leakdown tester and replace the pcv

 

oils black waters/antifreez is whitesh

 

Yea man im thought the oil burning was a blueish white color, and my pcv valve isnt hooked up to my intake. could it still be the problem? thanks alot -Ben

 

looks like u got a beater motor
