Question need some advice

ok heres the deal im not sure if its my oil line under the turbo or what but there is smoke comming out of the tail pipe and before you say the engine is bad i just had the engine rebuilt so the engine is strong so my question is do you think its my oil line under the turbo or could it be the downpipe has oil that needs to be burned off?

Did you get your turbo rebuilt? (Or preferably buy a new or known good one?) Bad turbo oil seals could be your problem, oil leaks past the seals into the intake and then it burns in the chamber, making oil smoke.

I wouldn't drive the car until I took the hose off the intake to to turbo and verified that it was clean (no oil) and that there was not too much shaft play.

(Burning excessive oil=Carbon build up=siezed apex seal springs=blown apex seal.)

Someone may correct this logic, but that is what I have heard.

thanks i did get a good used turbo from a friend of mine and the shaft play was cool so im guessing that the turbo needs to be rebuilt then but it stops after a while it started today and then it stoped, yesterday i put a new gasket on the turbo oil line (the one at the bottom) and while i was doing that some oil driped but after i put the oil line back on i cleaned up and drove it around and let it run but no smoke and now today it smokes and then it stops after a while
