So I haven't been on here in a dog's age but long story short I originally had a trackforged kit on a built motor. When I went to get tuned I had a bad coolant issue. At the same time I was considering buying a house and started parting the car out of course I couldn't give up the s2k so got it back together and put 1k miles on the built motor running it NA on the stock computer and it ran perfectly(last summer). Over this past winter I figured why not throw the turbo kit back on since I still had it. So recently I got the whole car all buttoned up and finished, starts up and idles perfect but I cannot drive the car cause once any load is put on the motor it goes lean (I bought the aem off a member on here with a similar setup but I know there never all the same and wasn't planning on actually driving the car until it was tuned). Here is my dilemma when warming the car up I get a very faint smoke that resembles condensation evaporation, once the car is fully warmed up it still smokes for a few mins and completely goes away. But When you free rev the car after every time I let off I get a puff of blueish smoke following. So initially I thought it was the turbo since I had no smoking issues prior to putting on the kit. So I checked the downpipe and exhaust housing when both cold and after it had been running and I found nothing, no wetness or anything resembling oily sludge. My next thought is that perhaps it's the valve seals but in the back of my mind I still believe the crappy precision turbo I have is causing the issue. Anyone have any ideas or insight on what it maybe? Could the turbo be burning oil and not leaving any residue if it's a minor leak? I'm running out of ideas so I figured maybe Someone on here may have a idea

 

A turbo burning oil would be white smoke.. Not blue

 

Incorrect. Smoke from burning oil always has a bluish hue. Coolant will produce white smoke, and excessive fuel burn off produces black smoke.

Precision turbos will almost always require a restrictor in the oil feed line. Where is your oil return located?

 

Yea it's white smoke with a blue hue, it's deff oil. I have the restrictor trackforged supplied with the kit. My oil return is in the girdle and the return coming out of turbo is straight up and down and the hose has no kinks or flat spots so it's deffinately not backing up there.

 

Have you driven it far yet? It could just be burning off stuff from sitting around for a while

 

No I havent since the cars goes lean and is untuned, I'm going to check the oil level later and see where we are at with that. Has anyone ever seen a turbo burn oil without leaving residue behind?

 

I'm assuming it would take more than some slight idling and revving to produce any sort of noticeable residue. That kind of thing usually takes time to build up.

 

Finally pulled the ic hose off the compressor housing and guess what I found in it and the ic piping, oil all over. Hate this car I have 2 choices sent to get rebuilt or get a borg ot garrett. Happy I found the issue but it just puts a damper on everything

 

Don't hate the car, hate precision, lol. That sucks man, perhaps try a smaller restrictor?

 

Brand new turbo? What a piece of junk
