HELP! Why are my new turbos smoking???

**hitman17** · 11-29-2010, 01:57 PM

Ok so I have two newly rebuilt 13G turbos. I primed them first by pulling the ECI fuse then cranking the engine 5 times, let it sit for 10 minutes, crank again 5 times, let it sit for 10 minutes, reinstalled the fuse and started the car. After about 2 minutes the turbos started smoking. Why in the world would that happen to newly rebuilt turbos??? All the oil and coolant lines are hooked up properly.

It's blowing white smoke, that smells like exhaust. This is just at idle, I haven't even opened up the throttle yet.

Any ideas???

I have doubt it is your turbos if you are smoking at idle.

Is your car up to operating temperatures when you are smoking and is your car smoking at idle after you have driven your car around? It might be your VSS.

My car is up on jack stands, so there isn't a whole lot of driving being done. :-). I was actually bleeding my brakes, and I notice smoke coming from the turbos.

My oil pressure is around 60, the temp if I remember correctly was around 120. Took about 2 minutes at idle.

Correct me if I'm wrong, but if it was my VSS wouldn't I be blowing blue smoke out the rear of the car?

Did your old turbos blow? If so it's probably the old oil burning off in the exhaust.

I would get the car drivable and drive it around for 30 mins then see what kind of smoke is coming out of the exhaust.

Blue smoke looks like white smoke to me. :P

Sounds to me like old oil being burned up mixed with condensation.

Yes my old turbos did blow. At least the rear one did. But now it looks like the front one is smoking more. Would the burning oil burn white? Would it smell like exhaust? Rough guess, how long should I let it run to burn it off? There may not be a good answer, but I figured I'd ask.

More often than not it's a broken ringland on a piston.

Pulling the plugs and having a close up look will prove it one way or the other, which is what you should have done in the first place.

Disregard this.... useless information again. Please stop steve. Seriously. You are hurting our platform. I destroyed a ring land and it didn't burn oil.

Go drive it for 30 minutes with some good boosting in there. Most likely it is just oil burning off from working on it.
Turbos don't tend to burn oil at idle, unless something is severely wrong.

See. 5 pistons with busted ring lands, no burning oil or smoke. Steve's post is just fluff. Not even worthy of that. It's just crap.
