Smoke after Turbo Swap! Please Please Help

[lewishamilton]

I'm getting a moderate amount of white smoke from under the exhaust manifold on my first start of my car after switching over to the 14b. How can I tell if this is PB Blaster or something burning off, or something to worry about?

It could be something burning let it run for a while then youll see.

Let it run. Whats it smell like?

 

[lewishamilton]

I just let it run for about two minutes and the smoke started back up. It doesn't really smell like oil or coolant. Just "engine smell" and there's a small bubbling of fluid on the leftmost exhaust runner on the manifold.

Ps turbo was freshly rebuilt by justin.

It'll burn off for a bit. I wouldn't worry about it unless it was smoking out the end of your exhaust. Oils from your skin, oil, coolant, lube etc etc get a small film on the hot parts and it burns off.

I think the last time I had my turbo off it smoked for about 5 min as it was heating up.

I always have smoke and a burning smell after swapping turbos/ exhaust manifolds. Although this is normal from all the stuff that got on it burning off, make sure you also don't have any of your oil or coolant lines leaking befor you go for a drive.

Just drove it and I'm getting generous amounts of blue smoke in boost and it was stalling as if I wasn't recirculated (boost leak?)

Where is your oil feed for the turbo? From the head or ofh? And its a good idea to do a boost leak test after changing any parts related to the turbo and intake system! If your last turbo blew it could be left over oil and stuff from that.

Oil Filter Housing. And yeah, I'm seeing that that's necessary now.

And yeah the T25 left a lot of oil, so I tried to do an extended test drive to try to burn it all up, but I was still worried

Do you have a restrictor inline? Running a 14b of the ofh would be to much oil pressure and push the oil seals out or allow oil to get thru. The 14b was run of the head in the 1g's and it's recommend to do the same on a 2g. Or have the proper restrictor in place so you won't over oil. Have you checked your line pressure to the turbo off the ofh? If it's left over from the t25 it could take a few good pulls to clear it all.

Is there a restrictor that would fit on the fitting I already have?

I was going to try this. Is there a good way to know whether the smoke is to be expected from the previous blown turbo or cause for concern? I don't have any way to measure line pressure off the turbo, and I'm still trying to get my oil pressure gauge to work.\


Edit: and the smoking under the exhaust manifold stopped btw. But now I'm getting white smoke at idle.

Its hard to say what size restrictor you need. I would ask justin for his recommendation! I know way back I installed a 14b on one of my 2g's and it smoked like crazy being feed from the ofh. I switched it to the head and a few pulls later no smoke and not one problem after that. For you its really hard to say if its from the old or new turbo sorry, but I suspect its an over oil issue! You really need to see what the oil pressure is and then get a restrictor that will get you down to where it needs to be. You also have no balance shafts and that will boost up oil pressure. Is your ofh ported?

I've since cleared out my inbox but I believe he said .070. I'm going to shoot him a message. Will over oiling it for literally less than 2 miles, and less than 15 minutes of total runtime cause damage?

 

[Mitsumungst-gvr4-tsi]

It's really hard to say. You risk killing the oil seals if you keep running it, and you might have already bro. When I realized mine was getting to much oil I got home fast and stayed out of boost and mine was ok. But I drove like around my block and that was it, from all the smoke it was easy to see my problem .
