Smoke from mani
 

I have a problem, what causes oil to be burning off in the exhaust manifold and smoke rising up from it? I've had this problem for a lil' while now and I need to fix it.
BTW compression tests are good.

could be a seal in the turbo. mine did that too.

Well this is happening now and after I had the turbo rebuilt.

Re: Smoke from mani
 

maybe your oil drain is getting clogged up and causing the seals to go bad

Re: Smoke from mani
 

I like my oil drain though. It looks good enough to me. But would this cause the mani to smoke?

Turbo may be getting too much oil...try a restrictor

Oh yea? Post some pics of it so we can make sure it's as good as you think it is.

Yea, that doent sound very promising. Lets see a pic.

And where is this buring oil smoke actually coming from. You say the manifold and I guess I dont see what your saying. Is oil getting on the outside of the manifold and burning off. How long have you been running this setup? Or where exactly is the smoke coming from? the head flange of the manifold? the turbo flange of the manifold?

valve cover gasket? need more info/pics

When I start the car and when it gets warm light smoke arises from all over the manifold. Reminds me of steam sort of. When I run it hard and stop I can see it come out from under the hood. Also when I walk around I see it being pushed out with the help of the radiator blower fan. When I lift the hood open all I ever saw was it arising from the manifold AND the turbo. I knew the turbo needed a rebuild since it leaked a lil bit so I got that done professionally. It still smokes from the manifold and not the turbo now. I've had a oil restrictor running on the turbo since I've had pretty bad exhaust smoke. I have ran my car once since I reinstalled the rebuilt turbo since I noticed a humungous radiator leak. Other problems that I have that will be fixed soon is a rear main seal leak I have been having problems with too. I run Uberdata with a basemap with a ZT-2 wideband which is ----. I'll be getting a PLX here soon so I can tune her properly.

BTW, I've also always have had exhaust smoke issues. Compression test always work out too.
