I finally got everything working - no leaks - no problems, so far. (*I do not have a downpipe made yet) I haven't taken it for a drive yet because I'm running stock injectors. When I started it up at idle it was fine, no smoke, then when I rev'd it to about 2500 a few times, I was busy watching my tach and when I looked up, quite a bit of white smoke was emitting from my bay. I'm assuming this came from my turbo manifold because I have no downpipe and its raw exhaust? When I killed the car to get out and take a look, it was rising up through my entire engine bay so I couldn't tell its point of origin. Is it normal for a setup without a downpipe to puff white smoke? Could it be because I'm running too lean or an oil problem?

 

Probably spitting out a lot of fuel.

No Primary O2 sensor....

 

Is the turbo new? Might just be spitting out some residue from assembly.

 

what i did with my test run. i attached the o2 sensor to the outlet of the turbo with a coat hanger. lol

it worked!

 

I'm pretty sure it's just residue burning off. Give it about 10-15 mins of light driving and it "SHOULD" be gone. Double check all gaskets and oil line fittings.

 

OK well it still smokes like a ************ off and on. Sometimes it stops and doesn't do it at all until I stop somewhere and leave the car off, then when I come back and start it, it will smoke for like 5 mins then stop. No oil is in my intake pipe, and all the smoke is coming out of the downpipe outlet (I dont have my downpipe on yet). I think maybe there is some internal leakage inside the turbo housing? Is this anything I can look at myself without ruining the turbo?

 

Also, I think maybe my return line is too small. It is the same size as my inlet line which I think is 1/2 inch in diameter. Is that a bad size? Should I make the oil pan's inlet nipple bigger also? It's smaller than 1/2 inch. Typing that out, it sounds retarded, so I guess I will go get that fixed.

 

from my understanding, the oil drain should be a lot bigger than the oil feed. One of the main reasons is that the oil feed is pressurized where as the oil drain works off of gravity. If u don't have a sufficient diameter for the oil to drain, then the potential for the oil to get backed up into the turbo and leak past the seals becomes more likely.
