smoke and oil leaking around turbine

[embler]

I had a major smoking problem and thought it was the seals. had the turbo rebuilt and put it on and it still smokes. I noticed that oil is leaking around the turbine where it bolts up to the center section. is there a gasket that goes there? any comments or suggestions? also, my return line is good. I tried a maxpsi one and I thought it was to small. I made my own. it has a 1/2" inside diameter so oil return shouldn't be a problem.

Maybe the old oil is still burning off.

I too am having this problem with my girlfriends car. The problem is driving her & me crazy. It started on a head swap. The previous one was cracked and the new one check out with the magnaflux test but the correct valve seals weren't installed. I thought we could get by for a few months but right on start up it started smoking. I'm thinking it may me the seals but I'm not sure. The plugs are clean but there's oil around the #3 exhaust port and it's not from the valve cover. The turbo also has oil around where the turbine housing bolts up.

Take it back to whomever did the work

I took it back and they took it part and rebuilt it while I was there. all was good with it. the guy gave me some good advice. I had my drain pointing straight down coming out of the center section. he said to **** it at an angle. example he gave was like when you pour a quart of oil in. hold it so its pointing straight down and what happens? it burps and you get a lot of oil out at one time and then it'll back up until it burps again. turn it at an angle and it'll flow right out with no problems. sounds logical to me. I have the center at an angle now. just have to find the time to bolt it back up and test it out.

This is truely a first for me (what I have seen and read)........I am curious to see how this turns out.

first for me also. the guys build turbos for a living and they seem to know what they are doing. they told me that they have a lot of guys come in like me that put on a new or rebuilt turbo and it smokes due to the drain line not being on there right. hope to finish getting it on today or tommorrow

finally got the turbo back on today. putting the drain at an angle let it drain freely. it smokes no more!!!

Interesting.... Must be why the OEM one is such a PITA....

Somehow this doesn't make sense to me.

When you're poring oil into an engine, you're creating a vacuum inside the oil can if you pore straight down, doing the angle thing allows air inside the can.

Inside the turbo oil system, that should all be pressurized.

My 2 cents....

X2 I agree

x3 but I didn't want to sound repeatedly argumentative (read into my post on #6). Cut a hole in that oil bottle while pouring and the oil will come flying out.

Additionally, any fluid (a gas or a liquid) will automatically want to flow to a lower pressure area.

I am going to have guess that by clocking the turbo you got lucky and sealed up the internal leakage, or maybe Mike is right. I say this because this turbo person's theory doesn't hold...well, oil.
Why have turbo manufacturers and auto desogn engineers arranged the oiling system directly vertical and not cocked for years? Not trying to bust your stones, but those of the guy who tried to sell you this story.

I can give you guys the name of the guy and place that told me the info if you guys would like to call and ask them about it. this places does nothing but turbos so I figured I'd listen to them and give it a shot. it worked so I could care less. navy, the only internal leak it was having was the oil not getting out fast enough and it was blowing past the gap on the ring on the turbine side. I work on diesels at work (internationals) and looking at them, none have the drain pointing straight down. all have it at an angle.
