I just removed my compressor housing from my turbo and noticed there is a small amount of oil in the compressor housing. Very small

But There was no oil in the piping, not a stain of it. confused.gif

I did not notice any on the exhaust side although I never removed the downpipe. But I didn't notice any blue smoke from the exhaust nor did I notice and significant amount of oil lost on the Dipstick.

Turbo has no shaft play.

I was boosting on this turbo for about 3 hours @ 15 psi. So if the seals were shot on the turbo wouldn't that be enough time and enough boost to blow the oil out in the piping?

Maybe to much oil pressure?

I am not using a restrictor but should not need one because my oil feed is from the Head and I am using a 1/8th feed line.

Whats your thoughts?

 

Seems like you've got a good handle on it though.

I would say oil pressure only because I don't know what else it could be. It could be just a tad high, but not high enough to cause a blow out of the seals. Maybe double check that. Otherwise I dunno. If it's in the compressor side you should see smoke or something. Unless it's such a small amount that it burns with out it showing.

Only thing I'm thinking, and this is worst case, is that the turbo has a bad seal on the compressor side and it is allowing a small amount to push through.

 

^^^ Yeah I am thinking oil pressure as well. I am running an oil pressure gauge but I taking the reading from the block. But even still I cant see there be to much pressure coming from the head

For those running an oil pressure guage up from the head how much oil pressure are you getting going into the turbo? Did you have to use an oil restrictor?

 

Well there shouldn't be too much difference between where the gauge is and the turbo. I've been out for some time now with the turbonium so I lack the troubleshooting knowledge, but I'd start there. Beats tearing your TC apart.

 

Ok I am starting to think its the my oil return causing the problem mad.gif

Now I Have the return spot in the pan the same way for the past 2 yrs on m other setup and never had a problem. But with this seteup the turbo sits lower and return line had to be shorten and it there was no way to makea Direct straight down dump it had to come in on a slop like Mad-Jons setup.

And from what I can remember correctly ,,,again this was 2yrs ago when the pan was off for the bung to go in this was the heighest this could go up from the inside....then again it was 2 yrs ago





Here is the way my oil return line comes in..Not the greatest I know...but what am I suspose to do?

 

Ouch that is a little rough. It seems like the oil may just stay in the return line as there is nothing but gravity sending it back to the pan.

I suggest maybe a little bit larger return line, and making sure that it goes directly to the pan. Looks like there is a little bit of a droop, or up-turn in the line. 02.gif

My only other suggestion is to spend too much money on a oil cooler/pump assembly. Pain in the @$$ mind you but temps would not be an issue.

 

I agree it looks like the drain. I had the same problem it was angled weird and resulted with some oil in the compressor the seals are probably okay if it was for only for a short period of time. The turbo will probably still be okay as long as you correct the problem the seals will just we worn a little.

 

sorry for my ignoration...but....

the place where the return oil line, in the pictures above go , is good? or can to put it in another side?

 

^To do it right, put the return right into the block, not the pan.

but.....where? in what part of the block? can someone put photos of where will be the return oil line in the block?
