Oil my turbo garret

[racingp]

Hello,

when turning on the bike the turbo spits oil on the side of aspiration as you can see in the video:

Install a suction pump and a small reservoir under the turbo thinking that it was the problem but keep doing the same

What could be the problem? How can I keep it from spitting oil? Does the turbo have a problem or is it okay?

The turbo is ball bearing

Thanks

Make sure you have a restrictor on the oil feed line at the turbo too. You running a high pressure pump? What kind of air filter you running, too small will blow that compressor seal with vacuum behind filter.

Exactly this...too small air filter will pull oil past the seals

Make sure your turbo is clocked correctly and all the oil is draining out of the turbo. If some is left in there, it Will Drip. Could have oil in your cold air pipe also. Mine smoked every so often until the oil got burnt out of the turbo. My return line wasn't angled properly out of the turbo into the pan. I was ready to pour gas on it! Sent it to Powerhouse. Problem solved. Just my experience with the Dbl. BB.Turbo I have on my Velocity system.

Mine did the same thing. Not as heavy though.

Ball bearing turbos require an oil restrictor. If you don’t hav one that could be you biggest problem.

thank you very much to all



Where can I buy the oil restrictor? What measure do you recommend?

Is your turbo ball bearing?

Nevermind, I re read and it is.

This will do the trick.

Hello,

Yesterday, check if the bike has an input restrictor and if a restrictor of 0.9mm is mounted, does it need to be smaller If so, what size would you put

Thank you

.9mm is .035”. That’s the smallest restrictor out there.

So either your turbo needs a rebuild, or it’s hanging too low that it’s not draining.

My journal bearing turbo is doing the same thing. I believe I have a restrictor installed also. Probably ruined it. Y having it on there. My leak isnt as bad as your but leaks none the less, atleast with the filter on

A restrictor on a journal bearing turbo will cause damage.

My bike may be a very special case but I had the same issue with a journal and bb turbo. Leaked because of a too small filter.
I'd just say at least give it a shot to eliminate.
I know 99% of the people running the stealth filter are fine. I was the 1% I had to have a larger filter.

I figured as much. I let it run in the driveway and no noticeable oil leaked with the filter off,maybe I need to put sustained load on it.. I'm going to double check to see if I did install a restrictor as i installed the turbo about 4-5 years ago and my memory sucks.

Another thing to remember with ball bearing turbos is they rely on shaft speed to seal properly. If the idle is less then 1300rpm, bumping the idle can help. But with how it’s leaking in the video posted, there’s something else going on.

You are So Right! That's my problem boosted. The early Velocity Systems hung to Turbo low. That doesnt give you very much angle to the pan.

good morning

I removed the conch from the turbo and re-tested and in this way no oil comes out.
