Default Turbo's leaking oil!!! Please help!!

After installing my twin turbo kit, my turbo's are leaking serious oil out the tailpipes. The turbo's are brand new master power t 70's. Anybody know what's happening?

I'm thinking either you have a restriction on the return or your turbo's or th seals are toast. This is a front mount system?? If so, they should gravity drain back to the oil pan with no problem.

It is a top mount setup with the return lines draining into the top of the oilpan. Why would the seals already be toast in these turbo's (there new!!)

I have used master power turbo's several times without any issues. I would check your drains. What size is your drain line. Also what size a/r are you running on the hot side? keep us posted.

I bet you need to put restrictors in the oil feed lines. If you're running a PTK type set-up PM Nick Yoskin as he has a lot of experience with these set-ups.

I agree with above -restrictors. Every turbo kit we build requires some sort of restrictor for the oil feed lines.

I was'nt running a restrictor on the turbo's upon masterpower's request that they will hold up to 80 pounds of oil pressure. So i then put a #35 nos jet in the line before the T and still had drainage issues of oil out the tailpipes, probally cause the seals had already blown out from no restrictor. I am running #8 line with a smooth return flow (I Checked) and Master Power said that was my problem, I should have used #10 (not much bigger) So I pulled the turbo's off and sent them back to Master Power to find out what the problem is ? I just hope not to install them upon return and have the same thing happen, any suggestions. Thanks for everyones help REALLY !!!!

That all that I thought was wrong with them. I have used them several times with no issues. When you say #10 line do you mean -10 line? Hope everything goes well with the new turbos.

You should also confirm that you are not getting any pressure in the crankcase. Even a good gravity drain won't drain very well when there's positive pressure in there.
