So, what turbo are you running? If it is a ball-bearing turbo, and you are NOT running a restrictor on the supply line, that will definitely blow the seals!

My gt35r was not clocked completely vertical. More like an X, with the oil and coolant supplies coming in at the top, on a 45* angle, and the drains draining at 45* from vertical/horizontal. I never had any issues with oil not draining, but I was also running a 3/4" drain line, I think....

its a journal. t3/t4 Precision 6031

I have wrote this in a couple of theads but it could be the restrictor, it can blow out the seals at start up. I am no expert on this but I was told to do a BB cause this problem can happen. You may want to look into that, it has been a pretty common thing with the precsion turbos. Maybe the Soprpion guy can chime in on it.

 

restrictors are for bb turbos not journal.
I have a jounral.

 

Are you sure, I am not the one to be asking but I was told this buy the guy I bought mine from. The S2000 has some pretty high oil pressure at start up and can blow the seals. Maybe people with more information on this subject can chime in.

 

He's only getting smoke on boost.... hmmm.

 

The Precision 5857 journal bearing that I just got came with a -4an restrictor.
Thats the same size as the feed line so it probably doesn't make a difference.

 

ya thats the plan, im going to call them tomrw and see wat they say...

 

What did Precision say?
My car is supposed to be on the Dyno today. I hope I dont have any smoking going on. The more I search, the more mixed info I get. Some say use a 4an line w/ 3an restrictor, others say .065 restrictor. Some say no restictor at all.
