Turbo Oil Feed Regulator needed with my Precision turbo??

[jdpolzin]

I'm at wits end with this. My Stage motor has a high vloume front cover, 70HPQBB Precision Turbo, a turb saver kit with -4 lines. I dont think Precision quite has there restrictor fittings figured out for those of us who run good oil pressure. I'm getting oil into my IC pipes. The car hasnt seen more than 8psi of boost, which really doesnt matter anyways. It also has basically no miles on it. I drain back to the pan and have checked for flow capabilities, checked to see if I have too much oil in the pan that may block the oils ability to return. Everything is good. When I bought this turbo and saver kit, Presicion didnt supply a restrictor fitting with either, I talked with Pete and ended up having to buy one. So it's been on the turbo. I dont know what else to do aside from puting a regulator inline from the saver kit to the oil feed. Anybody else have to do this? What pressure are you restricting the flow to the turbo? I'm tired of leaking oil all over my new beautiful Stage motor. ----Jeremy

BTW...It's not smoking out of the exhuast, just leaking into the compressor side and into the IC.

When I put my 6262BB turbo in my car I had the oil going in my downpipe, called Patrick at Precision and he told me to put a .30 NOS jet in the restrictor fitting. Give Patrick a call to see what the smallest jet you can use. Tim

Yeah I'm going to have to do that. I'm seeing restrictors on ebay that range from .03 to .04.

I have one of the first turbo saver kits that came with -6 line. Needless to say I had oil going past the turbo seals. I tapped the AN fitting that screws into the turbo for a set screw then drilled a .100-.120 hole through it. It helped tremendously. I do have a journal bearing turbo and didn't want to go too small. Not sure how small how you could go with a DBB turbo. Hope this helps. Jeremy

I got it figured out finally. What happened is, Precision never sent me the restrictor with my turbo. So when i ordered one, they sent me a regular adapter instead of the restrictor. I wasnt sure what size the retrictor was supposed to be so I thought it was the correct one and have been fighting this the whole time. Well, after a bunch of phone calls and oil caked all over my brand new ceramic and pollshed stainless exhaust parts, all over the bottom side of my freshly restored car, oil all over my brand new Stage motor, I finally got the answer i needed. This time I just bought the restrictor from Ebay so I dont risk getting the worng thing again. I got it in the mail yesturday and will probably be able to see how it works this coming week. Now I'm going to have to spend a few weeks trying to clean this damn mess up.....YAY!!!

Well I'm a dumb a$$, I went in there to change out my restrictor only to find out I already put one in the damn thing last fall! I totally forgot about that. Good and bad, problem isnt going to be solved. it's still leaking into the IC so I called Patrick today, who was very helpfull once again I might add! He pointed out one thing to me, since I'm running TA Valve covers, the grommit in the breathers are restricted by the baffle. This could be my problem since they dont allow crankcase pressure to release through the breathers as effeciently. I'm also running a PCV valve, which could also be a culprit. So one step at a time, I cut the baffles out of the breather grommits and I need to find a plug for the intake. We shall see if this fixes the problem. I also re-checked my drainback, which drains into the pan. I undid the AN fitting and left it loose. Check oil to make sure it is full and it was. I jacked up the rear of the car to see if anything dripped out of the bung welded in the pan and got nothing. The actual drain back AN hose is a -10 with a 45deg fitting at the turbo, it then wraps around the turbo saver adapter on the front cover into a 90deg fitting and into the pan. Looks to me like it should cause any restriction. What do you guys think?

I used to have a thread in here about a similar issue but smoking, went to a -3 brake line and stopped the smoking. Stock oil feedline ID is a hair smaller than -3 if I remember correctly so it's all good.

RJC Racing in Salt Lake City - sharp buick turbo guys have a brass pvc with viton seals, it stopped all the oil coming out of everywhere on my freshly restored GN with a TE-44.

Will be tested on this years power tour, planning the long haul.
