I called percision and they said do not put a restrictor in the feed line. I have a 1/2 hose straight down into jug two feet away and its draining fine. I hooked up the oil return pump and its pumping the oil right back to the front.

its dripping/pushing oil out the dp, and even when the jeep is off there is a slow drip at the exhaust v band

total idle time on the turbo is about 10 min.

Im calling the speed shop that sold me the turbo to see if he can over night me another one and ill send this one back to him.

FFFFFFFFFFFFFFF

 

Yeah, sounds like it might need a rebuild :/

 

It's brand new!!!

I'm gonna try a 5/8 hose from the turbo to the pump. Some people run a restrictor some don't. Precision said no.

I have a -4 feed.

 

I would contact Precision. But from what I've read on tech, apparently they will just tell you that your setup is wrong.

 

Low rear mount turbo?
If so did u install a check valve on the psi line at the turbo?

 

I had the same problem with my precision and after 3 rebuilds I got rid of it. Their cusomer service also kinda sucked.

 

I called this morning, they said put a bigger drain on it.

Yes, just like an STS kit, no i did not put a check valve in the feed line. Please explain why i would need one in the psi side, its always under pressure, pushing oil into the turbo.

Please pm me the total price of your 76mm journal bearing turbo over nighted to 14120.


please dont tell me that!!! what brand did u go with? He bought it before I met him, otherwise i woulda sent him to Rick for a master power 76mm.




This is the oil pump I have

When I get home, im gonna swap the 1/2 hose for a 5/8 from the turbo drain into the pump. if that doesnt stop it, Ill add a restrictor on the feed side ( popular like is .65 ).

My question now is, since it already sprung the leak, and wasnt a mist but a slow drip, is the turbo shot and needs a rebuild or if these two changes work, itll be fine?

 

Well that makes sense. I assumed it was a front mount. There is residual pressure in the line after you turn the engine off because the turbo is mounted lower than most/all of the oil feed line. Its just enough to seep past the bearings when everything is **** down and it collects in the turbine housing and exhaust. A 1 or 5psi check valve would work fine to keep oil from entering the turbo with engine off.

 

^^^^ exactly what happens

where do i get one? link pretty pretty please

 

Yep, every rear mount turbo NEEDS one!

McMaster-Carr PN 7768K51 should work
