I looked around and there wasn't many threads about it. But basically I was running no filter for the longest time, and also through winter which i drove a few times when it was damp. Anyways. One day I was under the car and looked up at the turbo inlet and all I could see was black. WTF? So I go up top and look and there is black on the other side of the inlet too, I find out that the entire inlet is covered in this black crap. I figured over winter and what not it picked up debris and whatnot which was damp and just clung to it.. so I wiped it down and put a filter on it.. Now today i was searching it again, and some people say a LITTLE bit is normal? But then some said it was blown seals. I do not burn any oil or smoke any oil for that matter. So If the seals were going, I would imagine I would lose oil.. Unless it only went on the compressor side and it's leaking everywhere and prolly even into my charge pipes... Safe to say my seals are going or? Turbo is a Precision SC34 with about 7000Km's. I'm taking everything out tomorrow to get ready for the new setup so I'll find out tomorrow if there is any oil sludge in the charge pipes. Any insight before then would be appreciated as it'd be easier to replace the turbo now then anything...

****. Took everything off today. the charge pipe elbow right off the compressor had a decent amount of oil. further down like teh IC, the oil wasn't there. i guess there isn't enough blowing out to travel to the TB yet. oiSome oil at the downpipe too. and rememebr how I said the inlet had oil and I wiped it off. It's there again and even worse now. Now I needa new turbo ****. the turbo return line was PERFECT too. wtf...

Restrict the feed line more. You really don't need much oil flow, unless you are relying on the oil for cooling.

Well I'm runinng a 4AN line with a restrictor that I bored to 3AN size. I thoguht tht'd be about good. I took the compressor housing off the turbo today. OMG it's terrible.. I can't believe this...

If you're not burning oil and there aren't any problems with it, put a filter on it and run it into the ground.

I have a restrictor that is only 1mm, and my -3AN line is a stainless brake line, which has a tiny cross section. I still get enough oil to the bearings. I'm serious when I say they don't need much flow. Just replace the seals, clean the thing up, and run a better restrictor.

Tchleung

yeah it is strange. I don't burn any oil. and also the oil in the charge pipes only go abotu 1 foot before the oil residue starts to disapear

So you're running a 3an line with a .060" resistor? What kind of turbo are you running, I was thinking about doing the samething with my new turbo but I was afriad it might starve the oil to the turbo.

How long have you been running the oil lines like that?

dustin

I had this happen with my old drag kit. The turbo is getting too much oil pressure.

That is, if I am reading your post correctly.

yea, it could just be excess pressure bleeding through the seals

Tchleung

i'm just gonna clean the comporessor hosuing up and run a proper restrictor and see if it helps any. Hopefully the seals aren't completely gone yet

Tchleung

And no, I am running a 4AN line tot eh turbo, then at the turbo there is a nitrous/fuel restrictor that I bored out to the size of a 3AN line. I guess that's too big cause 3AN is about 1/8"

MDP

Definitely looks like to much oil pressure. Just clean it up good and make sure you use the proper restrictor and you should be ok....if your seals aren't blown completely.

Boltz

Sorry for hijacking your thread. but,

Where can I get an oil restricter for a precision sc32?
Like the deal that goes between the turbo and oil line, to minimize pressure on the seals
My oil feed line is big enough to hold a full oil change

I jsut got an autometer fuel/nitrous restrictor and bored it uot as it comes with like .5MM hole.

b18bturbo

have you considred talking to precision and getting them to check it under warranty they doe come wit 12 mo 12k mile warranty

Tchleung

Yeah I am gonna check soon. I'd rather jsut try a proper restrictor hole and see if it still ahs a problem. if not. yay for me. less hassle.

EJ1 wilcox

That's weird man... I thought that precision turbos had internal oil pressure restrictors?

That's just what I heard, could be wrong...

Hopefully your turbo isn't too damaged and the oil will stop once you put a restrictor on there...

Me too man

To my knowledge, PTE turbos don't come with built in restrictors

adictionbass

anyone know what turbos DO have a restirctor? Garrett t3 60-1 hopefully

.48 T3, for about... 2 oil changes.... need another... So about 10,000 miles now. Not only is the turbo spinning like a champ, but the turbine is actually much cleaner than it was when I got the turbo off a junked Mercedes...

BTW, I had similar problems to this when I used a TD05, but not because of excess pressure. Turned out the 1st Gen DSM BOV is open during idle, and there wasn't any backpressure in the charge pipes when idling to keep the oil from slipping past the seals! So a small amount of oil was getting in the upper charge pipe.

_entropy

It's your line, for sure. I'm running a -3AN line with a .055 restrictor, and it runs like a champ.

Tchleung

Well I alreayd ahve the 4AN line with my oil psi sensor inlnie so all my fittings are 4AN alreayd so I dont' really wanan cahgne it uot for 3AN. I'll just get another restrictor and make sure it's smalll
