As you can see there is oil in my compressor side along with oil throughout all of my charge pipes, (some I wiped away in the pic). I cannot figure it out. I feel I setup the oil return properly with a minimal flat spot.

I installed the kit 2 weeks ago and it's a precision turbo. Everything was brand new. Also, I'm ordering a better oil return line right now.

Do you think my seal definately blown? And what else could of caused this?

All input would be great. Thanks

looks to me like the oil return line is running slightly uphill which could certainly be a problem. it is a gravity drain oil return so it has to be down hill all the way.

unless the pic is throwing it off. after second look at your pic i'm pretty sure that it can't drain because it is going uphill.

 

You need to shorten your Oilreturn line on the turbo side to get rid of that uphill run to the oilpan. ALso you need to seriously think of running SS oil return line as that high temp Silcone willnot last long being that close to the DP. Im speaking from experience as a friend of ours used the same hose and it was almost meltd thru from the heat of the exhaust, It was wrapped in thermotec heat wrap as well.

 

yeah, that return is pretty suspect...

 

Thanks for the input guys. I just dis-assembled everything and put the oil return to the test. I poured oil in there at the same angle and it took it in (the car was leveled too).

I also took off the exhaust housing and compressor housing too see if anything is wrong. The gasket was there on the compressor side so not leaking through there..

Next, I put my mouth to the oil inlet on the turbo and blew air through it and it seemed very resistant. But, I can't see anything that is clogging it.

Is it supposed to be that resistant?

Thanks everyone

 

i would imagine it would be a little resistant to you blowing in there, there is a fan right there after all

 

It's probably resisitant from the oil that is still in there... (there's no fan in the cartridge)

I have to agree with the comments above, the drain didn't look like it was the right angle to properly drain the oil.

 

I did a little more testing. Is this normal?

I poured a thin line of oil into the turbo and it overflowed...after like 2 seconds... And it didn't settle down.

Is something clogged here?

Also, there is like a white residue mixed with oil that drips from the return of the turbo..

I need help...!

 

My oil return is worse, and I haven't had any problems with it yet. . .

 

what size is the feed?
it doesnt look blown yet..is it smoking..just could be leaking

 

Im also having the same problem. Whats weird is my return line has a nice height and SS from (flemenco-t) and medium oil level on stick, and the fact that, it gets oil all over the compressor inlet, but stop every now and then.

Pretty much it stop leaking and starts.. And stops..and starts...

WEird?

Bump for a useful thread I also need info on. and Nope Turbo does not Smoke.

( How bad does it smoke anyways when the seals are blown? Very noticable?)

 

I'm having the same problem as you....(no white smoke)

But what is white residue that's mixed with the oil? Coolant??

And any answers to why the turbo isn't taking in the oil?

When the line is hooked up, is it maybe forcing it in there and that is whats making it leak through the seal....(?)

 

That return looks fine to me

 

then what would cause this on a 2 week old precision turbo?

 

Perhaps the turbo was improperly assembled in the first place.

 

the return line looks a little long, but have you adjusted the oil pressure to the turbo??

my seals wern't blown, it was the stock oil pressure of the engine that was cuasing the oil to leak past the seals and cause the smoking.

a good oil pressure setup is around 5-10psi at idle (hot) and around 25psi at 3000rpm's
FYI my engine was doing around 60-70 at 3000rpm.

 

hmm... good point, though I don't have an oil pressure gauge, so I wouldn't exactly know...

what would cause the pressure to jump that high?

oh, and the feed line is a -3an (i think someone was wondering)

 

thats just how my engine is (D16a6)

turbo can run on surprisingly low oil pressure, and considering our engines are not turbo'd from the factory, the pressure needs to be adjusted to prevent smoking, or even worse a blown turbo.

was there any thread sealer (paste) used on the threads of the oil feed line entering the chra?

Well, the engines still need a lot of oil pressure for VTEC activation, but the turbo's don't need the high pressure.

 

bump... interesting thread....

i have similiar stuff out of the compressor inlet... very thin liquid... doesn't smell like oil nor coolant... checked the charge pipes... no oil there...

im not boosting... don't know what's wrong... check vacuum lines (pressurized the charge pipes and vacuum line... seems to hold)... checked wastegate... no boost..

 

nope, no thread sealer used...

it should "flow" through though right???

should I contact Precision about this?

I originally purchased this from camp1320, but it's nearly impossible to reach Tom.

 

check your oil level

 

My oil return is exactly like yours. I have a pte turbo also and my car smokes. The way your oil return is the only way to route it. It won't get any better. If you want a better drain you have to put the turbo compressor facing the driver side.

 

Well, I'm trying to rule out the possibilities...

1) the oil return may be the cause..so I am installing the ss line with the (2) 45 deg. fittings and hopefully that will give it a more straight/direct route..

If it still leaks through the compressor, then I will assume the seal is blown and maybe precision will warranty it...
