LOTS of oil in the pressure pipes.

[evanisonfire]

so i got me a Turbolife FMIC kit and im in the process of installing it. tonight i ripped of the bumper and all the old plastic pipes and as i was taking off the pipes i notices ALOT of oil in them. im sure the pictures speak for themselves... is this normal??

 

[evanisonfire]

also i should state the car has 108KM on it and as far as i know this is the first time the pipes have ever been off or anything so could that just be 108KM of mild blowby??

this can be 1 of 2 things. first off, and the one you dont want, is the oil seals in your turbo could be bad which would mean you need a new turbo. secondly, a weak point on our cars in the pcv valve. it just cant handle boost and because of this when you boost you presurize the crank case threw it cause it cant close and that pushes vaporized oil out threw the big vacuum line from your valve cover to your intake. its then sucked in by the turbo and deposited in your charge pipes if it doesnt make it all the way through your engine. i had oil in my pipes so i upgraded to the millenia s pcv but it still cant hold up but no where near as much oil as you. i also have a bad wga so i havent been getting on my car in a long time so my oil is gone. this weekend im going to try and rig a 96 supra tt pcv valve on my car. if i were you id try that and see how it works out cause you dont want oil filling up your pretty new front mount. you could also put a breather filter on your valve cover but with a bad pcv youll have oil coming out of the filter and spraying your engine bay. BUT, if you get no more oil in your pipes than you know its not your turbo. can also try catch cans too.

 

[evanisonfire]

well then it may not be the turbo becuase there was alot of oil in the intake pipe also so its like that pcv im guessing. and ya i was going to just put a breather filter on it i think

I have to agree with CVP on this one bro. A plugged up or defective PVC system can cause oil to travel up the oil drain line to turbo or the crankcase was pressurized sending oil to the intake and in the compressor housing. I would highly recommend removing and inspecting the intercooler and all plumbing if you haven't already and check your throttle body for more oil as well as the BOV and BPV. You might have to flush out the intercooler with some degreaser if needed but in my opinion it is your turbo and will need to be R&R'd. Good luck!

[evanisonfire]

well im putting on a brand new FMIC and brand new BOV so i dont care about the stock pipes and intercooler. but how do i find out if it is infact my turbo or not?? what can i do to find out forsure??

 

[cvp0917]

putting on a breather filter will keep oil out of your intake pipes if its your pcv valve but if you dont fix the pcv valve as well your breather filter will saturate with oil and start spraying oil all over your engine bay because the crank case is still being pressurized. if you remove the possibility of the crank case oil from getting into the intake pipes, either by breather filter, new ungraded pcv valve, or both, and you still have oil in the intake pipes then it is your turbo because those are the only 2 ways for oil to get in there.

 

[MANDO]

Oil is not supposed to enter the compressor housing, especially in the amount shown in your pics unless it's the common small amount of blowby which in your case has definitely exceeded that. I personally would not run that turbo with a new intercooler.

 

[MANDO]

The pics show it all bro. Theres way too much oil in that turbo to continue running it. I have experienced a similar situation with my turbo as well. Trust me it sucks.

 

[evanisonfire]

but could that just be a mild amount of blowby that has been happeneing since 03?? cuz some of it is so hardened on its like mud so it must have been there for a long time

 

[carbonkid]

Can u repost pics? Are they working for anyone else?

 

[Wagonbacker9]

is there oil before the turbo? if so, its not coming FROM your turbo... if your intake is clean, your turbo is leaking oil, if theres oil on the inlet side of the turbo, its the PCV.

 

[evanisonfire]

there IS oil in the intake also yes but not near as much as in the pressure pipes. thats probably becuase the turbo sucks it all in eh??

 

[aubrandb3]

It sounds like a lot of blow by to me. That sucks, i had the same problem sounds like you are in line for a compression and a leak down test.

 

[Wagonbacker9]

yeah, doesn't sound like the turbo if its in the intake as well, but that doesn't mean you're outa the woods... so do a leakdown and listen from the valve cover breather... if you hear air escaping, start thinkin about some forged parts.

 

[neox.286]

sorry to say it but this is NOT your PCV, this is your oil seals going out in your turbo

it IS normal to have a small coating of oil in your intake and intercooler piping, but if it is dripping out to that degree there is a problem with your turbo's seals

you can replace the PCV, that's not a problem and would actually be recommended, but get prepared to have a much larger expense because that will not resolve your problem...or it will just prolong the inevitable for a few weeks at most

 

[aubrandb3]

The problem that you are describing is exactly what i dealt with a few years back. Does your car idle rough? You really need to do some tests i am not saying that it can be your turbo seals. Although it sounds like blow by to me. Take your oil cap off with your engine running and if you can see a lot of pressure / steam escaping then you can narrow it down.

 

[neox.286]

ehh, I wouldn't take the oil cap off while it's running for long

a better test of that is to just unhook the hose from the valve cover (on the driver's side) to the intake...but not sure how that is really going to tell you very much, as the pcv could cause a little back pressure to the turbo but not enough to put that much oil in the intercooler piping

 

[Wagonbacker9]

just do a leakdown test. if it holds, you're good, if you hear it leak out the crankcase vent its your rings, if its leaking out the TB, its intake valves, if you can hear it at the tailpipe, its your exhaust valves. if its none of the above, you likely blew a HG, but i don't think thats even remotely the problem here.

 

[neox.286]

ehhh, I think you guys are forgetting something

a blown head gasket on a turbocharged car puts oil out the tail pipe, not the intake

the exhaust manifold blows past the turbocharger's expeller, or hot side...not past the impeller...he would first have to have blown turbo seals to get oil in the intake side if he had a blown head gasket and he would have other symptoms as well with a blown head gasket...such as oil levels dropping dramatically, misfiring, stuttering, bad idle, etc...etc...
