Well, last night my buddy and I fired up the car just to listen to it and heat cycle it a bit because it hasn't been brought up to temperature in a little while... I had noticed some spray that just looked like carbon on my motor... I had an exhaust leak... didn't think anything of it...

Now I noticed yesterday when I drove it to and from the exhaust shop to get the downpipe put on, I got on it, and saw blue smoke behind the car... which means oil... Now it was a fairly decent amount of smoke, but not as bad as when my buddy blew the shaft on his turbo and locked it up...

Anyways, my buddy said to me that he thought he smelled burning oil coming out of the tailpipe... I had noticed it too, but didnt think anything of it, figuring it was sludge still in the downpipe... I pulled the downpipe today, and it looks like THIS

Oil on the exhaust side but not the compressor side... This began to worry me.. This meant

A. Blown Rings,
B. Blown Exhaust Seal
C. Bad Oil Return Line

So I pulled my plugs, and phew... No oil on them... Just alot of CARBON...

Now I know i'm running REALLY rich... Gotta burn a better chip.

Then I was thinking bad Oil Return Line. So I stared at my return line... Looks fine as far as I can tell.. I even went as far as to pull off the Heat shielding from the oil return and put it back on to make sure it wasn't kinked... As you can see, it isnt.. Now in that pic, it looks like the return line comes up... It doesn't... Its consistantly downward into the pan.



So now I'm thinking either 1 of 2 things..

#1. Blown Exhaust Seal...
#2. My Feed line is a -4an feed line... My return line is about 1/2" OD... Now I'm thinkin that my return line might not be big enough, and i'm putting WAAYY too much oil into my turbo... I was thinking put a restrictor in-line to reduce the oil flow to the turbo. Do you think that would help? I know that turbos don't need ALOT of oil...

If its an exhaust seal, how hard is it to replace? What is involved? Will it be visibly noticeable? Is there any way I can check to see if its blown without pulling it apart? I was thinking pull the fuel pump/ECU fuse and try to crank the car over so it wont fire while I leave the oil return line in a soda bottle so it will fill with oil... And then checking to see if all of the oil goes into the bottle, or if some comes past the exhaust seal... Think that would work?

I have not driven more than 3 miles like this... I haven't driven more than 3 miles sincei put the turbo on my car... The turbo was VERY CLEAN when I got it. So I doubt it was blown then. I bought it from a well known member of this site.

TIA

 

anybody??

 

Dont worry everything looks and sounds normal. Turbos naturally burn oil and a little more oil in the turbo doesnt hurt anything. You may get a little bit more smoke but thats it. My car sends out a nice cloud at 8 psi or higher. I boost 14psi daily. When I see it, i know the turbo is getting the oil it needs. Check the blades and housing to make sure they havent been grinding against each other and thats all you really should care about. From the pics it doesnt look like it. The compressor side may be easier to tell though. If so it may need a rebuild.

 

but there is ZERO oil on the compressor side... Do you think I'm pushing too much oil? Would it hurt to drop the pressure with a restrictor?

 

The compressor side is not supposed to have oil. The excess oil is supposed to go out the turbine. Restricting the oil would hurt the turbo more than it would help.

 

have you checked to see if you have any shaft play side to side?

 

a 4an line will hurt ya in the long run...and it kinda looks like you have a little kink in the drain line (picks of the red hose).I would get a 3an line on it and try and get that drain a little bit more opened and it should be fine.also what oil are you running? the blades on the turbo look dry so its kinda hard to say what its from..most the time a turbo with a bad exhaust seal has a compleatly wet turbine wheel and housing.

 

a 4 an is what I and most people use. It will not hurt a bit.

 

also with your plugs looking like they do it could be due to condinsation (sp?) and fuel mixing and buring off old stuff in the turbo/exhaust. (ever see what drip from a exhaust pipe in the cold?)

 

Take a look at your coolant level,and maybe drop some oil out of the pan.The oil looks very gray.This may be coming out the exhaust,not the turbo.Blown headgasket?

nah... checked that... oil is clean... Plus if it was a HG, it would usually show up on the plugs wouldn't it?

I'm running Mobil1 Synthetic Oil 10w30.

The thing that looks like a kink in the return line is just the insulation... the insulation is larger size than the hose I am running... The hose itself isn't kinked...

And as far as the plugs go, I have been noticing some condensation on the plugs, and obviously, they smell like fuel...

I'm on my way to the hardware store to go get new bolts & a m8 tap... Somehow I managed to strip one of the bolts.. How I have NO IDEA though... Then I'm putting this ****** back on and driving it...

 

its blown. **** it. Winter is here. Car is done. **** it all.

Put it back together, started it, and it was SPITTING oil out the exhaust... pulled the downpipe AGAIN and the exhaust wheel is SOAKED... So winter is here... Time to rip apart the car and redo the entire i/c piping, rebuild the turbo, 3" downpipe, 3" catback, and all of it.. **** the bullshit... Big Baller time.








^^^^^^^^^^ Thats me giving the finger

Is your intercooler full of oil too?

didnt even check if its going that far yet... I doubt it... Its ALL exhaust side... i'm running a screen for a filter, and i see nothing on the intake.

time for

 

seal between the bearings on the exhaust side is worn thin thats why the oil is seeping, may also be the c ring that is at the very end, buy a rebuild kit for your turbo and that should fix it, or run thicker weight oil so it wont seep through

 

The easy way to see if your exhaust side of the turbo is leaking oil,
is to simply let the car idle for a good couple minutes. If it starts smoking like a pig
after a few mins, you found your problem.

 

oil in the intercooler pipes?

Do yourself a favor and do a compression test, 15 minutes and youll know a lot more about the state of your motor.

no oil in the i/c pipes... Car is coming apart for winter... motor might be too...

 

good luck with the car..and if the turbo did go south let me know..I will help ya out with it.
