    So after getting my boost problem all fixed and using another turbo, I find oil in the Intake, when I mash on the car cloud of white.blue smoke comes out only Under boost. other than that its fine for DD, anyways I dont have the breather connected to the intake anymore so its oil coming from the inlet of the turbo. yes I see it and feel it when I take the tract off. Anyways can the pressure from my feed line (connected to the oil filter housing) cause the oil to spray through the seals? do you think it will stop if I refeed it from the head??? Thanks

    btw no shaft play.

    I believe its normal to have a small amount of oil in the intake, but how much oil you think its coming out? maybe check the intercooler for a buildup of oil in there.. I'd imagine if there was a lot, it could also reduce the effectiveness of the intercooler and lead to other problems.. just a thought

    Maybe take a look in the downpipe for fresh oil there also.. I suppose oil could leak out the turbine shaft seal and make smoke also.. boost pressure in the crankcase could push the oil past the seals and get burned up in the exhaust.. I'm not an expert but these are my thoughts.

    are you running just a line from the oil filter housing, or do you have a filter/regulator on it?

    Poor crankcase ventilation as well as excessive incoming oil pressure will both result in too much oil being held in the center housing of the turbo. Failure to repair this will eventually ruin the journal bearings.

    It's much more common for oil to blow past the turbine seal and into the exhaust than through the compressor seal and into the intake as the thrust plate prevents high pressure oil from being sprayed directly at the compressor collar. I'd imagine the smoke you're seeing is a result of oil being burnt on the turbine side more than the compressor side.


    Moving the oil supply to the head using a 1G oil supply line will most likely remedy your smoking issue as this is the line and oil source that the TD05H center housing was designed to be used in conjunction with.

    I have. ss line from the turbo to he oil filter housing, also my head isn't capped off the breather valve is routed to the port on my tb itself , two ports are capped off the P is used for my boost gauge and the E??? Is connected to the breather on the head..... Yes I have some oil in my ic pipe but then again if you look at my old post my turbine in the exhaust side blew and oil was eerywhere, this is happened on this turbo and the previous

    btw I see the smoke coming out of unde the hood as well when mashing on it. Smells weird

    Sounds like the turbo is pooping the bed and on it's last days like mine.

    Why are you bumping if your oil feed is still at the filter housing?
