    Hey guys ive got alittle problem going on with my t28 turbo blowing smoke sometimes.. I thought it was turbo seals but it doesnt happen all the time..
    If i were to leave the car there for 3 mins idling after warm it will start to pour out white smoke and then go away in 20 secs.. I am trying to work out if its to much oil in the sump for the oil return or seals are going.. the turbo drainline is 13mm . Noted turbo still boost sweet my last turbo also did this but not as often.. any ideas?

    start by taking the intake pipe off the turbo inlet and check for oil pools, if u have oil sitting there then turbo seals are shot,

    this might be a silly question but is the restrictor still in the oil feed on the turbo? assuming its ball bearing your turbo should have this restrictor. without it, the turbo see's too much oil pressure (bush bearing turbos dont need the restrictor)
