milkman : coming to think of it again , I don't think the restrictor is a good permanent fix , rotary guys use them because their cars have very high oil pressure , I used it and it seemed to work for a while with no boost (I was breaking in the engine) but once I started putting boost , the burning came back . From what I understand is once you get oil past the seals of the turbo (it actually looks like a car piston) the damage is done and the seals have to be redone . I put a 40 shot nitrous pill in the turbo fitting and it needed some filing down first .
I DON'T recommend this anymore especially since it seems that the oil will still burn but maybe a bit less. too small of a shot can burn your turbo really fast , every turbo reacts different to this mod . If you attempt this , its pretty easy to do and I can take a picture of the fitting for you with the nitrous pill in there , but please do so at your own risk .
