Thanks all,
Ive had a look at most of the breakers and no luck so far, im taking the turbo off this afternoon but from what i can see so far the seals have failed as theres oil in the inlet side.
Bit of history on the car, i bought it as my daily driver as i have a skyline that ive rebuilt as a track car, the prevois owner had blown the bottom ends and cracked the crank, i managed to get another engine to drop in as i wasnt planning to push the bhp up to much other wise i would have done a full rebuild on the origional one, so far all ive done to it is new front wings, powerflex bushes, replaced the old ball joints and drop links,new clutch master and slave and full braided line,FMIC, SS manifold, hks filter, blitz boost controller,ebc brakes,new 52mm radiator and electric fans, ssqv bov,3" system ebow back,and a 255 fuel pump, the next job was the respray but thats on hold now till its back running right.
