A problem after another...I thought everything was all set after fixing the rest of the stuff...but now the most unexpected dilemna comes from the turbo itself. The turbo is leaking greats amount of oil from one of five bolts. I tightened all of the bolts but it still leaks the same amount. Could this be a problem from the bolts? I used a washer before the bolt but that didnt help. ive also used teflon but no change...any idea?
