no matter what i do i cant seem to keep my DP sealed.when i first bought the car there was only one bolt holding it on.took the turbo off,drilled out 2 broken bolts and tapped all the holes,made my own gasket and put locktite on all 4 brand new bolts.month later i have lost one bolt and the rest backed off.and blew my gasket out.how the hell are u supposed to keep this thing sealed?since it is a 3in. DP,all i can get on the flange it those allen head bolts
Do you have the exhaust hanger in place at the trans mount. If not most of the exhaust system weight pulls on the downpipe and elbow.
This will loosen or snap the bolts over time.
