Initially, you'd have probably been better off with just 4 new bolts and NO gasket. The gasket allows for some movement, flexing, etc. It eventually gets blown out (depending on your system's backpressure).whistle87:
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
Once that happens the bolts no longer have any clamping force and can easilly back themselves out.
