Hello,
I am having a problem with exhaust leaks, I am, for the first time using copper nuts as opposed to the steel with insert and flange Porsche part # 039.256.297 see photo below. I would still be using these if I hadn't lost one, and Porsche says these are NLA. The procedure I would use, after replacing the copper seals, I would use Never Seez on the studs and torque the steel nuts to 16 ft-lbs. I am not sure if I should use Never Seez with the copper nuts and I am not sure the torque is correct for these fasteners, as they are oval shaped and seem tighter to start with? Any experience with this would be very helpful. Thanks, Mike |

Didn't someone reccomend heating the copper gaskets up with a torch and letting them cool to soften them?
