I snapped off a RH exhaust manifold stud during my fifth attempt in 30 days to seal an exhaust leak at the RH Y-pipe/manifold connection of my 1990 RR Classic.
I've had a chronic leak at this location over the last 6 years. I've blown out 3 gaskets on that side, and the nuts are constantly coming loose. I've made numerous attempts to adjust the system to relieve excess pressure on the joint, and I've tried many types of lock washers on the studs. In this last round of repair, I could not get a seal. I noticed that the stud I snapped off was slightly misaligned. I didn't find cracks on either the Y-pipe or manifold joint faces. I did find minor damage to the RH engine mount -- it's buckling about a 1/4".
I need advice on what to do next: I'm afraid that I'll go through a lot of work to replace the studs and the system will still leak.
