There is a exhaust leak on the heat riser. I replaced the gasket but that did not work. I think it did not work because the stud on the exhaust manifold side had snapped. So i drilled it out and taped it but when i reassembled it the threads broke so i could not get enough tension on the gasket hence the leak. Any suggestions? (my thought it to drill the hole over and retap it then use some permatex high temp gasket maker.)
