Broken exhaust stud
As I rebuilt my cylinder head over the winter, I was in need of an exhaust stud.
Rather than wait for an official replacement, I used something from my local fastener outlet that, I was warned, might be too brittle for my application.
Driving at night, I hit a big pothole and that stud broke. There isnít enough of the stud left to grab. Iíll have to get creative. The exhaust still seems to seal fine below about 2k RPM, but above that it sounds awful.
Seems I have no choice but to pull of the cylinder head again to properly extract the stud. F**K!
Before I do, Iím hoping against hope that someone here can provide me with a suitable bodge. Is there some product that would provide a suitable seal where there is no stud?
JB high heat putty, maybe?
