129 with Exhaust Issue
PO attached the exhaust manifold to the block with a single small spot weld so I assume the threads are damaged or worn. I really don’t want to have to get a new block and rebuild but the exhaust leaks allot but it runs great. I am not in a rush but can you Heli-Coil exhaust threads? When the time is right I will cut the weld and get a good look. Anyone have a like issue? Just looking for ideas. Rick
