So I picked up a 62 super major that is in really good shape. Blew some white smoke and I beleived to be a headgasket issue. After pulling everything apart turned out one of of the head bolts was stripped. Started thinking about options and rather then oversize it thought I would try the Helicoil route.
Took the bolt to the local dealer, and picked up the right kit supposedly 1/2" #20). Drilled the hole 33/64 and inserted the corresponding tap. Went to insert the helicoil and it was a little harder to turn in then expected. Put the bolt in and it mashed the threads and pulled the helicoil out I also think it messed up my original drill and tap job. Did I do something wrong? I haven't ever put in a helicoil before.
So what do I do now? Oversize it or try another helicoil? Anyone had a similar issue.?
Thanks,
