Changing my timing belt and found that the mount bolt on the tensioner seems to be stripped, don't want to tap to a larger size because the diameter of bolt just fits the tensioner. I was thinking of maybe using a insert or helicoil. What do you folk's suggest? Any opinions would be greatly appreciated.

Thanks!

 

the bolts hole
is that not part of the oil pump casting?
if the surrounding metal is sound/solid yes i see no problem using a helicoil to repair it
or a thread repair epoxy (permatex) works well used on an outboard motor coil mounting bolt hole
