Outer main bolt hole stripped (thrust bearing)
Anyay is a helicoil the only option here? I don't like the idea of it, but returning this whole motor isn't an option as the seller has stopped responding to my phone calls.
Thanks all
They make kits from GM to repair these bolt holes. Don't be the least bit worried about them. They will do a fine job for you if installed correctly. In fact, many high end blocks and heads come with Helicoils in them brand new.
