Re: 1987 Olds Pro-touring project build *LONG*
Well, I was hoping that I could put a longer bolt in and solve the problem but it was a no go. I checked the bolt length and it had plenty of engagement.
When I unscrewed the bolt, this is what was still on the threads of the bolt:
At first I thought it was a heilcoil but it's too rough and jagged to be one of those. It actually looks like the aluminum just sheared off perfectly from the outside of the threads.
Just need to pull the intake (again!) and fix all of the bolt holes with helicoils.
