You don't need to remove the rear exhaust pipe to replace the oil pump. I hope you didn’t do that just to service the pump. Also, rarely do these pumps actually go bad. If replacing to solve a low oil pressure issue at least go to the oversize pup to try to help with that problem. Even with that most likely the problem is something is worn such as the engine case itself or there is stuff clogging the pump inlet screen.

Subject: Oil pump day..

And I already hit a snag..

While removing the rear exhaust pieces, the top left side bolt sheared.
There is about 3mm of bolt sticking out. Enough to get some vice grips on.
I've deep creeped it to death. Before I go about extraction, is there an easier way?

What bolt should I use to replace it?
