I did the gasket on the side that blew out. Also use a bolt with a little half moon shaped attachment that slips over the bolt and then clipped in place to keep it from rotating ( similar to safety wiring).
I went to change out the other side and I can only get one bolt out. I think George Atlas torqued these down, and Pee Wee Herman did the side that blew. There's no room for a box end and a barely room for a open end that will strip the head. I've tried running the motor for a minute to heat the head and get it before the bolt swells but that didn't work.
If you look at the above photos you will see what I mean.
Other than using a cutting torch, grinder, jack hammer, or similar tool , does anyone have suggestions how to get these little buggers out?
