Re: 4.0 main bearing bolt size question
I really hope it wasn't just your valve cover leaking down the back
imitating a bad seal. You can tell by running a clean rag across the
back of the head. If it comes out wet with oil....
My main's use a 13/16 wrench. It has a 'slight' amount of play when
fitted.

The seal is fitted 'under' the rear main bearing cap in 2 halves....
