Well I got started in the M now. Ugh this one has been more of a pain. Popped the head to do a gasket I'll have a few days of cleaning that head up but the worst thing to happen was a head bolt snapped inside the block. I spent two days trying to work it out with a punch than a drill and ez out which broke. I hate ez outs by the way than 2 hours with a Dremel to grind the ez out out of the bolt before I could drill again. Stepped it through 5 but sizes but got it drilled out and re tapped. I might still use a heli coil I have not decided if they are tight enough.

Do yourself a favor and invest in a couple of 3/16 or 1/4 inch carbide drill bits. Those will drill right through a broken ez out.
