The only thing I found was a break in the head gasket between 2-4 and 6-8 but not 4-6 so Im guessing this is my problem. what do yall think?
This is one for the record books. I wonder if Guinness has a catagory for strangely blown head gaskets.
I'm thinking that if there was enough coolant in the center cylinders to blow out the gasket material in the outboard cylinders that digging into the bottom end looking for cracks in the pin bosses, bending of the rods, crushing of the rod bearings, etc. is in order.
Off the top of my head with your first post my guess would have been a problem with the compression gauge, like the thing leaking down through the Schrader valve from a small piece of dirt holding it off its seat. This is way different.
