I found my coolant leak!? What is it?

[Jitneybead]

I think we might be in some competition for worst head damage.

Head off. What do you see?

Pulled the head off my 1990 4.0 Had zero compression on 3 - a stuck exhaust valve. Others had 170+ compression but there was much water in the oil and some oil in the water. Looks to me like there are gasket failures at number 3 and 5, with a ton of gunk in the water ports. I dropped the head off at the rebuilders today - I think i may use a patch for the corrosion on the block, I don’t think its too bad, but what do others see? What do you think? Here is what I found after pulling the head. …

I’ve ultimately decided to source another engine because both my head and block would require extensive repairs to be able to overcome the corrosion damage.

I feel for you, I’m right with you.
