Remove front shaft for front end(thanks skipmarcy for the help) removed oil pan and rod caps. Bearings were in excellent condition for connecting rods.last night 9/21 after work, removed intake & exhaust manifolds and valve cover. Today I removed cylinder head and found part of the problem. Exhaust valve seat on #2 cylinder had come loose and destroted itself between the head and piston. Going to take head to machine shop to see if it's cracked and can be repaired but will need another piston. Hoping head can be repaired because they are quite expensive. Still trying to get camera to take pic's.
Since you had a mechanical interference between the piston & head you need to have that rod checked very carefully for straightness, especially important in a diesel engine. If it were mine I think I would go ahead and replace the piston & rod as an assembly instead of just a piston. Just a slight kink in a rod on a diesel throws the compression off not to mention it being a weak link too. Good luck with the head, maybe it can be repaired without great cost. My engine has been a good one, just clicked over 2255 hours today and doesn't use a single drop of oil between changes. I do have a fuel leak starting around the throttle shaft in the injector pump but so far not serious.
