Buy the factory shop manual
Note these engines appear to spin a bearing I think on the vibration damper countershaft and blow through the side of the engine. If you hear any different noise out of the engine, shut it down and take it apart. Mine started at about 2000 Hours

Probably a blown head gasket. Coolant will not compress. but will burn off. If the leak got too big and was leaking onto the piston... You probably just broke it or the rings or the connecting rod. Engine job...!!
You should get it to a dealer or a good diesel facility asap, it sounds like a blown head gasket-driving it like that will damage crank and cam bearings or worse, so it is not worth taking a chance-these are prone to blown head gaskets btw.
yes, air intake, intake manifold and exhaust manifold. This is not a job for a novice. If engine has overhead cam, then cam chain/belt must also be removed. Rocker arms must be loosened to allow valves to close. Note position of timing gear in case cam rotates while chain/belt is off. Camshaft must be properly timed to the crankshaft on reassembly.
Head should be checked for warping and cracks. Follow torque instructions carefully when reinstalling the head.
This is only a guess but would say above 350psi at operating temp with a max difference of 70psi between cylinders.This is the spec for the John deere 455 diesel mower and could be or not close to what you need.Hope this helps.
are you sure the cylinder head gasket has blown and not the rocker cover gasket this is at the top of the engine its rubber if it has it takes just a few 10mm bolts to undo then replace the gasket and no need to time up'.if you have the head gasket blown very rare you should buy a workdhop manual
