engine problems

[Duckz]

HI i have just purchased a D22 Z30 Nissan Navara, unfortunately it is bubbling water out of the radiator cap when removed, i suspect a cracked head, new to deisels i am unsure. and can i just replace the head or will it require a whole engine rebuild?

The engine is making a high pitched squealing noise also.

Looks like u need someone to have a real good look over it.

Yes u can just replace the head.
But u will want to be pretty sure the rest of the engine is ok before u lay out cash for a head.

These engines can get pretty expensive to repair.
