It's odd that rainwater entered open muffler for 5 or 6 yrs but didn't seep past piston rings into crankcase. My guess is you'll end up having to R&R of pistons/liners. Does hyd oil have water in it due to cracked gear shift boots? If so I suggest to check/clean trans oil suction screen(key 30) when hyd oil is changed. Use only hyd oil that meets or exceeds spec's of J20C.

Hi Tx Jim thanks for reply, ractor has a weather tight Duncan cab no water in there, I don't know how long the muffler been rotted as had can on top when stood up. no discolouration of eng oil, bur when exhaust manifold removed 2 and 3 cylinders exhaust ports full of rusted muffler, so decided to remove head. Any advice would be good as it looks like I need to remove Rad, Oil cooler to get at fan bolts to be able to get at bolts holding water pump to head, is this the best way. Please Help Rocherbob

You're welcome. Removing radiator makes accessing water pump/fan bolts a lot easier. Before removing cyl head I suggest to remove injectors so the tips so you can protect the inj tips.
