It appears that a valve got damaged when water got into the engine (D722) of my 2013 Bobcat 418 mini excavator. I don't know how to pull the engine to replace damaged valve. Any help is greatly appreciated. Also any info on the torque values for the head would be very helpful. Thanks.

bobcat isn't kubota so you won't get a lot of help here

There are a million different D722's out there, might help if you know which one you have

Usually on excavator, you just start taking stuff off/out until you can get to the engine mounts, remove them, and lift the engine out. They are no fun.

If it got water in the engine there's a good chance of a bent rod (or 2 or 3). Valves are rarely damaged by water unless they're rusted/stuck but connecting rods are almost always bent, especially on small diesel engines, such as your version of the D722.
