S175 Hydralocked- anyone experience before?

[esimp]

One of my employees used the high pressure 4" water hose to clean the S175 today. When he tried to start it, he said it turned over and stopped. Now it clicks. I've pulled the intake, injectors and valve cover so far. It was definitely full of water. I put a bar on the crank and it won't turn at all. Number 2 and 3 cylinders are up, 1 and 4 down. Acts like there may be a bent valve and some piston contact. Anyone else ever had to deal with this? With the Kubota engine what typically is the result? Valves, pushrods, crank? Any help is appreciated. The machine only hsa 500 hours on it.

Valves should be fine, sounds like you may have bent a con rod.
Did it fire at all? If so, you probably do have a bent con rod, you're lucky it didn't pop a hole out of the block. You really need to pull the engine and take the head and sump off to check. You won't need to remove the timing cover as the crank doesn't need to come out unless damaged.
There is no easy to check short of doing that. Even just taking the head off you may be able to see of one piston is sittilg lower than the other, but if its locked up, you need to pull them all and check the con rods.
Good luck, hopefully you will get out of it without spending too much on it.

Maybe pull all the glow plugs and see what comes out of the cylinders.
How is the engine oil. Is it over filled now (water got in?)
Also remove the drive belt to be sure its not a pump problem (not likely, but easy to do)
