Hi all
I have a Kubota D722 that was supplied with water in the cooling system rather than coolant!
The engine sat on its delivery pallet for a year and we had cold weather (-6 deg c) for a month or so.
I believe the engine was only half full of water but it still did some damage. It popped one core plug out and cracked the thermostat housing. As its a cast iron engine, I ran it up to temp today to see if I could see any issues. Apart from the leaking thermostat housing, it ran fine. I drained the oil and it has no coolant in it. I had to pull the head off to replace the thermostat housing and found some marks that concern me.
This engine has 0 hours on it and is new apart from some idling. There are these marks on the front and back of the bore:
This mark is slightly above the core plug that popped out:
The engine runs fine and has good compression. Thoughts on what I should do?
