In my garage I have a security camera. Without realizing that the Kohler was in perfect view of the camera, I was able to extract a few seconds showing the purging of the water from the hydrolocked cylinders as well as a scare when the Kohler tried to automatically start for unknown reasons while my friend and I were looking over the motor shortly after purging the fluid from the cylinders. Sorry, no sound, only video.


Video showing Purging water in hydrolocked cylinders after removing fuel injectors. The fluid came out of each cylinder in great force and looked like vapor. The crud stuck to the ceiling on my garage:

Video showing the Kohler automatically starting for reasons unknown after purging water in hydrolocked cylinders. Keep your eye on the genset's fan blades and when it tries starting you will notice when the blades turn. This happened several times during this short video:

Welcome to the Kohler club, Johnny! I have... Eight? Or nine? Something like that. But my *newest* is 1965, IIRC, and I have yet to obtain any small diesels, so I can't offer much help beyond moral support.

Johnny, it is not dark on that side just not green, Your little yanmar looks like it was run hard and put up wet what a mess but I know that in a very short time it will be torn down and rebuilt to your exacting standards,

Working on hundreds of engines over the years I have never seen anything as gunked up as that. Take it outside and go at it with the hose. Good luck with cleaning the radiator and the depths of the block! As the top end was totally clean that tells me it also was crudded. And perhaps the internals are still filthy. I'd pull the pan to be sure.

That is the plan for today. Luckily I left the Kohler on my trailer, so I will hookup and tow it outside, cover all holes leading down into the crank case such as the push rod holes and cover the fuel injection pump, then blast out the coolant passages in to block. I'm not going as far as removing the freeze out plugs since I think it may not be needed. Water and compressed air should be good enough.

At this moment I am starting the day off with my customary 1 pot of coffee (yes an entire pot), then I have a few house chores to do, then it's off to my playground to play with the Kohler. Updates will follow later today.

That almost looks like one of the frost plugs that rotted out of the block of my Kubota B6000. Also behind the water pump (hmmm....?) If the oil was that clean wonder if it was flushed and refilled without doing the cooling system as well. Excellent job on diagnostic step by step

1tech, not to thread morph, but I also have a B6000 as a daily driver. I did the camshaft plug thing and generally went through the engine for a freshen up this year. Can't get the injectors out though. Any ideas?

Understand, I like oldstuff. I'll PM you the links that helped me if I can find them again. I ended up wire brushing the injector bases and soaking the threads in ReleaseAll for about a week and a half.
