Unidentified Engine problem, advice needed.

Wouldn't that kind of depend on if the fluid was in one cylinder or both and/or on the position of the piston in the flooded cylinder?

 

Kinda yes, but for it to lock in both directions this would need at least two cyls to be full of water, AND both valves on both cyls to all be closed at once. Vanishingly unlikely.

I would try removing the injectors and see if she would move with them out, that way you will have a better idea of what's going on.

I can come up to Napton this coming week, pm me your details and we can arrange a meet.

I had a look at this engine yesterday and it is indeed locked up.

The cam box was loose where the previous guy had looked at it. When I removed it, I noticed that the cam chain tunnel appeared to be full of oil.

I removed the dipstick and oil poured out, probably about a gallon!

I then pumped the sump dry, getting out a further 2 gallons but no water.

The oil was very thin and smelling of diesel. I suspect that the fuel pump has been leaking fuel into the sump, filled the cam box and when it has been left standing, has leaked past the valve guides on any open valves and filled the combustion chambers which has locked it up as soon as it has attempted to start.

I didn't have sufficient tools with me to remove the injectors but will return to continue my investigations.

Watch this space!

Justin at the Bottom Lock.

 

If he cannot work it out, ask Jonathon Hewitt at Union Canal Carriers. That's who everyone goes to when they cannot resolve an engine problem

I didn't know if he traveled. Looks like Captain Fizz is on the case. I don't know him yet but will keep a look out as we are in the area for a week.

[Captain Fizz]

I cannot get back until next week but will let you know what I find.

No doubt about it David, Jonathon certainly knows his stuff. He helped us out this week with the fuel pump timing on a misbehaving Petter.

So, I popped over and took out the heater plugs. we turned the engine over and sprayed fuel everywhere from one cylinder. I put the heater plugs back and it started

 

Next question is, how did the fuel get in there?

Only thing I thought of was fuel gravity feeding from the spill rail if that is possible, I really don't have a scoobie.

I've got the injectors for testing in case one stuck open. It could be the lift pump if it has that kind of pump, or a seal in the main pump

 

I'm now trying to find a manual for the Beta B3KC1, or it's Isuzu equivalent

OK, not the lift pump then, it hasn't got one

Engine is now fully functional again thanks to Richard. Hurrah!

[Captain Fizz]

Well done Richard, what was the problem in the end?

As you spotted, an engine entirely full of diesel is going to,hydraulic lock. As a first step I took out the heater plugs, span the engine over, put the plugs back and it started.

 

Next, injectors out and sent off for reconditioning. On test, they were hosing badly - delivering fuel below the cracking pressure. These were so poor that they would leak under the pressure head from the tank, filling the cylinder and via the gap in the rings, the rest of the engine

 

So, we fixed it
