4500 backhoe diesel in oil???

hi,

i have a problem with my new backhoe. after i got it 4 weeks ago i changed engineoil.

now after arround 10 hours of working there was very thin oil coming out of a hole under the clutch. then i found that the engine was full of that thin oil.

is it possible that diesel gets in to the engineoil and that much in that short time???

and what ist the fault? the engine is starting very bad, too.

i found something about other tractors but not ford.

any ideas? thanks

bad rings maybe? that would cause hard starting too.

your fuel pump diaphram is blown. remove the pump, and buy a new one. not worth fixing. then you have to do a very throughout oil change, and filter too.
finally, you have to bleed the entire fuel system, purge air out of all fuel lines, very time consuming.

good luck

thanks for the fast answers!!!

rings? would this cause high preasure and oil coming out of the breather???

fuelpump was my first thought but i found that the old ford doesnt have a pump as the tank sits over the engine????

right?

Does it leak into the crankcase with the engine running? Does it still fill up with the engine shut off? Probably the easiest way the tell this it to drain the oil then put a clean bucket and see if it starts to fill up with engine shut off. It maybe the umbrella seals on the pump shaft or the return line under the rocker cover. I would not run it in it's present condition. I would not just go and buy a new pump $$$$ because that may not be your problem.
I am changing over my computer system so I might not be able to respond for the next couple days.

If it's gravity feed, and there is no fuel pump to the side of the motor, the only other place would be a leaking injector pump. is yours driven by the timing gears/chain cover area? it could be a bad seal.
other than that, you have a dead cylender, you should have done a cylender drop test when it was running, by simply cracking the injector loose a 1/2 turn, and closing it tight again while the engine is running. I know not everyone is confortable doing this, but that may tell you if you have a bad cylender, maybe even a bad head gasket?

Oil coming from the breather concerns me a little. Do you have a paper air filter, or the old Oil filled canister breather?

I doubt it's an engine problem. If the rings were that bad, it wouldn't even start. A dead cylinder on a 3-cylinder engine makes the tractor virtually useless.

Yes possible and fairly comon. Diesel fuel is getting past leaking shaft-seals in the injection pump and sending diesel fuel to the engine crankcase.
