Fuel in oil kioti dk55

Trent orosz · Dec 15, 2021

I have a kioti 55 that the engine oil is filling with diesel fuel while running
Enough that it blows out the blow by after an hour on a fresh oil change
My thoughts are injection pump leaking but how or where and is this a. Common problem
I have looked on numerous sites and forums but can’t seem to find something similar

Sounds like a bad fuel injector but I could be wrong.

I believe your injection pump has a failed seal and is leaking internally. Unless you are very adept at fixing it, I'd have a dealer do it. Constantly getting diesel in the lube oil will eventually destroy the crankshaft bearings.

It could also be a failed diaphragm on the mechanical fuel lift pump, if so equipped. I would check that first since it is usually pretty easy to get at and replace or switch to an electrical lift pump.

Just a suggestion.
