Yanmar Problem
 

I have a Kohler genset with a Yanmar 3G (H?)M. The problem we are seeing is
diesel fuel in the oil. It has less than 100 hours.
The fuel pump is electric. The engine starts and runs fine

I have been told of 3 possibles.
-Injector pump being loose on the engine
-Injectors putting in too much fuel
-Umbrella seal on the injector pump.

I am not presently near my boat

It is kind of hard to figure out when/if you have fixed it. You have to
change the oil run it and then do an analysis on the oil.

Any shared experience with this will be appreciated.

It's most likely an injection issue of some sort. I have the 20 KW
unit and Kohler has an excellent parts and labor warranty on those
generators. I'd find your local dealer and give them a call.
