Hi guys, I’m pretty new here. I have a 2015 argo frontier with the Koehler command pro 750 efi. Seems like im getting gas into my engine oil from somewhere. Would this be from the rocker fuel pump? Any help would be great

Probably the fuel pump. According to kohler the 750 efi has no carb. It may be leaking past the injectors also. Maybe the computor is loading the engine with excess fuel if that is possible. Does the engine run good otherwise? I have heard of vacum pumps leaking gas into the crankcase, never had one do that to me. Also not to familiar with EFI systems. I believe but not sure but the system has a primary pump and a high pressure pump which are both operated by a onboard computer module. I think.

Fuel in oil
there?s no carb on the efi motors, however, these command pros have 2 pumps.. a mechanical rocker style pump that then feeds the electric one. I spoke with a guy at Argo adventure in South Dakota and he said these rocker pumps have a diaphragm that sometimes tend to dry out and can crack, specially if the unit is not used often. I pumped my oil out and put new stuff in and it runs great, until it?s diluted and overfilled with gas. I ordered a mechanical pump replacement for it.. I?ll let you guys know if it cures the problem.
