deisel in oil

[andydale]

I have model 3340 Zetor and have found deisel in the oil . Any suggestions on what the problem is?


Thanks,
Andy

Hi Andy, it is most likely the lift pump is leaking into the fuel pump. The fuel pump is lubed by the engine oil . Could also be a really crook injector, or a bad fuel pump, but you would be seeing poor performance if that were the case.
