Kubota V1902 there is diesel getting into the engine oil. I had the injectors rebuilt last year, about 150 hours on the rebuild. This engine was rebuilt and set for 12 years in a heated shop. I don't know if the injector pump was rebuilt at that time. Where could I check to see if the fuel is getting into the oil around/or through the injector pump. Could it be getting through the injectors? Thanks for any help BJ
