My Kubota L175 with Z750 engine [1100 operating hours] spits oil droplets through the exhaust system. The engine oil level increases 1/4 quart between changes but is not coolant. Have had the injectors overhauled which did not stop the problem. The shop that overhauled the injectors suggested overhauling the fuel pump. Is this the proper sequence procedure in identifying the problem or does kubota maintenance experience suggest another problem or direction in repairing this problem?
The injectors never cause fuel in the oil. It is always the injection pump.
The injection pump plungers wear and the fuel then enters the crankcase .
The oil out the exhaust is from oil being to thin. Or the vent on the rocker cover needs a good cleaning.
Do not run the engine with the thinned oil, or you will damage the bearings and the pistons.
The proper sequence was to have done the injection pump first!
Let me know. Thank you.
