There are only 3 places fuel can enter the engine when its not supposed to be there..
1> the injectors.. if the injectors are stuck OPEN they will dump abunch of fuel into the cylinders.. BUT, you'll get a tremendous amount of BLACK smoke when that happens..
2> a supply pump.. if your machine has a mechanical supply pump attached to the engine block.. The diaphragm can rupture & dump a massive amount of fuel into the crankcase.{oil}
3> the injection pump.. I see on your machine u have the PFR style Zexel pump? Small pump that sits into a slot on the engine & has 4 hold down screws on the corners..
If its the injection pump, the pumping plungers get worn & allow fuel to pass between them & into the oil..
But if that happens, the machine will be very hard to start, due to the worn plungers..
