I recently borrowed my Farmall M to a neighbor who needed it to run a small PTO driven saw mill. He reported that after using it for a couple days, some oil blew out the bottom of the tractor, roughly the part of the tractor frame below the gas tank. I went over to look things over, and noted that the engine oil level is OK as was the gear lube in the rear end. The hydraulic oil was below the dip stick. We added oil to the hydraulic system, and started the tractor. It did not appear to leak anywhere. Yet the neighbor said oil had been expelled quite forcefully, and I could see there was oil on the ground under the tractor, but it was tough to determine just how much.
Anyone have any idea what might have caused the oil to shoot out?
 
The tractor running under pretty good load could have boiled the oil in the Lift all. It would take less than that if someone pulled back the lift lever and it ran dead headed against the pressure relief valve. If there was any water from condensation in the oil (murkey yellowish) it would do it in less than an hour for sure. It probably came out of the fill cap. If that is sealed with a real pipe cap instead of a OEM bakers hat type vented cap, it could have been forced out the pump seal, and run out the inspection cover. Jim
 
Maybe the crankcase breather tube was plugged up with crud and condensation and the workout on the saw was enough to clean it out. Tube comes down behind rear of one frame rail, right side maybe.
