All right guys and gals, belly up to the bar. We have a 30 with the flat head that has us sweetlandites (Sweetland Township) scratching our heads. The engine fires right up and runs smooth, however after running a little while a fine stream of motor oil begins flowing from the breather pipe on the side of the engine. the more rpm's the more oil runs out. We are assuming crankcase pressure is the problem. Compression tests are from 108 to 124.
Now, when you put your hand over the breather pipe you can feel light pressure but not great pressure. If you remove the filler cap used to put oil in the stream of oil stops. So, we are back to crankcase pressure buildup not allowing the oil that is flowing down from the head to enter the crankcase through the 2 slots at the bottom. Is there another slot or hole in the head to equalize the pressure that may be plugged, that I don't see? Perhaps the wrong head gasket? I purchased this Tractor a while back, and it has done this since then. I am not sure if someone non-Massey had it before us and created a Monster, or what. Any leads would be greatly appreciated !!!!! See you all at Massey Days !!!!!!!!!!!! Tim Pace
