Roger46 said: (quoted from post at 17:38:49 07/21/09) I would like to know why I have never had that problem with my Super H when I have used multigrade oil in my air cleaner for 30 years. I also use it in all my other tractors with oil bath air cleaners and have never seen that happen. The only time I get oil coming back is when I stop the tractor and it diesels and runs backwards. I also dispute that there is any reverse air flow when the tractor is running even at low speed. Sure the flow is somewhat pulsing, but not reversing. Roger
When the engine is at idle there should be about 17 inches water column vacuum on the manifold side of the intake valve and probably a couple PSI pressure left in the cylinder. Since the piston has not started down when the intake valve starts to open, which way is the air going to flow?
In the early 1980's I worked on some trucks that were converted to propane. Before they figured out to limit the total spark advance we had a lot of problems with detonation breaking the center electrode out of a spark plug. When that happened you would find one spark plug missing the center electrode and almost always there would be four damaged pistons, two on each side. This "pulsing" was great enough to move that piece of electrode through the intake manifold to all the cylinders that ran off of that plane on the manifold.
