I have a John Deere 400 with 60" deck. I had to take it to a temporary job at our church 3 acre site while the church mower is being fixed in a shop. There are lots of ditches, ruts, culverts, etc that I mow through. When my tractor tilts going up or down a ditch, or is sideways on a slope during a turnout, I get oil smoking until the quantity that got in the cylinders on the slope burns out, especially if the oil level is full or slightly over. The question I have is how the oil is getting from the crankcase/pan area into the combustion chamber? What is the path being followed when I'm on a slope surface?
