A while back I was looking for what was causing the oil level in my engine to get higher as I ran it after changing oil. It turned out to be I was over filling the crankcase, the factory sticker on the engine says to fill it with 4.1 quarts however I checked with kubota online it shows 3.6 quarts. I did pull out the original service chart that came with the tractor new , it also reads 3.6 quarts. A lesson learned, do research from several sources before jumping in. Thanks to all the members who gave valuable input.
