I was watching the video Oil in Coolant and I have just the opposite, Coolant in my oil and no sign's of any oil in coolant. Once I found this was happening I changed my oil and ran my tractor for a few minutes, maybe 10 at the most, and a couple days latter I found once again 75% of my coolant in my oil. My tractor is the L185 17 hp . Can you give me any ideas on what too do and what may be my problem.
