Hi VIC or anyone who can HELP. I have a L185 DT with a z751 motor it has the right oil pres called for in the man. But if you run it mowing with a 4ft field mower,or any exd. period of time it will push oil out the breather. The oil comes out slow but a steady stream. It has done this for along time, the motor was rebuilt and runs and starts great. I have the oil baffel in place and it still runs out. I have to keep a oil bottle on the breather hose to catch the oil. If i run the tractor for 2hrs. it will push out 1/4 of a qt. or more of oil. I have used 10-30 15-40 20-50 it still pushes out oil. Is there too much oil going to the top of the motor? and what can i do to help this problem. THANKS ALL REPLIES WILL HELP. Mayco
