• Step 1: Are you tilting the engine or using it at more than a 15 degree angle? Tilting your mower or equipment can cause leaks. Right the machine before moving forward.
• Step 2: Checking and changing the oil is an easy troubleshooting technique for this problem. Check to see if the oil is overflowing or you’re using the wrong grade/type.
• Step 3: Check the crankcase for leaks.
• Step 4: Is the head gasket blown?
• Step 5: Are the rings and/or cylinder worn?
