I have a 1996 6x4 Gasoline powered Gator. The engine is a Kawasaki. Recently we started to feel it being underpowered, and lacking the impulsion it once had. Then it started blowing blue smoke. We did a compression check, and that seems fine. Changed the spark plugs. We then checked the motor oil, and smelled gasoline in it. We are changing the oil, but wondering... under what conditions could gasoline actually get into the engine oil? Any ideas? Any help would be greatly appreciated!
