How does diesel fuel get in the crankcase Massey Ferguson 165?

Diesel fuel can enter the crankcase of a Massey Ferguson 165 due to a few potential issues, such as a leaking injector or a malfunctioning fuel pump. If the injector is not sealing properly, fuel can seep past it and mix with the engine oil. Additionally, a failing lift pump can allow fuel to be drawn into the crankcase through the oil return line. Regular maintenance and inspection can help prevent these issues from occurring.
