Have 4cyl diesal with Roos Master inj. pump.
crankcase is contaminated with fuel.
fuel returns seem to be operating properly.
using a later model pump, original pump has
small valve(?} in return line to tank that is not
on newer pump.

Engine runs well Any ideas or comments would
be appreciated

Thank You

THERE IS A SEAL AROUND THE SHAFT THAT DRIVE THE PUMP,TO KEEP THE FUEL SEPARATED FROM THE OIL AND THIS SEAL IS PROBABLY LEAKING.

Al The most common cause of fuel in the oil on these diesels is the return line that connects to the top of the injectors, it is located under the valve cover, they crack from vibration, it is such a common problem that I replace them anytime I do any fuel system work or have the valve cover off, for work.
