Dexta diesel has fuel in crankcase

FarmallM51 · Nov 3, 2020

Found what appeared to be diesel fuel in crankcase oil. Drained crankcase, left plug out, filled fuel tank & left overnight. Fuel dripping from sump drain. Pulled fuel lift pump away from engine block about 1/4" but don't see fuel dripping from it. Where do I look next to see how fuel getting to crankcase? Thanks.

The lift pump is on the injection pump on a Dexta so it is unlikely this is the cause.
The leak will be on the fuel tap/pre heater in the intake manifold. This was a common
problem and, back in the day, Ford had us install a tap at the manifold end to turn the
flow off.

That's it! Thanks. I'll try to find a tap for that size copper today.

Engine won't turn over, so I assume that one or more of the cylinders is full of fuel. What's the best way to aspirate the fuel from the cylinders?

Remove the injectors, then turn by hand to get the worst out, then spin over on the
starter replace the injectors and fire her up. Do not try and use the starter with
bores full of diesel you may bend the connecting rods.
