South_Ms, yes the injection pump requires
additional additive to lube the front lip seal on
the injection pump drive shaft. If this seal fails
Diesel fuel will leak into the crankcase.
GM ATF is good at cleaning up the fuel system,
Someone on this post recommend a good commercial
Diesel fuel conditioners. My brother has 454 and
495 with D-179s and he just adds a couple of
tablespoons of crankcase oil every time he add
Diesel to the tractor.

Ask the previous owner if the injection pump was
ever removed and re-installed? The injection pump
could be out of time. When engine is warmed up a
properly timed D-179 will start in less of a rev
of the engine. If it kicks back on starter it is
timed to fast and if it requires many rev of
engine to start could be timed to slow.

Also the fuel tanks on those tractors are famous
for getting junk in the bottom and restricting
fuel flow. Only solution is to take the outlet out
of both sides of the tank, drain tank and clean
out fuel lines.
