Oh, one more thought. Do you have a fuel filter with a water separator?
If not, definitely install one, and if so, check the water catcher
on the bottom to make sure you don't water in your fuel (should be a
regular check before starting the engine). Water can be drained off
and desposed of as hazardous waste.

Thx Scott I just got some thicker fuel hose with 3/8 ID and some clamps. I
just filled the 15 gallon tank a couple of days before this problem and am
wondering how that might cause the breather hose to fail. Coincidence?
I really appreciate your assistance, at least I feel I'm not alone

There should be some foam or something under where the breather attaches
to
the engine (see the service manual for the engine) that catches oil so
it doesn't go out the breather, but the crankcase gases will still have
cylinder blow-by (partially burnt diesel). White smoke is generally
associated with partially burnt diesel, not oil (that's described as
"blue"),
so that doesn't sound exactly like oil from the breather getting burnt,
or pressure forcing more oil into the cylinders. And yeah, that should
be unkinked. Don't be shy about putting heavier, thicker hose on there
with the same inner diameter.
Running for a period of time at dock making smoke should be okay and if
it's a temporary build-up of fuel in the exhaust manifold, it should
clear.
Too much too long and you're causing soot build-up.
I have some diesel work to do too =|
