Bill,
A block heater is a good idea anyhow. A pre-heated engine use less fuel
than a cold engine, and the interior heater will deliver warm air
sooner. :-)

My questions all revolve around cold weather starting.
What is considered cold for a Diesel?
Having used diesel buses for 9 years answer is, it varies on the
engine. I found Internationals and Cat engines would start in -15 or
so with out trouble, Mercedes engines had to be helped along. Older
Internationals needed to be plugeed in around -5 or so.
Should plugging in the block heater make a difference?
Yes plug it in.
Can glow plugs be flakey?
Yes they can be flaky, our rule of thub was to cycle the glow plugs at
least 3-4 times before attempting to start iyt when it got to -5 or so
with out a plug in. Yes Wabasto heaters in the newer Internationals
and Thomas built buses are a god send but they break down a lot. I ran
mine off a timer set 30 min before i arrived at the bus.
Some Webastos have the electronic controller built into the case, above the
combustion chamber. Guess what happens? Yes, "frying tonight". Long term
answer is to remove said controller to a cooler place. Actually it has to be a
new controller, as they are "potted" and effectively unrepairable.
Does knowing that make me a wonk?

If there are any diesel wonks on the forum, your thoughts would be
appreciated.
