You drivers can get rid of
slobber buildup by running
the heavy equipment trans-
porter under a full load for
1 to 2 hours. That way the
engine will reach normal
operating temperatures and
burn off excess fuel and oil.

D
rivers, you’re asking for trouble when you run the heavy equipment transporter’s
diesel engine for long stretches at low idle.
You’re asking for even
more
trouble if you continually start the engine and shut
it down before it has a chance to warm up.
It’s plain and simple—diesel engines work best at normal operating tempera-
tures. They run smoother and last longer.
Here’s what
happens when
you don’t let
the engine heat
up to normal
operating
temperatures…
• Fuel and oil are not com-
pletely burned in the combus-
tion chambers, leaving carbon
deposits on the engine’s valve
stems. Carbon hinders valve
operation, resulting in burned
valves and bent push rods.
• Condensation
and
unburned fuel—known
as blowby—slip past
the pistons and into the
crankcase. That blowby
in the crankcase mixes
with oil to make acid
and sludge.
• Engine oil breaks down. Poor
lubrication burns up bearings.
• Sludge blocks
lube passages.
Oil can’t get
through to do
its job, so heat
and friction tear
up your engine.

blech!
that’s
nasty!
if your engine is
slobbering, you’re
not operating
it right.
geez!

all this slobber!
what have you
been feeding
this guy?
