sorry; i thought we were talking about a situation you were encountering
from a start after an idle.
perhaps i should have said "what do your operating temps fall to at
an idle?"
cheers!

I live in a very hilly area of New York. I never have a problem getting up
to proper operating temp. I am running NA gears in a turbo car as well so
it runs quite a bit higher rpm's than a normal turbo car at the same
speed. That helps keep it cleaned out some.
I also live by Dr.Booth's drive it like you stole it motto to keep it
free of carbon.
Either way a good hill will push it from 90 up to 110 and hold there
steady.

what are your regular operating temps when running WVO?
lots of people in the BioFleet here running WVO, and many of them have
found that the waste heat from burning WVO simply isn't enough to keep the
engine and coolant up to what would be considered normal operating temps
unless running at load down the hwy, and many have gone to warmer
thermostats in an effort to try to keep the temps up closer to where they
belong around town so they don't load the engine up with unburnt WVO.
(that's what contaminates oil and ends up being the death of the majority
of the former WVO candidates that are crowding the salvage yards around
here to the point that you can't give them a 617 unless you also tow it to
their doorstep.)

Grant,
I think you may have nailed it. It only happens on extended idle,
usually in colder weather and more often with higher wvo concentrations.
It never puffs smoke on startup(valve seals do that) and only on occasion.
Thanks, Mike

"sit and idle" are the operative words here I think.. A diesel engine at
idle will stack unburned/poorly burned fuel in the cylinders and exhaust
when idled for any period of time.
This is due to the lower combustion rate in the unloaded engine and
slight
overfuel condition to sustain idle [so I'm told].... which is why the new
rules for parking semi tractors went into effect. When they start pulling
after idle they smoked and rolled coal.
Could be you have one or more fuel nozzles that are not still making a
good
spray pattern, which gives large droplets of fuel which take more heat
and
energy to light off, available at higher speeds and greater loads on the
engine.
Just a few thoughts,
Grant...

After letting my 300d sit and idle it sometimes blows a quite large
cloud
of oil smoke out the exhaust as soon as I stomp it to the floor and go
down
the road. I am guessing at bad turbo seals. What else could I look
for?
I am wondering if there is a different turbo I can run for a bit more
boost if I have to replace it. I recently sold my hot rod Beetle so now
my
son and I have decided the Benz should be our next "rice eater". Lol
Thanks, Mike
