Interesting post & thread about idleing a Diesel.
Trucking industry magazines have carried articles for years about the evils of PROLONGED idleing.
During my time with Caterpillar, I remember that in the truck shop, they would check the computer readout for idleing time, and some warranty claims were not honored for this reason.
During my time with Detroit Diesel, I remember surveys at truck stops to check coolant and oil temp, for "slobbering" and white smoke.
It didn"t matter whose Diesel it was, after 3-4 hours idleing in zero and below weather, the coolant temperature would drop to the point of misfiring cylinders and white smoking.
Oil pressure doesn"t have anything to do with it.
At low idle, cold intake air will chill the cylinder to the point of misfiring, but the engine will continue to run on serveral cylinders, though raggedly.
The "idleing" thing got started in the old days due to poor batteries and difficulties getting a Diesel to start in cold weather.
It was understandable, if the thing wouldn"t run, you couldn"t work.
They have got to be covered up or plugged in.
My 2 cents.
