Execessive Smoke

[BE Snowplowing]

I have a 2000 Silverado with 290,000km on a 5.3L. I live up in the great white north of Canada where currently we are sitting at -20 degrees below zero.

I use the truck as a snow plow truck also.

Can anyone tell if how much exhaust smoke is to much, the reason why I'm asking is I noticed last night that there was lots of exhaust smoke even after the truck had been running for over 3 hours.

The truck is VERY well maintained, does not use any antifreeze, the oil and coolant are clean, the exhaust smoke smells like exhaust, not coolant. So I was just wondering.

Oh ya and it was -22 out last night as well

Thanks
Brian

At -22 plowing snow you are going to get exhaust smoke.
When hot air hits cold air ==exhaust smoke.

looks like down here some of that cold air is going to fall on us.
the exhaust is most likely condensation. the higher the humidity in cold weather the more condensation. starting the engine down here in the morning with high humidity and lots of frost and dew you get much more exhaust smoke/water coming out. at idle this create alot of water.

starting later in the day this usually only for a short time as the air has less humidity in it.

grass still green here. 2nd warmest dec ever.

last year more snow than you could handle. ended up 7 ft total..
