the other day it was REALLY COLD (-13 with windchill) and i was late for work in the morning.

typically, i let the engine idle for a while and just sit in park letting it warm up and giving the oil time to circulate (at the absolute minimum 30 seconds, max 5 mins), and ive been really good about it.

however, this one morning, since i was running late i just turned it on, shifted into drive and went. :pat: the truck sort of coughed (but not really.. hard to explain) and i noticed i was emitting fumes from the tailpipe like i was burning oil (seen this on older pos's).

i drove two blocks with it still happening, then it stopped... and has never happened again.

is this because i just started and went and it was cold, or should i be concerned?? What did this??

Lee-

I would guess it was just running rich as the ECU should be sending the engine more fuel for a cold start...so there was probably just some unburned fuel coming out with the exhaust. I would only worry about it if it becomes a persisitant problem. If you have ever owend older carb'ed vehicles, it wold be similar to the choke staying closed while you try to excellerate and the engine not getting enough air in the mix.

I agree with Jayson. Sounds like it didnt like you rompin on it cold.

Yep, you always need to let it warm up at least some when it's cold.

-13 windchill is nuthin. Metal doesn't care about the wind. It was -31 F (-45 wc) this morning here. I have to admit, it was kinda chilly.

I you sure it wasn't just water vapor? If you notice when it is very cold all cars will emit a lot of water vapor or steam into the air untill they warm up. You probably never notice it because the vehicle is warm when you take off.

lee

no, it wasnt vapor, it was blue smoke..

hey, the car has been running great since, though ive decided (after much -ing to myself) that id rather be late!

thanks for the calming words of wisdom.

Maybe since it was so cold the metal had shrunk enough that some oil was able to pass by the rings untill the motor heated and expanded.

Blue smoke is usually burning oil.
Black smoke is unburned fuel.
White smoke is antifreeze.
Grey smoke is your tires.
Blue smoke on start up could be valve seals, valve guides,piston rings. Keep your eye on it. Might just be a fluke thing.

Feels like summer here and I'm still scared of rain, still got a dirty truck

I did on Saturday. I dried off everything and my doors were still frozen! Then to top it off, it snowed 5inches on Sunday, so my vehicles are dirty again! :pat:

lee

i wash my truck at minimum every weekend, at most every 3 to 4 days.

i hate salt. i especially hate salt on my paint reaching all the way up to my windows.

Phil

In the winter, I use a stick of white grease on the seals and keep the locks lubed. I rarely have problems.

In the winter I usually get a tan while washing my car.
