How long should it smoke for?

[schlutzer]

I've searched and don't get much of an answer on this. When I start the truck on a -25C or so day (plugging it in isn't usually an option). I get some whiteish smoke.

Now this isn't the bad glow plugs smoke, I get a real small puff of that on the first fire. Then it's all clear for a minute or so. Then I start getting a mostly white kinda blue smoke that last about ten minutes of driving. I see other videos of trucks doing this. Seems to be fairly normal, just seems to be a fair bit from mine 5" straight pipe. And I can't find a mention of how long it should take to clear.


For the record. The glow plug system is perfect, plugs are new, relay is the stancor unit, and fresh UVCH. The truck starts and runs perfectly fine. No loss of power.

Any chance you could put up a video so we could see how much smoke?
Heck -25 and your not pluggin it in and she's starting Id be happy. Im gonna go out on a limb and say your fine. Thats cold. I pray your running t6 right?
How long are you warming it up? Do you have a monitor? How warm is it when you usally take off?

Now I might get a puff out of mine but I've not had any smoke whatsoever after start up. I hear of a few guys having this problem. I would say just keep an eye on the oil level. If its not excessive and there's no power loss chalk it up to wear and tear. (I've only got 95k on my 2002) extra lube for the cylinders? 2 stroke? Lol

I keep going back to the -25 without being plugged in part!

When it's this cold I let it run for about 5-10 minutes, time it takes to clear the snow and ice off it. But like the cold start sticky I keep the Rpms around 1500 and just kinda crawl until the temp gauge comes up into the normal range. Then I still keep it out of boost till she's right warm. Some of it I know will be normal condensation in the exhaust that all vehicles get.

I'm too cheap for the rotella t6. We get boned for prices in Canada, I don't feel like a 170$ plus 25$ filter to do an oil change. So I'm running rotella 10w30 Dino, half the price. Still great for cold starts.

I can probably get a video this afternoon or tomorrow morning after work. Both times it's going to get about a 12hr cold soak and no block heater start. It'll be a hold my phone to the passenger side mirror but should work. Thanks for the reply.

Hey my ford manual says "In good working order, your powerstroke will start unaided down to -35C" or something to that effect. When I can plug it in I definitely do. But I redid the glow plug system because I knew at work there's no option.

My weak batteries scream at me when it's this out. And you should hear the PS pump when it's this cold.

That's a video of a -18C cold start, mostly to be a smart *** to a friend of mine. Taken a month or so ago, I never did get the exhaust in the video
