White smoke on cold start.
Hi all,
I'm getting what seems to be too much white smoke from the exhaust on cold startups. Since 30 deg F means "cold" to some
, I want to clarify the temps I working with.
I get a huge plume of white smoke that pretty much envelopes the truck when it is not pluged in from 10 deg F to -10 deg F (typical daytime highs here in No. MN). Plugged in at these temps I get a decent amount, maybe about 1/3 of the truck enveloping cloud. I get a little of the romp-romp at these times too, but it's not what I would condsider anywhere near severe. The engine always starts with minimal cranking.
I tested the GP system today. Six GP's Ohmed at 0.8, one at 1.5, and one at 0.7, all within or darn close to the 0.8 to 1.5 Ohm tolorences that I have found. GPR output to glow plugs at key on is 11.07 VDC. Does this sound a little too low to you guys?
I've read accounts from many on the board that in cold weather with a proper glow plug system, nearly no white smoke should appear. I don't know if they ment 30 F, or an actual cold temp like 0 or -10F. Is this cloud normal for the temps I am dealing with?
Thanks guys

She'll smoke when it is that cold. As long as it goes away after she reaches normal operating temps.
I see a huge difference in the amount of smoke from 30 degrees compares to 10 degrees outside air temps. Plug her in like barry said - if she cranks right up as you say it sounds like your glow plugs are good. Just keep an eye on the batteries.
Hey Barry - looks like I'm chasing you around FTE tonight!

Ok that's what I needed to hear. I figure a good bit of smoke at those temps would be expected, it just conflicted with what I read about for "cold" starts. I plug 'er in whenever possible, but there are plenty of times that I can't.
zx250, I usually let the glow plugs run 2-3 times, turn key on and let sit for up to 2 min as I shovel snow or scrape the truck off. Definately cuts down on it a bit, but it still makes a heck of a cloud, which goes away when up to temp. Batts are good, 12.9v @ KO.

My truck does the same thing... I never plug it in but then again i never see temps below 30 in the morning when it gets started... But it is ALOT of smoke and it still worries me. But i cant say it effects anything and once my EBPV decides to turn on the smoke stops.
