05 cold start puff of white smoke and rough idle

[brianjbeach85]

I'm probably just siding on caution here, but this morning (temp 40) i didnt plug the truck in... turned key on glow plugs fired for extended time which is to be expected. turned it over fired up after 3-5 sec.. not a long hard start at all. I noticed a puff of white smoke that came out tail pipe.. truck had a rough idle which is too be expected due to temp. after initial puff of white smoke nothing further... i let it warm up and drove away after 5-10mins of idle. Anything i should be concerned with?

Currently 106.5k on the clock. Had cooling system flushed with ford gold @ 105k
Have not deleted EGR yet.. EOT and ECT are within 10deg of each other.. i have a oil bypass and coolant filter as well...

oh yeah and go !!

When you had a coolent flush at 105k and going back with the Ford Gold cxxp coolent that was a wast of $$$$. Do some reading her on ELC coolents and you will get it out ASAP.

unfortunately i didn't do any research on the coolant issue. Knowing this now.. ELC is nothing more than extended life coolant? correct? I only ask, because i know prestone and all the brands sold at like napa or autozone sell gallons of it.

Any issues with this coolant? or should i buy a different type and if so what's the reasoning behind it?

keep up with your coolant filters. Change and flush to an ELC. Fleetrite is what International uses in their engines. As for the smoke question, its normal if it clears up. If it keeps smoking you may have cooler issues,( egr, oil cooler)

Below freezing temps, I have some white smoke that I attribute to condensation build up in the exhaust overnight (or the weekend). It takes half the time to burn off as it does for all the gassers around me when they start up.

The right coolent should say CAT EC-1 Rated, I would check with Cat, Cummins, International there are a lot out there i went with the Delo good for 750k if you check at 300k should due me i only have 123k on my 97 time will run out before the miles

Heres a thread that somewhat has to do with the rough idle on first startup --->6.0 oil analysis on Rotella T-5 10w-30. You will probably like this.

I have the one with info on the coolant in my backpocket somewhere....

Heres the thread with great info about the coolant. It is a very long read but well worth it, post #198 is a good one.

--------> Replaced oil cooler still difference in temps

the white smoke is most likely unburned fuel, unburned fuel is white. I haven't a diesel engine yet that doesn't blow a puff of white smoke on a cold start. nothing to worry about.
