This morning I was on my way home from work (3rd shift ),and I'll admit I didnt let the truck warm up like I usally do. I passed a big rig(35 in a 55 come on) and i noticed a thin cloud of white smoke cummin out of my tail pipe above 2k in 5th gear. Engine temp was about 150 or 160. The cloud was big enough to get my attention in the rear view mirror. Should I be worried? Oh yeah the outside air temp was about 40

 

Any other problems surface at the same time? Most white smoke can be attributed to either the overflow valve sending the IP to much fuel pressure, also there is the timing which if it slipped enough could allow this to happen.

 

no, everything else seemed fine.

 

was it light outside or dark, cause if its dark, it looks like your truck is smoking alot more than during the day, just from the glare of the lights, but if not then???

 

No it had been light out for about an hour and a half. I m going to try it again this morning when I leave and hope it doesnt do it after I let the truck warm up first
