powerstroke smoking/hazing at idle

I have a 2000 F350 7.3L with the mods in my sig. I noticed about 1500 miles ago the truck hazing/smoking (whitish color)at idle cold or warm. All my gauges are reading properly. No fuel leaks. Truck runs properly and sounds good. Truck looks like a hoopty at stop signs and signals when it is smoking/hazing.

Have you ran a Contribution test on the injectors? White smoke commonly indicates unburnt fuel most likely left over in the cylinder after shut down. Even when the truck warms up to operating temps you say it still does it?

Re: powerstroke smoking/hazing at idle

yea even when it is warmed up! Injectors have about 2500 miles on them. They were replaced 2 months ago.

Re: powerstroke smoking/hazing at idle

Who replaced them and what were they replaced with? could be another bad inj or maybe a oring got cut during the install. I would listen to jody/diane and hook it up to a AE or some type of scan tool.

good luck, mines doing the same thing but im 99% sure its low compression or a bad injector and plan to find out soon.

Re: powerstroke smoking/hazing at idle

me and a buddy put them in and he has done them before, he knew all the little tricks. I got the injectors from full force diesel, they have a warranty.

Re: powerstroke smoking/hazing at idle

Does the exhaust smell like kerosene or nasty burning oil when it is hazing?

Re: powerstroke smoking/hazing at idle

Well, the little trick we techs use is:
you did something to it, and now it does "X"
so go back to what you did and start there.

In this case, I think you're looking at pulling/visually inspecting the injectors & O-rings.

Don't just sit back & speculate, pull them and check.
