Seems like lastweek i noticed a puff when she starts cold or hot.....Not much just enough to see........

I was thinkin the Comp box had something to do with this, but i dont know if thats correct....

I keep the box on level 2 x 5 all the time....Never have run higher yet.....

Should i be worried about this?

 

Black smoke correct? No big deal....................Pete

 

Yea i think..........I will double check later.....I assume its just excess fuel?

 

That is normal. Will vary depending on ambient temperature, and how long engine has been sitting.

 

Mine puts out a little puff of grey smoke right at startup. It's just the unburned fuel in the cylinders preceeding the first one that fires. I'd consider it normal.

 

Ok guys thanks.........Yea its a greyish/black smoke so it sounds like its normal....It just didnt seem to do it when i bought the truck a mth ago.....

Oh well thanks.....

 

Temperature does strange things to Diesels.

It's probably a little warmer now then when you bought it

You'll see all kinds of changes as the seasons progress.

Just wait till mid winter when you do the white eye burning smoke fogging the neighbors.
(or filling up the garage if you have one)

Phox, I thought that was your mud flaps melting!!

 

Mine has done that since day one. Even without mods...

 

Yeah, it sounds normal. Just wait till you get some cheaper diesel. I know that mobil diesel seems to smoke more then amaco. It also has a different smell, I think it is because of the different sulfur content.

Thought i was the only one who liked smellin diesel....

 

yeah, us dummy students ( my class) we all decided we wanted ours to smoke during class so when we rebuilt the engines we left a lil excess in the cycliners

yeah it didnt smoke. just shot fuel up into the air through the stack. made a hell of a mess.

 

cool, mine does the same thing since i bought it used about 2 months ago. I never asked cuz I didnt want to hear any bad news! Already have tons of bad news need some good news soon.

 

It all comes out of the same pipeline, no matter what brand name.

 

Yea I also have a little puff of smoke out of my tail pipe =(
