What would cause so much smoke to coke from the exhaust like this?

Hes a livestock hauler, he ain't going to just hit the shoulder and call roadside assistance... He probably knows of a place to get safely off the road a short ways up the road where he can fix the problem, which is probably a blown turbo.

 

Truck just doing a regen

 

Lol... That was my first thought too, until I saw the rig.

 

Still gots a def tank of the side of the truck. Who knows if it just for looks tho.

 

True. We have a few trucks that have DEF tanks that are just for looks.

 

Just did a blown turbo on a hoe with all that fancy emissions junk on it, smoked heavy white smoke just like that.

 

I imagine all the emissions junk gets plugged up pretty good from that .. Did you have to replace/clean all of that as well?

 

In addition to turbos I ended up having to replace the whole emissions box since its a sealed unit. Oil was actually blowing out the exhaust and down the side of the machine.

Believe it or not it actually idled pretty good for having a turbo with a detached turbine wheel. It had the twins on it so the larger one was probably still doing its whistle stuff lol.

 

My truck (peterbilt 389) does that once in a while after running thru stop and go traffic. Soot accumulates then it's burned off once you are at highway speed hence the white smoke. A warning that shows high exhaust temperature will appear on the dash. Peterbilt recommended we drive under a heavy load to burn off all the soot. That's the price we pay for having the new Def equipped engines.
