I went in to adjust the smoke screw yesterday (to shut a moron up about my lack of smoke...long story) and made my adjustment. Went to put lock nut back on, half a spin and realized it was stripped out. I flipped it and got it tight enough to hold for now. But where can I find one? Is it a generic size or do I need to go Dodge/Cummins house for it? thanks

 

It is a standard metric nut. I don't know the size off hand, though.

 

What's wrong with a lack of smoke?
That means you have a clean running, properly set up engine. ;-)
Anything more than a light haze is a waste IMHO.

 

Smoking makes you cool, haven't you heard? C'mon, everybody's doing it

Just joking around, of course

Running the smoke screw in will give a nice bit of pep before the turbo spools on a stock truck

 

I know exactly what you mean. I just couldnt convince this kid, so Im gonna turn it up for a couple days and blow a nice thick cloud right into his window. Then turn in back down when I put my nut back on.
