I have a 97 powerstroke with 166,000 miles. It has stage 1 injectors, a modded 17 hpop, and a dp tuner chip. I was recently on my way home and truck made a loud clunk and started blowing white smoke everywhere. It is running very rough and doesnt want to stay running. I pulled injector plug 1 at a time and all it did was make smoke more black. I was told maybe an injector. Any info would be greatly appreciated.

 

Best I can do for you is suggest that you check out the 7.3 PSD forum specific to your engine/drivetrain. You'll find it HERE. I've already request that the MODs move this thread over there so you can get better, more specific, help.

 

Moved to the 1994.5 - 1997 7.3L Power Stroke Diesel forum.

 

First thing I'd do is pull the valve covers and see if I could see anything wrong.

 

Yup, like Darin said pull the covers and look for burned pins and such. While you are in there you may as well change the GP's and maybe even the O-rings. You may have a O-ring fail. Where do you live?

 

he musta posted in the SD forum as well guys.

here is the main thread.
