Whitish Gray Smoke
Hey guys,
I just picked up a '97 Powerstroke about a week ago. It's been running fine, or at least I think it has because I got it checked out by a mechanic before I bought it and got the green light. Today, I was out in front of my house and was revving it a bit and noticed some whitish gray smoke coming out of my exhaust. I had my wife come out and she said it was whitish gray mixed with some black. Now I know that the black smoke is unburnt fuel, but what causes whitish gray smoke? Also, the truck has a 3" down pipe into a 4" straight pipe and when I'm getting on the throttle (when buildings are next to me I hear it best because of the reverb) but it sounds choppy coming out of the exhaust. Choppy may not be the best word to describe it, but it just doesn't sound super smooth flowing; however, the turbo whistle still sounds nice and smooth coming out of the exhaust. I was thinking it could be a bad injector to make it sound sort of choppy, or is that just how Powerstrokes sound? Sorry for multiple questions, but I just figured they may be related because if it is a bad injector, I'd expect some smoke out the exhaust; however, I have no check engine light on which I would expect to have if I had a bad injector.
Any help would be greatly appreciated.
