Black smoke, then gray/whiteish?

[leathermaneod]

Hi all,

so im not sure but I may have a new problem creeping up on me. Last few days I've been enjoying having no major truck problems and running with the smarty on 5 and timing advanced to have a little fun. I like to get on it a little in 3rd and 4th when accelerating and watch the smoke a little bit. Anyway, today it seems like as the smoke clears up it gets a little gray/whiteish. Now I should point out that it is wet out today so it could be just spray. But if it's not road spray, what could cause this?

I wouldn't worry about it.  I am assuming your truck isn't surging?

Nope, as far as I can tell everything is tip top for once lol

thanks for the reply!

I've had grayish white smoke on my first gen for about 200,000 miles.

The gray whiteish smoke means ur actually efeciantly burning the fuel,  black smoke means running rich, mine in stock form will smoke some black when getting in it till the turbo spools then turns gray whiteish  its normal as long as its not blueish
