I've had my Excursion since October - finally got around to putting the Wicked Wheel on today to solve my turbo stall problem. Anyway, after I got everything off, I noticed a bunch of things down in the galley of the engine that looked like wood chips (it was dark - couldn't really see well). I got the shop vac and sucked all the debris out of there and much to my surprise, they were cigarrette butts. Now, either they ALL landed there after being sucked up into the engine while driving down the road or the previous owner dumped them down there to soak up the diesel dribbles (or for whatever crazy reason) - anyone heard of such a thing? By the way, the truck only has 63,000 miles.
