I was going down the hill by my house a few minutes ago in second gear, foot off the brake pedal. All of a sudden, the engine/exhaust got fairly loud. Crap, I thought. The donut must have popped loose.
I got it into the garage and lifted the hood while it was still running, and of course, couldn't see anything obviously amiss...until I raised up and looked toward the back of the truck - blue smoke.
Does anyone have a clue as to what happened?
