gray smoke? lol give me a break. anyways, burning oil=black.grey smoke= lightly burning oil.
of course, could be pig rich. easy way to get that (I can duplicate this at will) is to force a vacuum leak, the O2 sensors freak out, trips the check engine light, and dumps fuel faster than you can burn it.
bingo black smoke.
another 'classic' valve guide tipoff is smoke on decelleration. Tach it to 4500 or so in gear (works best on a manual), then let off. got smoke?
btw, I definitely appreciate lightnings. don't know where you got that idea. I've almost bought one several times.
