is the light mist behind the car at night what youall call smoke? or should it be thick black smoke like freightliners on the interstate?
im a self-diagnosed worrywort and if its supposed to smoke then dammit, i want it to!
i had a bit of grey smoke that smelled strongly of unburned fuel but a new air filter cleared it up(?)
i was at the burger king getting lunch and the lady commented that my car smelled like a gas heater, there was an auto-parts place next door so i stopped before eating my nummie greaseball on wonderbread.
oh yeah and i lost the wing-nut to the air cleaner, should i worry about that? i dont think i dropped it into an open engine, though...

DAG-NAB-IT~!
THANK you for reminding me that my car has an AIR FILTER.
My car was always smokeless, even wide open throttle, until recently. Fuel economy has dropped from 31 mpg earlier in the summer to 23 - 24 mpg. Step on the go pedal now, and the traffic behind my tailpipe is buried in thick smog.
IT'S BEEN ALMOST 15K miles since I've checked mine....OH sure, change the fuel filters, replace lines, fasten clamps, check for leaks, clean switchover system, but I overlooked the most obvious. I'm sure the car can't breathe.
Any diesel is supposed to smoke a little. At night, heck, I can see smoke from my gasser at WOT. A diesel's emissions particulates are large, and thus the luminiscence from headlights exaggerates the visual output. It is normal, and it sounds like your car is in great shape.
Chances are the wing nut just dropped to the bellypan. Just go under and reclaim your nut. More than likely it has already slid out from behind, however. Get a new one at an auto retail store. Is that not the only bolt that fastens the cover?
