I dont think you have anything to worry about. Sounds perfectly normal for a 170,000 mile engine. Mine smokes when I accelerate hard or go uphill. If your car is like mine, it is probably wound pretty tight at 68 MPH. Remember, we dont have overdrive. Im sure you just have normal injector nozzle and injection pump wear. I have noticed that mine smokes worse when I buy diesel at certain stations too. I get less smoke with Chevron deisel for some reason. Cliff
We don't have overdrive? We have four speed transmissions. I agree that the smoke is normal, both of mine put out a good deal (well at least one of them still does) of particulate matter when I'm on the throttle and especially at high RPM's.
Whoops! I am so use to my 4 speed manual trans that I forget about the automatics. I stand corrected. Cliff
It was dark when you saw the smoke? Illuminated by your tail lights and/or the headlights from the car behind you?

Additionally you don't see the smoke during the day? Correct?


Its just the refraction of the headlights thru your exhaust that makes it seem MUCH worse than it is. (unless you were flooring it uphill, in which case it probably was that bad)
Mine does the exact same thing. Visible smoke at night, invisible smoke during the day. Is your ALDA tuned? My car smokes less with ALDA at factory spec, but with 1 turn CCW, it smokes more.

On a funny note, on one night I once "smoked" a Mustang convertible (with the top down!) that was following me when I downshifted via kickdown. [:D][:D] He switched lanes and roared past me. I was laughing the whole time. [:D][:D][:D]
Thats what I do! When people are on my ass, I just nail it and let all that smoke go into there car and in there vents and crap. They either stay away or go around me.

I drive the 300D kinda hard, use Mobil 1 synthetic, use Redline, PowerService Diesel Additives, It had a Diesel Purge two weeks ago, and it hardly smokes. I had a tailgater today, and I couldn't smoke him the way I wanted! Oh well.

i was also disappointed last night when i could not smoke a tailing riceburner right on my back bumper.

[:eek:)]
too bad we can't turn a knob and make more smoke at will. I had some jerk tailgaing me, so I slowed down - he was driving 2 feet off my bumper, having switched out of the fast lane to try to pass on the right. I kept going slower and slower and downshifted to 3rd and floored it - smoked him good, he came around and was yelling, waving his pudgy arms - I was laughing my ass off!

That's EXACTLY what I would have done!!!! [:D][:D][:D]

We should make a score board for this! Tailgaters score the most points, ricers second most points, or BMW's third most, something like that. [:p]
a guy put a mod on his TD and could put out smoke
at will
