W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

1984 300SD smoke during Wide open Throttle (WOT)

Hey guys and gals.

1984 300SD
142k miles
I have had it about 8 months
I have changed both fuel filters and purged about 5 months ago.
It has a fairly fresh oil change and filter about 3 months and 3500 miles ago.

It starts and runs very easily and well.
It kicks down and shift correctly (sometimes a little jerk on upshirt but really minor)
All my vacuum stuff works

When I drive the car it start and warms up to 1/4 the way above 80deg on the temp gauge and stays there if it matters.

82' 300d still not charging

My 82'300d was not charging so I replaced the battery removed the alternator had it tested and it checked fine. The tension nut was missing and the bolt was gound down from rubbing on the pulley so I replaced the bracket, bolt, nut and installed new belts. It started right up and everything seemed to be fine. That was 10 days ago and now it's not charging again. Any suggestions? I'm stumped, any help will be greatly appreciated.

84 300d switching out odometer

At the time that I bought my '84 300D recently, the spedometer was inoperative (pegged to max) and a few of the other instruments did not work (although the odometer did work), so I sent the whole cluster off for repair and bought a used cluster in good operating condition (for $25!) and installed it. Now the repair service has sent back the old one saying it can't be repaired (they only work on later electronic instruments). Problem is, my car has 124,000 actual miles on it, as indicated by the original odometer; and the replacement cluster came from a donor car with 277,000 miles on it.

1982 300 TD Conversion

Ok - I installed the kit - have no oil leaks and no audible vac leaks this Sunday. Monday I was running 90% pure diesel with 10 % veg oil. I drove over 75 miles with no problems whatsoever. (As it was such a small proportion of veg oil I did not believe I needed to switch on the heating element.)
This morning the temperature probably dropped to about 45 degrees. I live in the Bay Area and usually it does not get too cold. Again thinking that the high proportion of diesel would again not justify the use of the heating element I started and drove off. My car seemed to have about 40% of the power it normally has and 50 yards later stalled and came to a halt.
I checked all lines and the clear in line filter and saw no debris or leaks.
