1984 300D No smoke!

Hi all and happy holidays. I have read all the posts concerning my make and model and have gained a tremendous amount of knowledge through this great resource. One thing that puzzles me is all the remarks about exhaust smoke. I don't know if I am just lucky but my 300D never spews any smoke upon start-up or running. The only time I can see anything remotely resembling smoke is when I really get on it at night and look at the headlights of the guy behind me. It is just about invisible during the day.

1977 280E Automatic Transmission doesn't lock in park ??

My automatic transmission in my 1977 280E does not lock when placed into park. When the car rolls with it in park it makes a clicking sound. I think there is a part on a transmission called a parking "pawl" and I think it jambs into something that acts as the lock. Don't know how it works on this car but I'm guessing that it must not be fully engaging and is the reason for the "clicking" noise if it's partially engaged. Please let me know if there is an easy fix for this. Thanks.

1981 300D Non-Turbo Veggie: Not enough engine heat

I've been struggling with a problem of my engine not reaching optimal engine temp under normal driving conditions (summer driving in the mountains always does the trick). On my normal, mostly flat drive to work I barely maintain 165 degrees in winter temps of around 40-50 with heaters going (which just barely keep me warm). Here are my specs:

White Smoke at Idle on WVO ('81 300D non-turbo)

I've been running WVO for three years without too much smoking. Now I have lots of white smoke at idle and low speeds after commute home from work. I've noticed this only in the evenings on my way home and not on my way to work, even though the conditions are very similar. This started a little after replacing the injectors with Monarchs that were professionally pressure tested. The other correlation is the recent onset of cold temps around 40-50F. A few other pieces to the puzzle:

1984 300D Turbo Water Leak

I have what appears to be the typical water leak which comes in through the front passenger side leading to puddling in the rear passenger side. I have cleared the drain holes under the hood and repaired the rust under the battery using the miracle paint and cloth method, however I still have the leak. It appears to me that I should replace the front windshield seal based on what I have read on this web site. Is there anything that I have overlooked or other areas that I should check to stop this leak?
