clunk clunk when tranny downshifts when not under load

I have an 81 300sd with 334,000 on it. Have changed the flex plates and recently had the driver's side rear wheel bearing looked at because i was experiencing a clunk when i put the car in reverse. The mechanic said the bearing was going, but tightened it up and now the clunk is better ( a temp. fix... part is on the way...) but i have been noticing a 2 stage clunk when i accelerate after the car warms up. if i depress the accelerator quickly and let up quickly it clunks on the depression and release, also when the tranny downshifts when there is no load on the drive line, like when i am coming to a stop going up hill. any clues?

Purpose of diesel hand primer pump?

On my '78 300cd there is a hand primer pump on the fuel line just upstream of the main fuel filter. Does this pump run continuously while the car is on to draw diesel from the tank? Or is it just there to act as an emergency hand pump if you run out of fuel? I am trying to determine the appropriate place to cut in my svo line.

Crank shaft pulleys fell off!

Mayday mayday!!!!!My crank shaft pulley sheared the bolts that held it (the pulley itself) to the crankshaft! There is a large bolt that appears to hold the flange that the balancer and pulley is fastened to. Is this correct? If so can I remove the large bolt to remove the flange to make the repair easier? Sincerely arcnspark

Center vents barely blowing

Can anyone PLEASE help me? I recently got the A/C working on my 1983 300D, but the air barely blows out of the two center vents. The air will blow strongly out of the far right and left side vents, but not the center ones. If anyone can provide me with possible reasons and/or solutions to this problem, I'd be GREATLY appreciative.

If you'd like to email me directly, my email address is maptgpkrp@msn.com

Thank you VERY MUCH!!

WVO-Which types are best?...

In my limited experience with WVO I have encountered several kinds and types out there, It seems that it is universal knowledge to stick with what originally was 100% pure oil of some kind and to stay away from the hydrogenated stuff. My question goes further... I like to know what are the better WVOs? and what kind of WVOs to avoid?. Maybe on a "TOP 10" format. Corn, Soybean, Rice, Cottonseed, Canola, Peanut, Palmoil,etc,etc,etc. If there is any written information about this please refer, this will help all current and future lipid users.

water behind passenger seat, window?

I have after a rain a large amount of water behind the passenger seat. There is a large rusted out area by the right side front jack point. Also the front passenger window sticks when going down and comes off the track. Are these all related? Do you think the water is coming in from the jack point, door, or some where else? None of the seals have been replaced and the car has 202,000.
Thank you.
