W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

Diesel blow by, high oil consumption, why?

I recently purchased some of your manuals and was checking out my newly purchased 82 300td and noticed it has excessive blow by and was 3 quarts low on oil after roughly 1000mi! I did your plug the breather trick and it goes for 3-4seconds before shutting down. This car starts great on frosty mornings and has lots of power, no smoke and no oil spots on the driveway. What do you think is the best method for freeing up sticky rings? (if that's my problem) I have a friend who fills his crankcase with biodiesel after draining the oil and idles for 10min or so. Do you think this is a bad idea?

Electrical and wiper problems 1993 300D

I have a 1993 300D 240 turbo with a few issues I need help resolving. The windshield wiper doesn't work. I have attempted to remove the shroud below the windshield and can't or haven't gained access to the motor. Help I also have an electrical problem with the drivers headlight. I have high beam but no low. I have switched the bulbs with the passenger side and bulb is fine, fuse is fine. What's the next step? Don

1983 300SD touchy wiper switch issue

Wiper/Indicator Stalk Issue My 1983 300SD thinks that it has automatic wipers! Some instances when I use my turn signal, the wipers intermittently wipe the windshield and will continue to do so until I jiggle the switch or use the turn signal again. It's really quite frustrating and has started to noticeably scratch my windshield!

Transmission issues on '77 300D

the battery died on my 300d. I had my father-in-law pull my 300d home with my F250 (with tow-strap) about 7 miles. I put the 300D in neutral (AT) and about 1/3 the way there, the speedo cable broke. I finally got it running and now the auto tranny seems to be slipping a little bit from going 1st to 2nd, and from 2nd to 3rd. Any thoughts/suggestions? I'm ordering an "Early Auto Tranny service kit (1)" from you guys anyways. Any advice on the speedo cable? I'm using my GPS for now to tell me how fast I'm going. Thanks!

115 front seat belt issue.

Hi all I'm in a bit of a fix with the local car authorities. I currently have 2-point seatbelts in my W115 (one near the shoulder, the other in the middle of the bench seat). They are saying that I can fix a 3-point seat belt in my W115 and consequently refused to let me renew my license until I change it. My mechanic though is saying there is no where to bolt the third point (somewhere under the shoulder). Can anyone confirm which of the two is right? Mark

Will a 115 motor bolt into a 123 chassis?

Saturday I bought a 1970 220D as a parts donor for my 1975 230-4. I didn't know it had a good running motor. Now I'm trying to find some way to make use of it. I just can't throw something usable away! I do have access to a cheap 1978 300D with a siezed motor and good trans. Question is will the engine fit the chassis without major fabrication and will the 300D trans bolt to the 220D motor?
