W123, Diesel Engine Repair

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?

I see three place for Senders for water temp guage #1 on the Engine block (drivers side) #2 on Water housing (passenger side) #3 On water housing (on front of engine) 1) Which sender feeds the instrument temp guage? 2) Can I check to see if the problem is guage or sender by grounding the wire goiing to the sender ? (will the needle on the guage move?)

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!
