I made a contraption today that pulled 6 liters from my new SL in20 min!

Is anyone interested in this kind of topic?
Yup.

The only problem is that you still need to get under the car for the filter.

Exactly....

I have one I bought from Harbor Freight for the 129, which has the filter accessible from the top. I've not used it on the 107 for the reason you mention.

IIRC it was around $80 after discounts.

This is true. But I cheat a bit. Because I only do about 1500 miles per season, I only change the filter every other year. In between years, I extract the oil from above using a Mity Vac extractor. Works well.

One thing that is apparently different about our old SLs, is that the dipstick tube doesn't reach all the way to bottom of pan. At the dealersip, they use the dipstick tube to extract the oil on more recent cars. But on an old SL, even they would drain from pan. Not that I have had them do it!

I have to agree with MBGraham.

No method of removing the old, contaminated oil from an R107 is 100% (short of an overhaul), but I'm convinced the drain plug route is the most efficient. (But that's without benefit of seeing your invention, so I'll keep an open mind.)

But whatever the method, removal should be done (carefully) with the old oil hot, so that the most solid contaminants are still in suspension. And if draining is the method used, the hot, thin oil will exit more quickly and help sweep out as much of the heaviest, settled debris in the sump as is possible short of removing the oil pan.

Good road,

Bucket was obtained from wings and more, used to contain ranch dressing
Two 1" holes punched caddy-corner
Two 1" washers for top and bottom
1/2"-3/4" pvc coupling, enters from bottom
3/4" threaded female x 3/4" female non-threaded coupling, screw from topside
4"- 3/4" heater hose, inserted into the coupling above
rubber stopper drilled hole for irrigation hose
4'-6" 1/2" irrigation hose, inserted thru stopper one one end and into dipstick hole on other end

I slide the nozzle of my Kirby vacumm over the heater hose

This contraption extracted about .3 liters per minute.

I had considered fabricating an extraction device but couldn't figure a simple way to keep from contaminating the vacuum (pump or cleaner) with the used oil.

Using one of the pressure type vacuum pumps would work ok but then that would be exactly what I got from HF.

Don't worry, Jim. AFAIK no one is planning on pulling the plug on you any time soon. :D

You shouldn't have said "over my dead body" was the only way I'd get your AMG... :big laugh:

The word is "catercorner" or "catercornered." The "cater" is an Anglicization of the French "quatre," or "four," and "catercornered" originally just meant "four-cornered." To specify that something is "catercorner across" from something else is to stress the diagonal axis of an imaginary box, as opposed to saying "directly across" or just "across."

Thats sort of what the wiki link said. They did say catty-corner was a synonym, so tomjak was close :)

My bad

caddy-corner

CADDY-CORNER


CATTY-CORNER, CATER-CORNER, KITTY-CORNER


This expression, meaning “diagonally opposite,” was formed from a misspelling in English of the French word quatre (“four”) prefixed to “corner.” Although the word has nothing to do with cats or kittens, in various dialects all three spellings are acceptable: “catty,” “cater” or “kitty.”

But unless you have somebody holding your golf clubs permanently stationed in the corner of your room, you shouldn’t use the spelling “caddy corner.”
