Some of the oil removal devices you've shown us are for "Marinized" (Chevy,
Ford, Chrysler,Etc. engines with or WITHOUT heat exchangers)
They may or may not have a "Marine" setup wherby the Dipstick is plumbed into a fitting to make it the LOWEST point in the lubrication system.
This form of system (because you cannot access the oil pan drain plug) will work without any problems!

The 602.962 does not have this sort of adaptation (The Gnomes of Sindelfingen in their infinite wisdom never intended this motor for Marine use)[They like to use M.T.U.s . Marine engines purpose built from the crankshaft outwards]

'Get a set of ramps ... Get the oil HOT(30 minutes of driving)...Put the W124
up on your ramps... pull the oil drain plug ...loosen the filter cover ,remove
the filter... Vanish yourself for 30 minutes minimum...If after 30 mins. oil is
still dripping out of the drain hole ,go away for 15 minutes more [or work on
one of your other routine maintainence chores]...replace the drain plug to
Mercedes torque specifications(with a new crush washer)...install new oil
filter and filter shaft "O-Rings"...refill with oil...check oil level after reaches
operating temperature.

AND get to SEE the underside of your Mercedes to check for any problems!
