I recently sold a 1986 560 SEL. I purchased the car with 69K miles and sold it with 200K miles. I changed the oil every 3K miles with MBZ oil filters. There was never much oil in the metal canister. Just a few teaspoons at the bottom. The filter came with the copper washer for the drain plug, the alum washer for the canister bolt and a rubber o-ring washer for the canister top seal. It did sometimes make some valve noice very briefly upon startup, but nothing too loud.
