Oil Filter Copper Gaskets

[IHateUserNames]

I was changing the oil on my father's 89 560SL today, and I have run into a snag.

When I removed the oil filter canister a copper gasket came rattling out, but I am not sure where from. I have the replacement gasket that came with the filters, as well as several other that came in the baggie with the big black o-ring.

Which copper gaskets go where, and how are they changed out?

Of course I didn't notice the gasket in the oil catch until after I filled the car (before I started it). How many quarts am I likely to loose removing the oil filter with the rest of the fresh oil still in the car?

You shouldn't loose more than the volume of the filter cannister, and unless you prefilled it or have since started it, probably none at all.

there is a copper gasket at both the drain plug and oil filter canister, however if it is not leaking , I would not worry about it, keep an eye on it however at intervals or just get an assistant , loosen canister while they hold i in position , quickly remove bolt place on copper gasket, retighten

Thanks. We will keep an eye on it and, if we see any leaks, try the quick switch.
