Probably going to get beat up for this question, but.........i have taken the oil filter out of my GS 80 but have noticed that no rubber seal that is supplied with the new filter came out with it. Also on the filter that came out it has "ox37" and the part number ends in 570, but the new filter ends 575 and has ox 36 on it. I know its a crap question but would appreciate any help re the numbers and the rubber seal with the new filter. I will buy a manual for future, but stuck at the moment. I have to go back to BMW tmrw for some plug washers anyway. Any thoughts please?

............oil filter and sump washer!!!
