DougC 2,641 #1 Posted November 25, 2015 Just finished oil and filter change on the well used and abused 1988 520H and got the loose oil drain pipes tightened up to stop the constant seepage and noticed of course the rubber ring that goes over the oil filter to seal up the air flow to the inner head is missing. Does any of our vendors or forum folks have those for sale or do I need to try the dealer and hope it has not been discontinued. I hate to use it until I get that seal or grommet or whatever it's called installed. Share this post Link to post Share on other sites
