I have an 05 600 with about 1300 miles on her. I noticed last night that if I look at my K&N oil filter or even my drain plug I have a little bit of oil coming out of one and or both. The drain plug has the crush washer on it and is VERY tight and the K&N oil filter is about 1/3 of a turn past hand tight (I did put oil on the filter gasket so I don't think it's torn). When I saw this I went out today and got a new filter, crush washer, and oil and decided to change everything just to be safe. I did the change starte it up let it run for 10 minutes with no problems. I took her out for a 100mile ride come back and the same thing. Is this normal? I never had this with my Katana . . . . or well I never really checked.
