I just replaced the oil filter and now its leaking around the bolt at the top of the canister. I see from my parts book that there 2 seals on the bolt. Should I replace both? Any advice?

    Yea, change the seals. Not required every time but at that age--. I vaguely (and I do mean vague!) remember a service note to change those every third filter change or something

    That was it. I got 3 O rings from Cleveland Brothers and they didn't charge me. Thanks!
