I picked up a 00' 426 recently for a good price, starts 1st kick and rips like it should. However changing the oil filter revealed a bunch of debris, imgur album below. http://imgur.com/a/vuPXi It seems to be a mix of steel and aluminum, but the black gunk and flakes escape me. Since its still kicking hard, I was planning on running it another 2 hours and seeing if there is a comparable amount of crap in the filter. But is that a sensible thing to do? Any advice appreciated, since im new to this kind of thing.
