FINALLY got around to cutting the filter open. Nothing unusual to my surprise. Why that crap was stuck around the drain plug and not in filter is weird to me. I will say the K&N Filter appeared to be very good quality inside and the anti-drain back valve definitely worked as it still had a bunch of oil inside despite having been left to drain for weeks.

p.s. Car has been pretty quiet lately! I'm wondering if something was in a container of oil from production. I guess it could happen. I'm going to do another oil change sooner than needed and see if there's anymore of that plastic like crap stuck to drain plug this time. Sometime in near future I'll put water pump in it as preventative maintenance (been over 80k since and who knows how many idle hours) and probably pull timing cover while in there. That's of course if things keep going well and i don't suddenly go back to CLACK CLACK CLACK....fingers crossed.
