Where can I buy the crush washer for the drain plug w/o having to go to the Nissan parts counter? Is there a particular size I can find at the local parts stores (Pep Boys, Autozone, NAPA)? Also, oil filters: I know there was a thread here on what everyone uses, but w/o having to visit Nissan parts counter (again), what's good that's available at the the above stores? Got some down time today (Sunday: Nissan not open) and figured I'd get it done if I can get the filter and crush washer nearby. Also: Anybody ever use those drain plug replacements that have a valve for quick emptying? Saw one that looked like you could attach some tubing onto the end and direct the flow off your truck and into your drain pan. If I knew the thread size, I could probably figure which one to get (no reference sheets for which vehicles they fit).
