Decided to cut open the filter that came off the 2002 Tracker 2.5 V-6 I just got. Unknown mileage, but I'm going to guess its been on there a LONG time. Anti-drainback valve was pretty hard. Lots of carbon deposits (nothing was attracted by a magnet) you can see in the can/baseplate and what I scraped from between a couple filter pleats. Seems like a solid filter that did its job. This thing holds 6qts and only 2.5 came out when I drained it. Timing chain start up noise has been eliminated with new oil/filter. Fram extra guard PH3614 and Chevron 5w-30 synblend went back in.
