Well this filter gave me a pretty good fight. It would not come off, so I took my Fram pliers to it. That explains all the dents. Still wouldn't budge, so I finally bought a filter wrench at AZ and that got it off. Unfortunately, my squeezing it with the pliers compressed the can in parts, hence the dents. The dents trapped the center core with the media, until I took a hacksaw and cut it lengthwise, and then peeled the bottom back with snips.
All I know is that a friend of the PO took it back to the mechanic who changed the oil & filter last, but was told that there weren't enough miles on the oil to change it. So this was in play for several months if not a year or more; probably not 3-4K miles. But even that is conjecture on my part.
A few points:
1. There was at most a few drops of oil that came out as I took it off the engine block. Now it does sit upside down on the engine block on the Camry in my sig, but I was thinking that the nitrile ADBV must have stiffened. I was surprised that it was as supple as it was in my fingers, but there was very very little oil that came out as I cut it open.
2. My main purpose in doing all this was to see if there was any sludge or evidence of a gunked up engine. The 2.2L 5S-FE was on the list of engines Toyota had to settle with in that sludgefest 15 years ago. I was surprised at how little gunk there was in the pleats. Not only did I saw the top off, and then saw it down the middle to extract the center tube & media, but I also dropped it in the dirt.
3. If you see any damage to the media itself, just assume it came from the sawing, I also inserted a screwdriver down the can because the dents trapped the center media & tube inside for a while.
I put in a frankenbrew of oils (at least 3) that will take it about 2500 miles to the 280K mark, at which point I'll start 5K mile OCIs. I have a Fram EG4697 (OEM size) on it now. I'll cut that open to verify, but this is looking like there is no sludge if any in the oil. If the Fram EG looks as good as this, I'll go 5K on oil, and 10K on a Wix.
