The end cap folded over-but I didn't see a hole into the center tube(?) Many Toyota filters have no end caps at all, so maybe it wasn't a huge deal... BUT, wrong filter+wrong bypass PSI+fiber endcaps=asking for trouble!
WCW: Fram TG6607 with damaged end cap

Can't recall seeing an EG/TG like this one before. Yeah, it's not the spec size, but I've seen posted here where a quick lube has consolidated the 9688 to the 6607. In any case at 3k miles, imo shouldn't look like topic. WCW seems to think manufacturing error, weak glue job. Another 'First Brands' manufacturing effect result? No bueno.
Proprietary pulp fibers glued together.
Wrong filter for that application.......

Maybe not the best time to be frugal.
Which Fram always claimed bonded better to the filter media than metal end caps.
There are external circumstances but a filter should stay in good shape even if the media gets loaded. The 13psi bypass would take pressure off the media sooner than an OE filter. Also, paradoxically, because this filter is smaller both in height and diameter, the media should be stouter than a larger filter with more pleat height and potentially depth.
Filter integrity against bypass and pleat "geometry" and "stability" are the focus of manufacturing by the quality filter manufacturers outside of the US. Meanwhile the major US filter manufacturers focus on cost cutting and marketing while ignoring quality issues.
I noticed, something's wrong with that video. When he opened the oil filter it was bone dry. It should have leftover old oil one way or another but when he opened it nothing came out except parts of the oil filter. I think it was edited

Good eye Escape08, I also see dents in the top of the can, not sure what kind of rough treatment would cause that? Something is going on here?
Simple explanation. You can drain the oil out of a filter by pressing down on the ADBV through the inlet holes. I do this before I cut open a filter or if I don't cut open a filter, I do this anyway to better recycle the oil and filter.
The person who sent him the filter may have thought it was a good idea when mailing a filter or WCW finally realized he could have less mess if he did it before cutting it open.
Could be moisture related. If you look closely on the WCW video, the ends of the pleats where the end cap came off still look sealed, like the end cap just delaminated and left a thin glued layer on the pleat ends. The end caps seem softer than normal, so that combined with lots of oil flow going towards the bypass valve due to the loaded filter caused that end cap to bend and fail. Note how it's folded in the same shape as the cutout in the leaf spring.
A lot of oil flow around the upper end cap shouldn't put much upward force on it, unless there was poor clearance between the end cap and the canister, causing high dP across the end cap. It does look like the upper end cap is larger than the lower one. It's hard to tell from the video how much clearance there was, but it doesn't look like a lot.
Another user here posted an example of an Extraguard with end caps that were too large. In that case it was a lower end cap and it resulted in engine failure. This is the main risk with these fibre end caps. The quality control on them is pretty bad.
Could be the wrong oil filter was installed....
If the glue job was bad, and/or the end cap material degraded and delaminated, it might have happened even if the end cap to can clearance was normal and the media clogged and cause high flow through the bypass valve. Yes, if the end cap to can clearance was tight, it would definitely make it worse if lots of flow was trying to move towards the bypass valve.
It looks like there had to be a lot of flow past that end cap and through the bypass valve even after it started bending. For the end cap to completely bend over that much and take the complete shape of the leaf spring cutout there had to be a lot of flow going on. I mean once that end cap bent over even half way you'd think there should be a lot of flow area by then if the media wasn't producing high dP and the end cap would stop bending so much, but it bent totally into the leaf spring cutout. The media must have been very clogged to cause that much flow through the bypass valve.
Yes, if end cap to can clearance is too tight it's not a good situation. Fram use to put "nubs" around the edges of the end caps (at least on the base end), or have slight diagonal cutouts to ensure it was centered and had adequate flow clearance. Looking at the TG in the WCW video, I see no obvious nubs on either end cap. Probably another cost cutting move.

The KEY word is MIGHT.......It was the wrong filter for that vehicle...Its that simple.....O my car did not stop as good because I installed the wrong pads...My car rides funny.. I installed the wrong shocks....My car is not running right..I installed the wrong gas filter....Ect ect....
OK then lets just install wrong parts on out cars and trucks then complain about it not running right...I cant believe this forum is actually complaining about this oil filter that WAS installed on the wrong vehicle in the first place... I guess you bash a certain product all of the time even when the filter was installed on the WRONG vehicle....
I analyze ("bash", lol) any filter that shows an obvious failure like this one, or has crap manufacturing quality, like leaky ruffled leaf spring stampings. I gave my analysis on this one, and this failure is not solely due to the slightly smaller size of this filter vs the specified filter. Could be a factor, but not the sole factor. There are other larger factors involved. It's not solely because it's a slighly smaller sized filter.OK then lets just install wrong parts on out cars and trucks then complain about it not running right...I cant believe this forum is actually complaining about this oil filter that WAS installed on the wrong vehicle in the first place...
