Yea, the wavy pleats are throwing me for a loop, haven't seen that before. Otherwise it looked ok -- no cuts or tears in the media, the louvers were good.Doesn't look awful. I remember when these were the darling of BITOG.. I just don't understand why they pleats are always so wavy... Thanks for the C&P.
Wavy pleats show up on a lot of filters that are cut open and shown here. As long as the media doesn't tear, it shouldn't make any difference, except visually.Yea, the wavy pleats are throwing me for a loop, haven't seen that before.

It's an end cap "popper".Just to be clear that is a metal top & plastic bottom base?
What you are seeing that looks like a "plastic disc" is the black potting material that was once adhered to the metal end cap. This has been a "Purolator thing" (the metal end cap pops off the potting material) for many years.That's interesting. I've never seen that before. They glue the filter element to a plastic disc and then have a detachable metal cap.
It's the black potting material used on both end caps. The end caps are suppose to be firmly adhered to the media pleat ends by that black potting material/"glue", just like any other oil filter with metal end caps. Have also seen a few Motorcraft filters that "pop" an end cap just like this one did.ah, that makes sense. It may even be some other material, other than plastic, on the plate that sets into the dome metal. Almost like a end plate within an end plate.
The cartridge filter media I cut up today was melted into the end plates. I'll peal out the end caps out of the trash tomorrow to get a pic of what I saw today. It's probably the same as your talking about except mine don't use any other end cap.It's the black potting material used on both end caps.

On the OP's Purolator, the potting material isn't melted, it's a thick liquid that dries hard. It's essentially a thick liquid glue.The cartridge filter media I cut up today was melted into the end plates. I'll peal out the end caps out of the trash tomorrow to get a pic of what I saw today.

Looks good. What went back on and in? Thank You2005 Tundra 89800 miles, 5300 mileage on the filter and oil. Unknown oil brand & weight, was over half a quart low.
Moisture (water) in the oil. Blow by condensate. Swells pulp component.Yea, the wavy pleats are throwing me for a loop, haven't seen that before. Otherwise it looked ok -- no cuts or tears in the media, the louvers were good.
Winter short trips can do it too-oil never gets hot enough, engine warms up somewhat, cools, dampness accumulates. Even a stuck open thermostat can do it (the MGM in my sig had a bad ‘stat & did that when I bought it).Moisture (water) in the oil. Blow by condensate. Swells pulp component.
It's the new WAVE ( craze ) of oil filter production .Yea, the wavy pleats are throwing me for a loop, haven't seen that before. Otherwise it looked ok -- no cuts or tears in the media, the louvers were good.
