But would it matter?

Pic of eCore with a hole in the filter media - look at that nasty looking plastic cage which supports nothing.

eCore experience - oil starvation

It was the same part number we've known and trusted for years. So we did a oil change on the car this spring with the new filter. We had driven it for a good portion of the day, some of it at WOT for a few seconds, when suddenly the idle dropped to about 500 rpm, and then the motor shut down. We tried to restart it, but now it had a rapping sound coming from the #7 cylinder. We pulled the valve covers off, but everything was fine there. We trailered the car home and took the oil pan off. Things were looking OK until we got to the #7 & #8 rod bearing caps. Both caps were blackened. We pulled the motor from the car and disassembled it. The rod bearings were roasted. The main bearings were junk too. Bearing material was all over in the bottom of the oil pan. It looked like a classic oil starvation event. We then inspected the filter. It looked a little strange. The filter media was coming out of the oil exit hole. We turned it upside down to drain it, and found that the new Ecore had collapsed inside, allowing the filter media to come loose and plug the oulet.


I don't know about you, but I would want a center core in the oil filters used on my engine to support the filter media - not have the filter media BE THE SUPPORT!

Those plastic cages - though it may cost less for the manufacutrer and you - look scary. And I wouldn't care who made it.




Many/most cartridge filters have another support that slides up inside of them when you install them into the housing.

Most of the E-core issues, IMO, are due to their bypass valve not allowing enough flow, rather than the nylon cage itself. I've dissected many filters that were on GM vehicles, and the media looked great. Those engines have an internal bypass and do not rely on the filter.

Could very well be the case ... that's why I stay away from ecore filters AND filters that have a "rubber combo ADBV/bypass valve" design, regardless if they are ecore or not.
