So much for the usual collection waiting to blame the Pure One/Purolator construction for the issue. Considering what is now known, the P1 held up darn well IMO.
Was going to say this sooner but now is a better time. For those saying 'oh if this had been an ecore'.....yada, yada, yada. I would like to see how an ecore design with felt endcaps and open nylon cage would have held up to the coolant leak. My bet is likely similar to webfors(sp) posts with a huge hole or holes, blown in the media. And, I'm not nearly as adamant against ecore as some, having used the ST #3614 before with no issues. But, since many were speculating about the P1's construction being at fault, just sayin.
And as for any Honeywell design with fiber/cardboard endcaps, one can only imagine the distortion of not only the media, but the 'engineered media' endcaps as well. All in all, another example of why I'll take the Classic oil filter design with metal endcaps, my choice being Purolator.
To the OP, sorry you had an issue, glad you found it. And, thanks for the follow up pics confirming the real problem. It apppears the folks pointing to the LIM gaskets, not the filter, based on what it did to the P1, were right on. Kudos to those folks.
