Filter collapses do happen. Could be due to defect or a pressure-flow problem. Test oil pressure with gauge to make sure the relief is working. Did you install an oversized pump on this engine? (Refresh my memory). If so the stock relief can't handle the extra volume of a cold engine when revved too high. This will over pressure the system causing filter failures, valve float from the lifters extending and at some point even a shears off pump drive. The overpressure will expand the filter can causing the element to come loose. Test the oil pressure engine cold and rev it up. You want the pressure to stay below ~ 70 psi.

Greetings,

    In preperation to relocate the oil cooler I found the filter element
inside the FRAM 2870A cartridge had collapsed. The inards were blocking
about 80% of the outlet hole. An autopsy revealed the element looked like
someone had stepped on it. Instead of round it was "C" shapped with the
failed side now blocking the outlet.
    On a possibly related note; this engine has had lately a high incidence
of lifter ticking on start up. This was puzzleing since this engine only
only a few thousand miles since rebuild.
