For anyone who has never had filter collapse(spelling) the most usual sympton is oil pressure drops to about half of what engine normally holds then if you bring rpm up it goes to zero.
If using throw away use racing or hp type

Moroso makes a screen that lays in top of filter (chevrolet) there's another company that makes some for other applications can't think of brand name, but these screens work really well for keeping eye on engine without cutting filter apart.

They will show particles of stuff you will never see by cutting filter apart and inspecting,if you've ever used O'berg style filter they are like that, but just lay in top of spin on filter.
