That sounds/looks familiar. Here's the filter element from the Canton 25-184 mounted on my 993 filter housing that was installed on my 3.2 short stroke



It's this filter https://www.cantonracingproducts.com/product/25-184/25-184---CM-34quot-BILLET-SPIN-ON-FILTER-20MM-THREAD-2-58-O-RING/

The above picture was prior to having the massive bearing failure I linked above in post #10. Also note that the oil used in this filter was 30W oil. Point of mentioning that is a thinner oil like 30W would place less of a burden on the filter than would a typical 20W50

Seems to me a filter like this that filters down to 8 microns is restricting oil flow too much. Anything less than 30 microns, I believe, is too small anyway to create significant damage? That micron threshold is just something I recently read and isn't based on any sort of technical documentation/report.
