That is indeed an insane amount of metal in the filter - really really insane for 44 miles so what like an hour of run time????

I agree I almost have to say the worst it has to be bearing material.. I cannot see that amount of debris coming from the distributor bushing. I would drop the pan you will probably find even more and bigger chunks in the pan and pickup, and if you pull main and or rod bearings you will find damaged ones I bet...
