I can't recall seeing that much crud previously on a bypass valve with a posted dissection here, interesting. The rest of the filter looks like it held up ok though.
However, based on recent postings it appears O'R MG's are now going to be made by Champ, following the pattern of the Wally TLE oil filters which are now Champ made instead of an orange can. Basically the TLE's are Super Tech's with texture, meaning some are ecores.
