Several companies have replacement oil filter bases that are billet alum.,I never have had one of the GM cast ones fail,but billet ones are probaly good ideal and not bad cost,I need to order some instead of digging out GM cleaning it up and plugging bypass.
I always plug the bypass (racing)does'nt take much pressure to open it,and have some unfiltered oil
I know Canton,Moroso also have them
