Re: Oil Filter Lines

Agree O-D, but for some reason they didn't put the extra oil return hole in at the same time so the filters had no choice but to be plumbed full flo the way they were. The pressure lube was a good thing but maybe they didn't think it through or didn't think filters were much of necessity then for those (or any) engines and wouldn't be used.

Possibly they realized they needed a different arrangement early on but they went on cycles with major core casting changes, so new line in 51 was the time engine blocks were completely redone--who knows.

Any idea when filters actually became the standard-not the option-and not only for Packard.
