Chris and Crin:

Packard went to full-flow oil filtration on the Eights and Super Eights in 1934, along with the oil temperature regulator (sometimes referred to as an oil cooler) and finned connecting rod caps, these changes to add longevity to poured babbitt rod bearings which were in their last year of use. These engines used the Purolator L-6 but just for this year, 1935 thru 1939 used the L-8 version which differed only in how the oil lines were fitted at the inlet and outlet. L-6 connections were via female NPT threads, L-8 used a cap secured by cap screws as pictured by Crin. Both were of the disposable, sealed cartridge type with replacement recommended at 8000 mile intervals. The 1934 Eight and Super Eight installation is also unique to just that year, the oil temperature regulator is mounted directly to the water jacket side plate and the filter stands vertically, its outlet connected directly via an NPT nipple to the underside of the oil cooler, pictures of the 1934 L-6 installation follow.

I don't recall what the Twelves used in 1932 thru 1934 but in 1935 they joined Eights and Super Eights and used the L-8.
