Purolator oil filters - need to identify.

With the sealed can type be careful, many of them are"bypass type" with small, restrictive openings rather than the "full flow" type that accepts a greater volume of oil.

I once had a '51 Chrysler Windsor with a can type filter and I replaced it with a similar looking one with the same thread sizes, immediately after that I noticed the oil pressure dropped and the motor made strange knocking noises during acceleration, I soon discovered the difference between "bypass" and "full flow".

Of course I was 16 at the time and nowhere near as ignorant as I am now!! grin.gif

My February 1932 Purolator application list does not include the S-4 it only goes up through S-3, it does however list the SF-3. The SF-3 was used on Packard 640 and 645 from Oct '28 to June '29. This comes from: PurOLator, February 1932, Form KS-7, Printed in the U.S.A., Licensed under Sweetland Patents.
