Can anyone tell me what the proper oil filter to use and look somewhat authentic on my 70 442? I looked up Year one and they have 4 listed. PF24 (blue)
PF25B White (looks oldschool logos) and PF35 (longer but looks oldschool also). They also have a K&N
When I asked Year one they said the PF25B and PF35 were for 6cyl, which didn't come in a 70 442......

Any help would be great

I use a WIX FILTER... Same one fits most of the straight off the block filter mounting housing.
There is a short filter, and a long one.
I'm from the old school... more oil in the pan, the cooler it runs, the better it works.
I have EARLY Tornados pans on my 65 ~400, & my 1970 442, 4 Speed, 455 motor.
Both cars hold about 6.5 quarts... The Boat has a Mondello 10-quart pan, and I use the same long
filter with that motor also. I have a 455 in a 16' ~ 1973 Marlin Gemini jetboat, that I mounted a remote
adapter on the passenger rear Cylinder head to make changing easier.
I'm sorry I can't remember the pat number...It digits... (49532) Maybe?... Sorry it's not a number I think a lot about.
BTW.... always use an oil that has High ZINC CONTENT IN IT. I've been using 20-50 Valvoline HIGH ZINC...SAYS IT ON THE 5 QUART JUG AT O'Rielly's IN Wareham Ma. If you have a Flat Tappet cam and lifters, low zinc or NO ZINC, you're asking for trouble... Old time experience talking here.
Good luck.

Since a lot of you read the threads, I have a question for ALL 442 enthusiasts.
I purchased at a car show in Dedham Ma, Endicott Estates Car show, Summer of 2022, ...
an Air Filter BOTTOM HOUSING for a W-30 car.... THAT IS CHROMED. I'm 67.
I've had about 8, or 9 - 442's, and raced them all, and gone to more car shows than you
an imagine.
No one has ever seen one in person or seen one online. It appears to be a factory part.
UNLESS it was done by a chroming company.
It's as close to perfect as a brand new one. All Holes are there...The chrome on the valve
cover vent holes are rolled and not sharp edged. The Auto Therm valve, and the round attachment
for the heat riser tube is there, even the Flapper door vacuum line bracket is tack welded on.
It looks like A Factory Part.
HAS ANYONE SEEN ONE OF THESE.
Fusik hasn't, and OPG had no one who knew or really cared to answer the question.
My next step is to ask my Fellow Olds Fanatics. Pictures are available, just call, I have them on my
cell phone number : 1-508-367-6661 Massachusetts
Let me know, Thanks in advance, David... Jet Boat Dave in my home town... Take Care
