Hello Everybody,
I hope you experts can assist with a question and guidance about oil filters.
I recently acquired 47 Custom Super (356) that is undergoing some work in a shop in the lower 48. I can't find a reference to an oil filter in the shop or owner's manual, although I have found references to oil filters as a Packard accessory.
Am I right in assuming that oil filters were not standard equipment for the '47 - 356? And if I am right, are they still available somewhere? Is there any downside to installing one (i.e. loss of authenticity, etc.)?
I am a stickler for maintenance, and will religiously follow the 1000 mile oil change regimen, but I should think an oil filter would be a good idea to preserve the engine as best I can.

Thanks,
Mark

i don't know about the 47, i have a 52. but i have an extra canister with lines if you can find out if they are the same.

A 356 being hydraulic lifters, you would assume the oil filter would have been standard equipment.

Thanks Big Kev,
I'll keep up the research. Appreciate it.

An oil filter was standard equipment on all 356 engines. The canister/filter was missing from my '50 Custom. I replaced it with a used canister from Kanter.

More details on the filter can be found here.

Edit:
The filter on a 356 should be plumbed in a bypass mode to ensure adequate oil pressure to the hydraulic lifters. This requires a 'T' brass fitting to accommodate:

1. Line out to filter.
2. Oil pressure sender.
3. Pigtail bypass out to lifter gallery.

Here's a photo of a filter in bypass mode on a 327 9 main engine... different engine, same concept.

Correct.Oil filters were standard on all Packards with the 356 engine.

Good advice from JD. I would like to add that you assure there is a restriction in the oil filter or in the "T" fitting. Restricted oil flow through the filter will insure sufficient flow and pressure to the hydraulic lifters.

Many thanks to Kev, JW, GTO and JD - you guys are great!

Not to be overly redundent, but there is a statement in the 1941 Packard Data Book, on page 101, that the One-Sixty (356) engine is equipped with a two stage oil filter and that it was an option for the One-Ten and One-Twenty.

Photo also shows the plumbing - see below:

One question would be the plumbing shown on that original 41 illustration. This threadhttps://packardinfo.com/xoops/html/modules/newbb/viewtopic.php?post_id=67387#forumpost67387 in post 31 mentions several service articles on rerouting filter flow because of noisy lifters. Weren't the post war 356s more in line with the later 8's as shown in JD's photo?
