I recently bought a 1954 Convertible.It has the correct factory Air filter but while working on the car, I noticed it was converted to a paper air filter.The one in there only goes about 1/2 way up so essentially it is useless.Has anyone out there ever done a conversion and if so, what paper filter did you use?

GTO, maybe you will be able to find the correct oil bath internals? Though they do present an occasional maintenance chore it is a more efficient air filter than the paper elements so in the long run, probably better for engine life. If you had a simple oiled mesh rather than the oil bath, then I'd stick with the paper element as it's superior to the oiled mesh as used in the more junior models.

Here is a thread from earlier this week on a paper element air filter. Let us know if it works on the 1954.

Packard 1948, that conversion you referenced was an oiled mesh air filter, a very different and simplistic piece of equipment compared to the more sophisticated oil bath which is what GTO needs. Though the units are a bit different in 51/52 (illustrated below) in appearance, they function the same as the earlier units. The upper type simply uses a lightly oiled mesh to trap particulates. The oil bath type (lower image) has the mesh partially immersed in motor oil and forces the air to make several 180 degree turns before passing thru the media. The particulates, being heavier, can't negotiate the rapid turns and end up trapped in the oil. Hope this helps you understand the differences.

GTO, congratulations on your recent acquisition. I admit I'm biased, but you've got a winner there! Fortunately, my original oil bath air cleaner assembly is intact and I'm keeping it that way. If I faced the situation that you're facing, I wouldn't go for a paper filter. I'd look at a K&N filter; they don't use paper, they use an oiled cotton material that's supposedly far superior to paper. Their filters are built to be washable and reusable so you won't need to replace it at a given interval. On their website, www.knfilters.com, you can search their product line by dimension. Once you determine the filter's outside diameter, inside diameter and height you can see what they offer. They manufacture in many sizes so they most likely would have one you could use.

Well...you learn something "old" every day...

GTO, here are some photos of when I installed a modern pleated paper filter element in the oil bath housing of my 47 Custom. I saved the original filter element in case I or a future owner wanted to restore the oil bath function. I don't recall the filter part number, but it is a common size.

JW, thanks for the tip. I just went up to the shop getting GTO's car ready for the highway and took it on a nice test drive - it's an outstanding car! Unfortunately the 54 senior air filter is very different from the one used on the 356 engine and won't come close to fitting. But we do have some measurements so GTO can go shopping for a paper element while he tries to find a correct oil bath unit.
