    If its an automatic transmission, you probably need to keep the original and rebuild it.

    If its a standard transmission, you may have other options, but most would require some modification to work.

    Gut the stock filter and install a paper element. It works better. Also install a PCV system. These two simple changes keep the grit out of the lower end of the motor, and with the poor oil filter systems on these cars, it is the grit in the oil that kills your lower end (usually, rod bearings).
     
  6. What's on it now, a Carter BB? They used those carbs on literally hundreds of vehicles for years, you should be able to find a cleaner that uses a paper filter that will bolt on.

    You can cut a piece of appropriately sized radiator hose and make an adapter that'll let you use a 2 5/5" I.D. air cleaner. That's how I did mine.

    Those little Carters were on a ton of cars up through the early 60's in various forms. If someone before you didn't damage anything they usually rebuild pretty nicely.

    I like the idea of gutting the stock air cleaner and fitting a paper element inside of it unless you are doing a dressed up hotrod look to the engine. I'll have to measure it but I might have a decent looking chrome filter for it out in the garage that doesn't fit anything I have or will have. I checked, two inch inside diameter and it takes a foam style insert, kinda motorcycle looking thing.

    You might find an aircleaner top you like and make a spacer to fit it to the carb. That might be a simple tech thing for someone to do. Take a piece of something like 1/4 inch aluminum plate and cut a hole with a hole saw in it to fit the carb and then trim the outside diameter to fit the bottom of the air filter element. You might even be able to do it with a piece of s**** lexan or something like delrin or uhmw from the local commercial plastics supply house.

    I have seen it done somewhere either on the HAMB or one of the other circa-50 Plymouth web sites or forums.

    Basically you can keep the upper part of the air cleaner intact - the part with the steel wool inside.

    You modify the bottom half so that you can lay a paper element inside instead of having the pool of oil. Yes some material has to be cut away but since it is all on the inside no one notices.

    I run the 1950 Desoto (avatar) without a air cleaner and it shifts fine. I also have a 1952 six with a tip-toe and it ran without a air cleaner for a long while mostly because I forgot I had removed it. :D

    How would I clean out the top part that s|-|it is dirty? I think I'm going to go with an AMSoil filter and fab a gasket out of radiator hose hope that works

    Dude, you need to get an owner's manual! Everything is spelled out. A repair manual is good, too, but back in the day the owner's manuals did a fine job of instructing the owner on how to perform routine maintenance.

    To answer your question, you clean it out with kerosene or gasoline. Then you reoil it with a light engine oil. The oil on the steel wool catches dirt in the air as it gets ****ed past. The rest of the dirt gets caught in the oil bath because the air flow has to do a 180 to get into the carb throat. The dirt in the air, being heavier, flies around the outside of the curve and so gets stuck in the oil bath. Great idea, simple to maintain, not dependent on an aftermarket parts supply chain; they just don't work quite as well as a modern paper element (especially once the oil starts getting 'full' of dirt).
