oil bath

air is drawn into the unit, passes the oil and looses the particals. The oil will be all over the unit (inside) and the metal mesh on will grab the oil after which is will drop down.

A number of people have changed the filter to an air filter.

Cut away the mesh and depending on the unit use a (fitting) paper filter.

Make sure the opening at the top is sufficient for breathing.

Mike:

I replaced my old oil bath mesh filter with a Napa Gold paper filter. When going to a show or just a cruise in in run witht he paper filter. If the car is being jusged then I take the orginal with me and then take the paper filter out.

The paper filter is better then the old oil filter and you do not have the oily mess to deal with. Just measure the inside diameter and outside diameter and the height of you orginal filter, You might find one with the same size at nap or very close.

I must disagree. In my humble opinion the oil bath filter works better. But you are correct it is a mess to service.

And Mike, You have taken way too much time to make up your mind on the fender chrome. I was only home for a week and now I am away from home for two weeks so if you say yes now it will be a long time before I can ship this to you. I would have thought you at minimum would have had the courtesy to say yes, or no thanks, but you did neither. You seem to ask all these questions, get good answers, but never respond to good answers? I am not sure when the next Barret Jackson auction is scheduled but if you plan on having your car ready you need to act now.

Oil baths do an excellent filtering job -- in the old days and especially today with the air so much cleaner. If the top half with the metal mesh is dirty, soak in kerosene to clean it up. Unless you drive a lot on dirt/gravel/construction roads, the oil bath will do a great filtering :)job. Keep it filled with 40 wt. oil.

actually the viscosity of the oil does have some bearing on the filter's operation. The recommended weight is to assure that whenthe engine is running a certain amount will be pulled up onto the metal mesh, where it functions to further trap small particles. when the engine is shut off, those trapped pieces are supposed to return to the reservoir when the oil drips back down. Designed to make the air flow make acute turns, the larger particles are supposed to drop out of the air stream when it makes the sharp turn.

So if the oil is too thin it will be sucked past the metal elements and into the carb with its entrapped particles (not a good thing) if it too thick, it will not be drawn up and the mesh will not do its job dry, also not a good thing.

Contrary to popular belief, the air does not actually pass through the oil in a properly maintaned and serviced filter.

Wonder why a lot of heavy duty construction equipment still had oil bath. Maybe because it works better, and clogs less frequently in extremely dusty environments.

Still running my oil bath breather, it was soaked cleaned, and painted and 15w 40 oil added, been using it 2 years about 3000 miles on it now, how often should it be cleaned and re-oiled.

While were on this topic, what about the oil filler breather, how often should it be cleaned and oiled?

Mine is clean at the moment, but I do drive 3 miles of gravel road to pavement everytime I take the car out....Fred

I generally clean mine whenever I change the engine oil. Maybe it is more often than needed but it really only works out once a year to me as I change oil in the spring. I actually left the oil in my '38 this year as it was extremely clean and in a heated garage over the winter so no condensation.

how exactly does the oil bath work?

In the book you ordered, the oil bath cleaner is not part of the carb section nor in the engine section so I guess you may be having trouble finding it. Look in the lubrication section of the book for the Theory of Operation, service procedure and periodic maintenance schedule..

Oil is a pain to maintain, old myth. Because 99% of our driving is on paved roads you really don't need to service them very much at all any more. I've had one in my truck and after a year the oil is still clean. If your on dirt and dirty roads it a different story. My off road bike uses an oil saturated foam filter, in some ways like the oil soaked filter material in a oil bath filter.

I believe the actual fluid dynamics is when the air make a 180 degree turn from the inlet lip back up to the filter material, the dirt due to the higher density than air, can't make the turn. As a result it collects in the oil at the bottom of the filter. The horse hair filter at the top of the filter is a secondary and final filter.

Ruth and those that want to see the modern air filter

In the old days when our car were being used we did have a lot of unpaved roads and this is why the oil bath filter worked very well to collect the dust from getting sucked in to the engine.

Hench with most of raosd now being paved excet for the ocassial county dirt road upto a fram or back into a forest etc we have changed over to the modern paper elelment. Yes some of you will state then why does KD have the new paper filter with an oil. This is is being used to make a new product again. I like paper because of the lack of the mess and oil that is my personal choice for a driver car but i still keep the mesh when having it shown at a car show.

Here are picture of the paper filter in my 39 Desoto.
