Re: oil bath air cleaner

I replaced an aftermarket chrome air filter on my 23rd series with the original deluxe oil bath air filter that I found in the trunk. It took a day of washing over and over to remove the rats nest that was built by the dirty rats inside the can. After sanding, painting, and making the proper stud and wing nut I proudly put it on the car. Not only does it look proper but it dramatically silenced the intake roar from the engine. That big can crossing the engine is really a muffler with internal baffles.

The oil bath air cleaner does a good job in cleaning the air because it works by centrifugal force flinging the dust particles into the oil as the air turns the corner. I suspect the reason the oil bath air cleaners became obsolete is a higher cost of manufacturing plus extra profit for the parts department selling replacement dry filters.
