Converting oilbath air filter to paper

08-05-2008, 01:04 PM
Hey I'm new here and really enjoy reading these. Can anyone tell me if there are any conversion kits (or if it is needed) to change the oilbath air filter to a paper air filter for a 66 beetle? Are there any problems with this idea?

Since the only "filtering" of the oil on VW engines is the screen in the sump, the oil bath air cleaner is the best way to keep dust and dirt from ruining your engine.

Paper air fliters aren't as effective as the oil bath. The Krauts in the White Coats (German Engineers) designed the oil bath air cleaner so they didn't have to put a standard oil filtration system in the engine. Who am I to question their wisdom?

The only reason they went to paper filters in the early '70s was to meet emission control regulations. Those filters were HUGE, compared to filters on similar sized engines on other makes. That was due to their trying to achieve comparable air filtration to the oil bath.

As long as you change the oil and clean out the bath at every engine oil change, you'll get many years dependable service from your '66.
