I know this is an older thread, but I just added a factory PCV system that I found at a swap meet that came with all parts; rocker cover, PCV tube and valve, air filter, etc. In reading through tech tips I saw a tip on replacing the oil bath element. Liked the idea, thought it was a lot of work. So, started measuring and doing research. I found an air filter at summit racing that is 8 inches in diameter and 3 inches tall. I removed the factory oil bath guts and inserted this element. My clearances for air flow, height and everything else are nearly identical to the oil bath insert and I get better air flow. The summit filter is Summit Racingâ„¢ Reusable Air Filter Elements SUM-G3007
Part Number: SUM-G3007
I would post before and after pictures but can't get that to work. The appearance doesn't change.
