GoGreen70MC Posted September 28, 2022 Share Posted September 28, 2022 I opened up the air cleaner today and noticed there was a filter made of a brillo pad like material inside the air cleaner where the vent tube from the valve cover connects. Does anyone know what this piece is called? Mine looks pretty grimmy and thought I should probably try to replace it. Thanks in advance.

Dtret Posted September 28, 2022 Share Posted September 28, 2022 Just pop it off and take it with you. Any auto parts store should have it. I always called it the air cleaner vent filter or pcv filter in air cleaner. It worked for me. They are only ( well used to be) just a couple bucks. 4 Quote Link to comment Share on other sites More sharing options...
jft69z Posted September 28, 2022 Share Posted September 28, 2022 PCV crankcase breather filter. I used to clean them with carb cleaner years ago if they weren't too bad, but that one looks a little well worn. AC Delco FB59 will do what you need. Cross that number to any other brand if you want. https://www.amazon.com/ACDelco-FB59-Professional-Crankcase-Breather/dp/B000C9SKFQ 1 Quote Link to comment Share on other sites More sharing options...
Andy's Auto Posted September 29, 2022 Share Posted September 29, 2022 It is used to filter the air that gets pulled in by the PCV valve on the opposite valve cover. Quote Link to comment Share on other sites More sharing options...

LJ72 Posted August 21, 2023 Share Posted August 21, 2023 I am curious to know if this tube can be removed and replaced with a filter cap insert on the valve cover? Quote Link to comment Share on other sites More sharing options...
