breather with one-way check valve
I have an open air element, so I plugged the vacuum line, kept the pcv valve, and put a breather on the passenger side valve cover.
I realize I should be using a breather having a one-way check valve, so as to allow gases to exit at higher pressure, but not allow atmospheric air to enter.
Anyone have any recommendations for one?
Thanks in advance

Re: breather with one-way check valve
You'd be so much better-off to remove the hot-air air cleaner, reinstall the OEM air cleaner and then assure that the air cleaner has a source of cold (ambient) air via the OEM ductwork. In winter, you could re-connect the Thermac system to prevent throttle-body icing, and in summer let the engine pull in ambient air.
Open-element air cleaners were obsolete in the '60s. Popular, but obsolete.
