I am looking for a nice original 1963 pcv valve to try in my car. After comparing the flow of the 590c at idle with a fixed orifice it seems the idle flow is equal to approx .100" which is quite a bit of air at idle.
I want to find a original pcv and try it to see if it's more restrictive. After looking at the Paragon repro valves, the pictures look OK but I am curious about the flow of the repro parts. I am not crazy about installing a .063 fixed orifice in the rubber hose because at lower vacuum WOT high load the flow will always be the same .063".
If there is anyone the has a nice original correct for my early 63 please email or send a private message. I have read the correct cv590 valve is approx. 2 5/16" overall length and the later valve is longer. I appreciate the help, Tim
