The Edelbrock PCV valve (PCV #3593) provides crankcase ventilation by relieving pressure generated by higher-output engines. Specified for Pro-Flo EFI system use, this PCV helps manage crankcase pressure and ventilation in compatible EFI setups. Its role is to control blow-by gases and support proper crankcase ventilation for engines equipped with the appropriate Edelbrock EFI plumbing.
