OVERVIEW
Black Market Race's Gen 1 B58 Billet PCV Cover replaces the failure-prone factory PCV diaphragm with a true billet cover, removing the diaphragm entirely for maximum crankcase ventilation. It seals with a dual O-ring design and is available with or without a Radium banjo fitting for -10AN plumbing.
SPECS
- Billet PCV cover for the Gen 1 B58 valve cover, -10 ORB outlet
- Dual O-ring seal
- Removes the factory PCV diaphragm for maximum ventilation
- Designed, tested, and manufactured in-house in the USA
- Included as standard equipment with Black Market Race's B58 Gen 1 Catch Can Kit
PARTS INCLUDED
- (1) billet Gen 1 B58 PCV cover
- Radium -10AN banjo fitting (when "Include Radium Banjo Fitting: Yes" is selected)
TECH RESOURCES
- Required – venting: run this cover into a catch can such as the B58 Gen 1 Catch Can Kit. If venting straight to atmosphere without a catch can, Black Market Race states an inline check valve on the 10AN hose is required (not included and not sold by Black Market Race or Speed Logic).
- Installation: no install PDF or official video is published for this part. Due to variance in valve covers, Black Market Race currently supplies a set-screw-mounted cover while a twist-lock version is in development.
- Fits Gen 1 B58 only (not Gen 2 B58 or S58).
