The Edelbrock Signature Series valve cover for Buick 3.8L and 4.1L V6 engines ('77 & later) pairs functional engineering with a chrome finish and stock-style breather baffles that help prevent oil from reaching the PCV valve. These covers accept emissions equipment, include rubber grommets for breather and PCV openings, and work with optional matching breathers sold separately to complete the installation.
