Holley Valley Cover with Trussed Design and Oil Fill

Introducing Holley's latest addition to our extensive range of LS engine dress-up products: the LS valley cover with integrated oil fill provisions! Crafted from high-quality billet aluminum, these covers showcase a sleek, modern trussed design that not only enhances the look of your engine but also adds a touch of customization that stands out.

Each valley cover is thoughtfully machined smooth on the underside, allowing you to eliminate Displacement-On-Demand (DOD) features while providing a generous gasket sealing surface. Plus, if you need to reinstall the oil pressure sensor, we've got you covered with provisions for that too!

Whether you're working on an LS1/LS6 (10 bolt) or LS2/LS3/LS7/LSX (11 bolt) engine, each cover is custom machined to fit perfectly. To make your installation a breeze, Holley and Mr. Gasket offer all the necessary gaskets and upgraded hardware options separately. You can also choose from three stunning finishes: natural billet (clear anodized for protection), polished billet, and sleek black anodized billet.

Notes:

• If you plan to use the factory oil pressure sensor on LS2/LS3/LS7/LSX engines, please remember to carefully drill and tap the oil pressure sensor provision using the pre-located pilot hole on the bottom of the valley cover. You will need to drill and tap it to accept an M16 x 1.5 male NPT fitting.
• *For DOD Delete applications, ensure you drill and tap all 8 oil port holes to 1/8-NPT and install plugs in the oil ports to prevent loss of oil pressure.
