Holley's Ls valley covers with oil fill provisions are the latest addition to our expansive lineup of Ls engine dress up products. Machined from billet aluminum and featuring a modern, trussed design with an integrated oil fill neck and billet oil fill cap, these Ls valley covers are the perfect upgrade for your Ls engine if you are looking for a subtly custom touch.

These valley covers are machined smooth on the underside, allowing for the elimination of Displacement-On-Demand (Dod), and instead features an ample gasket sealing surface and provisions for re-installing the oil pressure sensor if necessary. Each valley cover is custom machined for either LS1/LS6 (10 bolt) or LS2/LS3/LS7/Lsx (11 bolt) patterns and Holley / Mr.
