Holley LS Valley Covers with Oil Fill Provisions

Holley’s extensive lineup of LS engine dress-up products just got bigger with these valley covers with oil fill provisions. A perfect LS upgrade if you’re looking for a subtle, custom look, these billet aluminum covers feature a modern, trussed design with integrated oil fill neck and billet oil fill cap. Machined smooth on the underside to eliminate displacement-on-demand (DOD), Holley LS valley covers instead present an ample gasket sealing surface and provisions for reinstalling oil pressure sensors.

Custom machined for LS1/6 (10 bolt) or LS2/3/7/X (11 bolt) patterns and available in three finishes: Clear Anodized Natural Billet, Polished Billet, and Black Anodized Billet. All necessary gaskets and upgraded mounting hardware sold separately.
