Holley 241-362 - Holley LS Valley Cover with Oil Fill - Black Billet

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. Gasket offers all the necessary gaskets and upgraded hardware options to complete your installation. The new LS valley covers with oil fill provisions are available in three unique finishes: natural billet (clear anodized for protection), polished billet, and black anodized billet.

If it is your intent to use the top mounted factory oil pressure sensor on LS2/LS3/LS7/LSX engines, you will need to carefully drill and tap the oil pressure sensor provision using the pre-located pilot hole on the bottom of the valley cover. The hole should be drilled and tapped to accept an M16 x 1.5 male NPT fitting.*If using for DOD Delete you must drill and tap all 8 oil port holes 1/8-NPT and install plugs in the oil ports or loss of oil pressure will occur.
