PML Valve Covers

PML Valve Covers

PML valve covers feature strong cast aluminum construction and classic styling. Scripts are GM licensed for an authentic look. We design and manufacture our valve covers in the USA. Valve covers are available for many applications.

Finishes

PML valve covers are made using the sand-casting or die-casting process. These processes are the same processes that are used to make intake manifolds, water pumps, and engine blocks. PML's parts are not produced in huge quantities offshore and no two parts are exactly the same. Cast aluminum parts have a rougher surface finish than billet or stamped parts. When cast aluminum parts are polished, it is not uncommon for some porosity (very small holes) to be uncovered. To our customers this is a sign that these parts are unique and produced in small quantities.

Gaskets

For most PML valve covers, we recommend using stock gaskets available at an auto parts store. We do not sell gaskets or grommets. The exception to this is our LS1/LS6 finned valve covers, part number 10413. For this part, PML supplies a custom gasket of our design.
