    PML Cadillac Valve Covers Installed on a Mercury

    Wes King has a 1950 Mercury with a Cadillac 500 engine. He did custom machining of the top of these PML Cadillac valve covers and then installed them on his Mercury. Looks great! Our thanks to Wes for sharing his pictures.

    Finishes

    These valve covers are available in the natural as–cast finish.

    The as–cast finish can be custom painted or powder coated by a local shop if desired.

    These valve covers are sand castings. So they have the texture of sand. This texture usually is visible through the powder coat or paint, similar to an orange peel look and feel.

    Read here for more information about finishes and construction of PML parts.

    Gaskets

    Cork or cork composite gaskets are recommended.

    PML designed a gasket for these valve covers. See Gaskets for PML Cadillac 368, 425, 472, 500 Valve Covers.

    PCV, Breather and Oil Fill Holes

    PCV, breather, and oil fill holes are optional. A billet oil cap is also available.

    PML designed these valve covers with locations that can be machined as needed. Holes can be machined on the top at the ends or on the intake manifold side.

    PML can machine holes to order. This carries an additional fee and is custom machining. Machining must be ordered over the phone.

    See this PDF file for more info. It shows pictures of PML Cadillac valve covers with PCV and breather holes and oil caps. File will open in a new tab or window. May take a minute.
