Design and Benefits

PML valve covers reproduce the traditional style and shape of the stock valve covers with added height for many roller rocker system. PML sand cast aluminum construction adds thick walls and gasket flanges so there is not any distortion when bolts are tightened.

PML Valve Covers, hole location

The classic CADILLAC script is cast into the cover and raised. The script replicates the 1949 GM CADILLAC logo. These PML valve covers are licensed GM products. On powder coated parts, the powder coat is shaved off the top of the script.

These PML valve covers are baffled on the inside. If needed, PML offers optional machining for PCV and breather holes where the cover is baffled. The bottom of the photo shows the inside of the valve cover.

These covers feature a mid-height design that will clear most roller rockers. These valve covers were designed using a stock head and the Jesel Roller rocker system. Please check dimensions in above link to verify clearance for your particular configuration and see our web page on fitting PML valve covers on small block Chevy engines for examples.

These PML valve covers are standard perimeter mount covers for 1960 to 1986 small block Chevy engines (265, 283, 327, 350, 400). The bolt holes are straight across from each other (not offset or staggered).

This part replaces part number 8357-3, a small block valve cover with CADILLAC script and squared off corners.

Optional PCV, Breather, and Oil Fill Holes

Please read this PDF document on oil fill, breather and PCV set-up (click to view) for pictures and details.

PML small block valve covers are made without holes for PCV, oil fill or breather. The two most common engine configurations are (1) no holes required or (2) two holes required, one hole for PCV and one hole for a breather. Note that either of those holes can also be used for oil fill. We can also machine one hole in one cover (please call for this option).

For engines that require PCV and breather holes on the valve cover, PML designed the casting to be thicker on the intake manifold side below the C where an internal baffle is located. This area can machined with a hole. This way, the top of the valve cover is left alone for a clean, classy appearance.

Image shows valve covers with holes machined, PCV grommet, push-in breather, and mounting bolts.

To order the configuration with PCV and breather holes, choose the option in the shopping cart. The option for PCV and breather holes includes one hole in each cover, a PCV grommet, a push-in breather, and an oil fill tube.

Please call to order if your engine configuration requires one hole or to discuss your requirements.

PML machines the valve covers to order in our shop. We use four or five different tools on a CNC machine to create a neat, leak-free hole for PCV, breather or oil fill. Spot facing provides a smooth sealing surface for grommets.

To learn more, we have two videos. Please watch this step-by-step video of PML machining a PCV hole. We also have a step-by-step video of PML machining a hole for our push-in breather.
