Optional PCV, Breather, and Oil Fill Holes

PCV/breather/oil fill holes are optional. PML makes these valve covers without holes and can machine holes when needed for an engine configuration.

Our approach to PCV and breather holes is unique so we made a PDF file with pictures and details: https://yourcovers.com/Merchant5/graphics/00000001/valve-covers/11026_holes.pdf

If these PML valve covers are ordered with PCV, oil fill and breather holes, PML will machine one hole in each cover on the intake manifold side and include a PCV grommet, a push-in breather, and an oil fill tube.

Call if your engine configuration requires one hole or to discuss your requirements.
