Fits Aftermarket Valve Covers with 1 5/16"-12 Screw-in Thread, Including Holley Cast LSx Covers
An Original Metco Motorsports Product!
This valve cover adapter replaces the original oil fill cap included with many popular aftermarket valve cover sets.
It is CNC-machined from billet aluminum for precise fit, and the included silicone O-ring is specially designed to prevent oil seepage at the base of the adapter.
The top of the adapter is machined to accept a #10AN hose end to facillitate the installation of a custom crank case evacuation system, PCV system, or for use with a vacuum pump.
Total adapter length is about 1.8", with about 1.25" above the flange of the cover.
Note: This adapter is also available with a filter on top under PN MBR0015, listed elsewhere in this section.
