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.
