Installation

Breather Hole Removal:

1. Position the Valve Cover topside down on a surface that will not scratch or mar the finish of the Valve Cover.

2. Make a center-punch mark in the Breather Hole you will be removing. (Some Moroso Valve Covers already have this mark). Use a hole saw to drill a 1-3/16" hole through the Valve Cover.

3. Use a round file to increase the hole diameter to approximately 1.22" and to remove any flashing.
