CC TEST
A quick and easy method to get CC volume on piston valve reliefs, valve head dishes or anything else is to fill the area with clay. Drop the clay in a buret with a measured volume of fluid and see how much the fluid level goes up. I like to use windshield washer fluid as it dries quick and cleans up easily.
