Got my crawford block ready to go in but dont know what to do with the vent on top of the block right behind the water pipe. My wrx block doesnt have it so should i cap it off or what do you do with it?

Come on noboby knows?

add an extra set of vents to your valve covers and te them to the extra vent in the block or just cap it off,

Thanks i was going to cap it off but wasnt sure if i was missing something.
