Fabricated Valve Cover Question

[FJ5]

I am considering buying some fabricated valve covers, and was noticing there is no filler hole or vent on the covers. Just wondering what some of you have done to address this situation.

Drill your own.Use aftermarket rubber bungs for the fill and breathers. most autoparts stores will have what you need. The new step type drill bits work pretty slick for this.

Just check the diameter number of the hole that the rubber grommet that comes with the breather is designed to fit and cut the hole.

Make sure you put one in each cover, so the crankcase can cycle properly, or even better if you set it up with a PCV. It will blow oil everywhere with one.
