Yeah, you really should have one. The PCV system is pivotal to oil health and it can't work right without one.

It doesn't have to be in the valve cover, though. You could drill and put one next to the distributor, or use a hose from the valve cover to a breather that's hidden somewhere.

I drilled one in the back of a cast valve cover once to keep things neat.
