I'm getting myself confused once again. I had a friend over today and we were going over everything before I start my engine up for break in. It's a 383 SBC that I have built up from scratch.

We started wondering how the case is vented and I don't think it is, I overlooked this during the build. My valve covers have a hole that I put in a push-in style PCV valve (that I actually was thinking was a vent as well), and the other side has a push in oil cap. So do I need to drill in another hole and add in some sort of vent, I actually have a new one I had forgotten about.

Thanks,
Sean

I want to start this up soon!!!!!!!!!
