ModMan intake Oil filler / PCV port?

I think the breather might be integral to the intake in some fashion. There's a lot of stuff going on in the stock intakes when I was looking at the 5.7 car one I sold. I don't know that's there's a fresh air intake for a PCV system in any noticeable location, but that would be a question for a Chrysler engineer, lol.

I tried running my system with no PCV (bad idea) and it blew the oil pan gasket. Ran it with just PCV and no breather and it was really dumping what seemed to be a lot of oil on the air filter. Ran it as just an open breather that wasn't plumbed to the air cleaner and it just made a mess on the intake around it with a bunch of oil. Finally put in a fresh air filter on one port and PCV on the other and the air filter appears to be running cleaner after a few hundred miles, time will tell. It may have had to do with my old cracked oil pan as well.

As for drilling the rocker covers, they're pretty shallow covers (like dang near flat), so it would be a little harder to drill into the side/end. You can just pop a cover off whenever you want the change the oil though. Would be a faster way to pour it in and you wouldn't have to do it all that often. Plus they're O ring gaskets, so they can be reused pretty easy.
