I welded AN fittings to my valve covers that will hook up to my MM race style catch can (no pcv). Some people have welded a baffle of some sort underneath but I had a different thought and wanted to know what you think. I was thinking about drilling multiple 1/8 or smaller holes where the bung is to act like a baffle. Do you think that would work or choke the system versus drilling it out to the full - 10 size and welding a baffle in? Thanks in advance.

i like the baffle idea rather than the restrictor. why not call MM and ask him what his system prefers?

Fuel cell foam works great as a filter media. Flows well, drains, and keeps the oil mist manageable. Also cheap and holds well.

Just carefully drill it and don't go through the factory baffle.

the GM performance valve covers don't have baffles built into them.

Well I finished my MM catch can tonight. I ended up drilling a 1/4 hole in the middle of the an fitting and multiple smaller holes around the perimeter. If I end up with too much oil in the can I'll weld a plate on the bottom.
