Valve Cover Breathers

[Two Lane]

Are there "bigger/better" valve cover breathers than the common
"flat-topped round mesh filter sitting atop the billet fill-pipe"?

What other GM or aftermarket breathers fit the billet pipes?

("Looks" aren't important to me, as the priority is max. venting of crankcase.)

TIA!

Not really sure that you should care that much. I am pretty sure that any that the vendor's commonly sell are fine.

Isn't the main reason to go to these is to keep oil from being pulled into the trubo inlet on a stock system? If which ever you choose accomplishes that, then no biggie.

I am sure someone much (TR) wiser than me may have more to add.

MOROSO is selling some screw together pipe bits to fit the 1.2" valve cover holes, and then uses a screw on breather.

I'm going to JB Wled the Moroso parts together, and then use some Clamp-On K+Ns.

You are using a check valve in the PCV line, right?.

Thanks for the replies...

Yep, got a good Check Valve.

The Moroso pieces sound great...will look into them!

I have the Kirban's breathers. Work good for me.
