Billet Valve Cover VS. Catch Can

**Chrisf90** · 06-29-2021

I'm looking to get rid of these oil drops in the garage, so I’m trying to figure out how this billet valve covers work.

The main CCV lines go down to my frame rail, but there are 2 other vents from the cam cover area link into the valve cover.

If I get a new billet cover with a 5.9L style baffled breather it solves the main line but where do those other 2 lines tie into or do I plug them.

My Breather filter is gutted.

Or any good recommendations for a catch can.

Thanks

So I just put one on mine.

I plugged one line and used the other one to plug the crankcase pressure sensor into.

So far, so good.

Also, you will still need a catch if you don't want oil going back into your intake.

My valve cover also has a baffling breather, but I have it routed to a Mishimoto high flow catch that can be mounted to the frame rail, and it still catches oil in it.

Mishimoto Universal High-Flow Baffled Catch Can Kit

A note about this kit is you will have to order the smaller hose barbs. The ones that it comes with are one inch and you need 3/4in if i remember rigjt

I’m running a beans machine billet valve cover with baffle and motion race works catch can mount on the frame.

I got a fleece fuel pump block off plate to get rid of the oil return y pipe but you can just plug the line before the y pipe.

Even with the baffled valve cover, you will get oil in the catch can.

You got any picture of how y’all mounted it to the frame?

I take it I would be back by a body mount cause there’s not much room around that side of the engine for me.

I was hoping a good baffle would keep a lot of the oil from coming down out of the tube.

Thanks
