Catch can vent to atmosphere

[MOFiST]

CFM actually called me and asked it I wanted a Race Red vice the powdered red, lol. I was like sure

So I'm curious are you running a catch can as well? Can't see your sig on my phone.

looks good JPGC...Keep us posted as to how this works out...

Now that you have the CFM installed did you remove the breather tube from crankcase to intake and cap both sides?

I am also running a Moroso catch can.

I left the tubes alone as I have a catch can installed as well.

OIC...But the OCC you have is for the PCV line...

I thought the primary purpose / benefit of installing a breather cap was to eliminate the breather line which recirculates vented hot air back into the intake?

Not necessarily, just to vent excess pressure and hopefully reduce blowby through the PCV further. I'm going to run both for now and see how much I'm catching in the catch can. Before the breather, I have been catching about 1/2 an ounce every 1500 miles or so. We will see if that changes. Hopefully I don't get a gift of a messy engine bay due to this, lol. We will see.

Has either of you guys examined the breather tube going to the intake? I was told by a guy on another forum that his was bone dry.

I'm more concerned with oil making it back to the intake. Personally, I still want some positive crankcase ventilation, so I'm keeping the PCV lines. You will lose the positive ventilation if you remove the PCV and you will just be venting excess pressure.

The one on the driver's side of mine is dry, but the passenger side is a totally different ballgame.

Are you referring to the driver's side hose?

You might want to try a few WOT pulls and then remove the filter and see if there is any residue oil pooling on the top of the CFM baffles....I'm interested in this as it sounds promising but still somewhat skeptical given the number of complaints I've heard...

Please keep us posted!

yes..that's it...its the crankcase breather line that is recirculated back into the intake....supposedly the CFM eliminates the need for this...

I'm considering deleting that hose, lol. I miss understood you earlier. I'm going to drive a little with it connected to see how it is. I've got to figure a way to properly plug it if I decide to remove it.

Will definitely do!

thats a good idea to wait first and see how the CFM works out.......

If the CFM works out you can purchase the caps and clamps at any auto store....

Btw, the way that this is designed, it changes nothing under vacuum...only under boost and wot will it do anything to vent excess pressure.

yes I understand....the breather cap has a built-in check valve...a very novel / creative design approach!

Lol, I wasn't saying you didn't but for those who may read this that don't know. I didn't want you to take it that way.

sorry..I got caught up in the conversation....good stuff! I am very interested in this!
