Need help!!
Here is my set up. I connected the front breather and pcv together through a T and then goes to the catch can because I only have a single catch can and I want to catch the oil from both pcv and the valve cover breather.
I tried to see if there is any other people do this but I couldn't find any.
Is this a good idea or not?

 

It looks a little.....

But it'll work. Make sure that can never fills up. Or the engine will be inhaling large amounts liquid oil.

I would not plumb the second port back to the intake. I would put a breather filter on the catch can and cap off the inlet on the intake tube. Again...make sure it never gets full.

 

Thanks for your advice.
But what do you mean "looks a little"?
And what's the advatage of putting a breather filter on the catch can compared to letting it vent without a filter

 

The front breather tube is for when you WOT, the other one is for general purpose crank case ventilation. That's why you put a breather on the front tube and run the other one on the catch can. Mixing them both as you're doing with your T, will do funky things with your crank case pressure.

 

It looks a bit rough. But presentation may not be important to you. It will work as-is. Kind of.

The purpose of open-venting a catch can is so that oil slosh cannot be sucked back into the intake.

Cap off the breather at the intake pipe. Put a breather filter on the catch can.

Do not put a breather filter on the valve cover. Leave that line so it runs into the catch can.

A 3-port can will work better.

One port for pcv. The other for the breather. The third placed on TOP for a venting/breather filter.

 

I think I'll just vent the PCV to engine bay and connect the front breather to catch can and from catch can to intake.
Feels like I should've bought a duel catch can

 

Ok.

 

I'd make sure that new tubing is oil resistant--- it may not be---if its not, the oil and oil vapor will dissolve it from the inside out into a gooey mess over time.

Any auto parts store will have rolls of black tubing of different diameters behind the counter that is oil resistant. They sell it by the foot. Would be a better choice once you finalize how you want the tubing to run---it'd match the existing tubing and last as long as the OEM stuff.

 

On my car, I've found I get 98% of the oil collected in my dual catch cans from the can going between the PCV and intake manifold. So in your case, I'd just connected the front breather to you K&N intake, and plumb the catch can to go only between the PCV and intake manifold.

 

Why not just go: pcv to catch, catch to throttle body.

Your setup looks over engineered.

I use a mini fuel filter between the pcv and TB. Change when it gets yucky and take 5 seconds
