here is the setup on my vortech kit

drilled the intake and bought a grommet and 90* ford PCV elbow that is straight through, ran one end to the can, then the other to the stock VC vent. the can is also baffled on the interior. I used some steel tube with holes in it to force the vented oil mist to the middle/bottom of the can (which is stuffed with steel wool for the oil to stick to) I also added a 1 way valve after the stock vent so if the intake manifold is drawing more vac then the s/c intake it will still be vented



keeping it vented on and off boost for the about $45 that I have into it, I think its a GREAT setup

 

yes those line do you have a pic on how to route it?

 

I'll likely run a filter on the breather port (my car is still in pieces):

 

Just got done installing my setup!

 

Clean

 

ok ok so Im doing a SC build and Im confused: why are some people only venting the catch can while others are plumbing it to the intake (before FI boost pressure, so there is only ever vaccume)???

If I understand correctly, you need to have a vent to atmosphere for WOT conditions AND a catch can plumbed to a vaccume source (like the intake) for suction under idle or light load conditions as the pressure in the crank case/valvle cover isnt enough to force out the blow-by fumes.... am I correct?

Plz advise on a cheap easy set up!

Thanks guys!

 

An ideal catch can/vent system will not recirculate back into the intake

 

Why is that? does the system not need vaccume from the intake to remove harmful gasses from the crankcase? I was under the assumption that the catch tank was to remove the oil vapors from the air that went into the intake???

thx for the advise

 

The system doesn't need vacuum. Recirculation (like the factory setup) is done for emissions purposes. Pressurized gases from the crankcase will evacuate without issue. It's really up to you, honestly. If you would prefer a closed system, go for it. The differences between an open/recirculated system will be negligible/marginal in most cases anyway (with regard to pressure evacuation).

 

ohhhh ok ok I gotcha! Vented it is then!

Thx bud!!
