So I have a vented can with two ports, and I want to use it along with the factory system that consists of rear driver side valve cover going to the top of intake, front pass side valve cover goes to the side of intake just behind the throttle body.
So I've read the concerns of "unmetered air" and stuff like that, I will be speed density of that makes a difference.
I know it can be as simple as capping ports on the intake and putting breathers in the valve covers, but I do want a funtioning pcv system.
So I'm thinking I can just leave the factory system in place with the addition of check valves so that during most of normal driving it will work as normal,
Then for boost , I was thinking I could drill and tap the valve covers and connect them to one port of the catch can, and the other to the turbo's air filter inlet??
If done like this (assuming this will work) is the vented can part not gonna let the turbo create enough vacuum to pull fumes?
Ok scratch everything I just said, I've decided just to cap the side and top of intake, put a breather on pass side valve cover, run a hose from driver side valve cover to the catch can port, then from the second port of catch can to the air filter. Done.
This should give ventilation in and out of boost, not smell and be the simplest.
Pretty sure I'll need to change to a sealed can, or is the turbo capable of "pulling"excessive amount of oil?? Can't imagine it could?
Mine goes from behind tb, to can, from can to dr side valve cover. Pass side breather in oil filler cap( you can buy one on eBay that screws in from hawks third gen) 35$
the hose to the main air filter really isn't doing much for you as it appears clean air will draw into the can filter over to the engine filter vs pulling only can fumes through
if you start pushing oil out the driver filter then run that hose to the can. if that is a truck valve cover it has a tiny hole in it, and to be functional as an exit fitting should be drilled out. this is your typical full time open venting race style setup, not pcv, not scavenging.
with your original plan as long as you are speed density there is no meter (maf) to worry about unmetered air, so that would have been fine.
if you wish to get back into a high hp/boost functional pcv or scavenging system feel free to pm me.
I looked at the Mighty Mouse stuff, talked to him, might switch over the winter.
For now I use the truck PCV and go to an oil sep, then to a ck valve(so I don't blow boost back in), then to vac. behind the throttle body-I orig used the LS6 PCV in the valley cover, but it sucked to much oil. The truck PCV gets some oil sucked thru it, hence the oil sep-i have a breather on the oil filler, seems to work decent-I know when I redid it, it thru the idle tune off on my Holley HP

Thanks for respone, I really was trying to get something done now lol, you know-how it is....
I may look into one go your systems as I believe I do want a functional pcv.
With that said, yes it is a truck valve cover, and I did notice that hole looked very small...
Could this be made to work better for the time being by sealing off can? That would allow for more vac from turbo ??

Yea I deff like his stuff, and for some reason I can't wrap my head around this stuff, so when it comes time to make proper, I'll let him handle it

you cannot do too much research, and of course an opinion you trust is valuable, but don't be afraid to ask WHY until satisfied.
