Installing a catch can next week have a few questions please.
 

Ok i completely understand what the catch can does and how to install it properly but i was wondering if anyone ever tied in the valve cover pcv/breather line and routed it down near the catch can and then with a "T" fitting connect it to the crank case hose that runs to the catch can?? i was thinking it would work just fine and eliminate the spoiled oily air being pumped back into our intake from the valve cover pcv. This way the crankcase and valve cover pcv are both pumping into the catch can and not back into our engine, and they should be ok connected together because both the valve cover and crank case breathers have one way valves on them to prevent them from back feeding into each other so they will both always be forced to run threw the catch can. If there is something wrong with what im saying please feel free to correct me, thanks

Also i have one more question about using a catch can on our car. How would there not be a vacuum leak while the intake manifold is in a vacuum state? reason i ask is because the inline pcv valve that is installed on the intake manifold side of the catch can hose will be wide open sucking in expelled air from the crank case pcv and the valve cover pcv because they will both be in the open position as well because of the positive crank and valve cover pressure. yes it will be filtered threw the OCC but will still be a vacuum leak. Right??? if im wrong or dont understand please help me. thanks in advance , i just wana make sure it is installed correctly the first time, you know what i mean???LOL Thanks!!

"Ok i completely understand what the catch can does"
"How would there not be a vacuum leak while the intake manifold is in a vacuum state?"

FAIL.

OK then how is it on a ms3 stock pcv system that even with the one oem hose that goes from the intake manifold to the crank case vent pcv, that at idle it would just suck the crankcase gasses right out kinda like a vacuum leak on the intake manifold right? am i missing something? is there some type of other restrictor or valve that keeps the motor from dying when its constantly sucking crank case air at idle? please explain i found nothing using the search, just right ups and how to's, but they never got technical enough to answer my question/ anyone?

also i just found out by searching the subject that the better catch cans have a mesh type baffle inside them to keep the sludge from splashing back up into the intake hose during hard driving with vacuum conditions. Does anyone know what this baffle/metal mesh or foam like stuff is made out of so that i could buy some in case my OCC kit doesn't come with one. Thanks tried searching and found nothing BLAH!!!

Whats the best material to use for a baffle under hard driving conditions so that the OCC wont splash sludge up into your intake tube????? I heard steel wool might work???? please advise THANKS

yes steel wool will work. just buy a fucking saikou michi catch can and call it a day. $85

aaron just installed on the VC. just look two posts away from this

hey dude hope this helps in addtion hit up aaron he has 2 catch cans installed I think.

I have two... one between the crankcase/pcv valve and intake manifold. the other between the valvecover and intake (post MAF).

JimmyMac's thread is very good...it's what I used to help iwth me my install. And here are my 2 threads:

Ive got a good question!! how does the positive crank case and VC pressure get released during boost if the pcv hoses going to the catch can are completely blocked off due to the boost pressure closing the valve on the intake side of the OCC???? seems like the pressure would be trapped until you let off the throttle and thats not good, right?? i know that the lines from the crank case and VC going to the OCC will be wide open durring boost but they are hooked up to air tight sealed OCC with no flow at all untill u let off the gas. i thought you wanted to get rid of Crank case pressure during WOT runs not keep it inside????? can someone help explain please? thanks

haha! Penis wrinkle is my buddy you guys be cool to him. me and him met back when I was doing curbs I knocked on his door to paint his curb when he had his suby and we talked for like 30min and then we met again at a speed meet. he is a cool niga yo!
