ok i know this has been discussed to death, but i did a search and was unable to come up with an answer to my question. it is:
does the valve cover need to be connected to the intake for, as i would guess, air flow, or could i take two breather filters and bypass the intake all together, thus not letting unmetered air into the system?
to clarify, put a breather filter on both sides of the cam cover and then sealing off the intake, would it have any negitive effects other than the enviroment?

did you keep your pvc valve in place or did you remove it. im told idle will be smoother and throttle response will be improved.

kept it in, i think. dunno, just D/C the 2 hoses, capped them, and put breathers on. as far as throttle response goes, just to the throttle cable mod, search for it on the boards, its there. it helps just a little, nothing too noticable.

i had did that "mod" before it was posted up here as a mod. lol. when i bought the car it just seemed way too loose.

im looking through my chilton's manual right now trying to figure out how to bypass the egr system. i may buy a jdm ga16de real soon, and it wont have one anyway.

buy a t fitting, and a breather filter. cut the PCV valve tubing in half, leaving it connected to the intake manifold and the crank case. put the t-fitting in there, so that the PCV line is still connected, but there will be a T off of it. then install the breather filter onto the open end of the T fitting. not only will this allow you to pass inspection, but its a noted 3-5 HP gain at the wheels (and yes that is realistic) and improved throttle response/better gas mileage. in this way, the air still moves from the crankcase to the intake manifold, but unmetered air is also sucked in from the outside through the breather filter, instead of expired out into the atmosphere. the air coming in swirls into the existing air going into the intake manifold, and allows for better air/fuel mixture. it also allows the crankcase to breath easier, for HP gains. im sure you could also T a breather into the line going from the intake to the crankcase too, although i havent heard of anyone trying it yet, im sure that you cant go wrong doing it there as well. but T-fitting a breather on the PCV valve is definitely the way to go.
theres a company that markets a product, which is basically a T fitting and a breather filter, to put inline on the PCV valve line, so its not a bad thing, its been researched and developed
