2.) if you run a staged computer with a aftermarket wg and bov you can get rid of all the lines running to the stock solnoids and just tuck them down in the whole behind the headlight...but be careful and make sure to keep the solnoids connected to the wires just not the vac lines because they will throw codes with out the wires connected

really cleansup that side of the engine bay...polishing the a/c lines is aso a plus to make it all clean...and all you relly need is a can of mothers polish and a buffer wheel on a drill and abut 30 minutes....looks awesome

I'm not sure if you responded the the wrong thread or what but your shits hooked up all wrong.

The correct way to have a catch can is
PCV valve to--> catch can --> catch can to--> throttle body. If you have a PCV check valve it needs to go between the throttle body and catch can so as to prevent the catch can from ever beeing pressurised by boost, (they aint designed to do that) The breather element on drivers side of the valve cover is optional but must be able to breath in and out, weather its hooked to the stock air box foam element or an after market breather.

PCV stands for positive crank case ventillation, what part of your breather is providing the positive part of that equasion? You have a catch can hooked up to the drivers side of the valve cover?? That needs a breather but there is no need for a catch can, it shouldn't have anything to catch if you had the PCV system connected correctly. If it is collecting oil currently than thats your motors rings not sealing and you have blow by.

Lemme break it down for you.

Vacume from the intake pulls blow by vapors from the valve cover via the PCV system, hence why you end up with oil in the upper pipe, the motor is constantly pulling vapors from under the valve cover to the intake. There is a active vacume in the valve cover all the time unless your under boost. To solve this vacume from sucking oil to the throttle body, and ultimately in to the combustion chamber, you install a catch can that allows the oil to settle out before it reaches the throttle body.

The breather on the drivers side of the valve cover is just that, a breather so there is never a true vacume created in the valve cover and it equalises pressure and vacume in the valve cover. If you are getting oil out of the drivers side off the valve cove that means your PCV valve is leaking boost in to the valve cover and you sould invest in a PCV check valve, or in your case, there is blow by pressurising the valve cover and blowing oil out where the breather should be.

im not trying to crap on this thread.....i was replying to some one asking about it....and yes i know that is the way everyone else has theres done....but even with a check valve and a catch can there is plenty of oil that passes by into the intake mani itself....when you run a breather off the pass side it vents the motor there...then when you run the drivers side-cc-intake what that does is under full throttle it pulls the un needed gas out the valve cover and puts it back into the turbo itself and burns it again...it still works like the factory designed except for instead of pulling all that oil and everything out when you at idle it pulls it out when you full throttle....look at old muscle cars thats the way they run alot of there systems and sometimes they use the exhaust itself to pull it out instead of the intake....its a better way of doing it....there is a like 50 page tread on here somewhere about it where phubarr440 describes the reason runing it that way will work better....the only reason it is run that way from the factory is for emissions purposes....i know everyone runs it your way...but this is just something diffrent and show me someone else on stock turbo that holds 18 at redline with no boost leaks with just a ported turbo non clipped and an apg wg...not trying to crap on this thread just reply to someones question
