no i dont think removing the pcv is that great of an idea....since it helps relieve pressure in the crank case under WOT...at least thats what im told...mechanics...lol

Hey Andrew,

How long did this process take you?
As you know... I'm no stranger to pulling **** off my car for no reason just to see if it will still work without it... but what does SAI and EGR stand for? I know the EGR is that clusterfukc of crap on top of the head that makes it so impossible to make the 225 look neat.

Did this cause you to throw any codes?

it will take about an hour to do it all...the hardest part was getting the SAI pump out without removig the impossible to remove bracket...the N249 is the solenoid near the dipstick under that black cover infront of intake manifold...that stuff is the clutster f&ck over the three coilpacks...also the EGR is exhaust gas recirculation...bascially now the car wont recycle the exhaust gases its gets in and gets the hell out...that wasnt easy to remove cuz those damn allen head bolts stripped on me and i had to drill them out...make sure u have the 1.8t block off plate from 20squared to replace the egr....and i have no idea if im gonna throw a code or not....i havnt started it up in forever...i just did my timing belt because it was two teeth off and the new one i just did is now two teeth off....have no idea how the hell that happend but ya big waste of time cuz i gotta do it again....its complete BS the belt didnt jump or anything...i guess it wasnt a wate of time cuz i had a fairly new waterpump in there and guess what it was plastic!!and yes it was broken..so at least i got a metal one in there now....

If you dont have a resistor for both the sai and n249, you will throw a cel soon enough

SAI = secondary air injection
EGR = Exhaust gas recirculator

Both work to warm up your engine/cats faster, and burn any excess fuel vapors you might be dumping to atmostphere.
