Default PCV Valve REPLACED Idle Problem GONE!!

Hey all, just thought id share my experience with you guys.

Car has the usual on it,

VF30
FMIC
Catless turbo back
EM
Protune. yada yada

Anyways, I started having a MINOR idle issue, The car would shoulder every couple of seconds, not a big shutter, but my vaccum would lose a couple psi everytime it happened.

I started to replace all vacuum lines hoping for there to be a slight crack in one.

No Luck.

I was walking through napa autoparts today to buy some hoseclamps and stumbled across the PCV section, 3.49 cents later, i have a new PCV Valve ready to install.

Im bored, wifes gone for the weekend, so i said what the hay, lets work on the car.

Took off Turbo Charge Pipe, Took off stock BPV Recirculation fitting, pulled off the hose to pcv.

Now the cool part is, you can use a DEEP 3/4 Socket to get it off, yeah i know im supposed to use metric, but i didnt have one, but it worked great. Came off, went back in with no troubles.

Fired up the car, let it warm up, and BAM, idle issue gone. Car idles STRONG!!!


I know its not a fix for everyones problem, but my stock PCV was pretty gummed up, it might help some people on here with higher miles =)

For what its worth, ENJOY!!!

2) Replace PCV.
3) Replace intercooler.

yeah, in all honesty, its as easy as the above post. absolutly nothing to be scared about, an oil change is more labor intensive than pulling the pcv

A 3/4" socket is 19.05 mm, so not surprised it worked if the pcv is 19mm - another good one to remember is 7/8" which is 22.2mm (I had a 6-pt box wrench which I used for my rear transverse bushing - worked like a charm)
