How to get PCV to work instead of valve cover breather!



Just to make sure, i have a gen V with L32 LIM and L67 throttle body. I do not have EVAP or EGR. Also i'm not intercooled.
Is it fine to run a hose from the back of the pcv nipple on the back of the supercharger to the nipple sticking out in the front that use to be used for the EVAP????

No, must drill and tap L67 TB. Connect hose from back of gen 5 to drilled and taped hole in L67 TB.
 
Look for the brass plug on the bottom of the l67 TB as in the first post. It's very simple , but at same time , can seem confusing.
 
Think of it like this..

PCV must be between throttle plate and MAF sensor.
EVAP is after maf and after throttle plate.
 


I looked last night.

It is the air intake for the IAC. From in front of the Throttle plate and behind the maf. Then the IAC allows this air to bypass the TB plate.

Reason behind my asking is 67Goat used that instead of the lower plug to tap pcv in. It'll work from what I can see. Only thing I'd be leary of is that PCV oil is going to coat the IAC, which usually gets dirty enough on it's own.
 
Ok guys here's where I'm at,gen v blower with a stg2 ic for a gen 3 with The lim and ic modified for pcv function by Zzp. I will be using a n* tb by The way.

My question is how do I use pcv function with this setup? I have no evap and or egr.
 
You are putting a N* on a gen 3. The Intercooler isn't an issue because you have the groove and drilled core from ZZP. You need an adapter plate to bolt the N* up. I'm not sure how the adapter plates work in this case. Who's adapter plate do you have? What do they say about pcv?

No sir,I'm going to be using a gen v blower on my modified lim for The gen 3 Stg 2 ic,The n* will be on The gen v. Will my gen v blower pcv fuction be ok using The gen 3 lim and ic?

Yes, PCV will work with tiny groove LIM. The gen 5 will work with the gen 3 LIM. Connect nipple on the back of gen 5 to nipple on N* to get PCV to work.

You are a god among men. I have never had an answer answered before i was even able to type my question.

Thank you kind sir.
 


i get it but there are too many combinations of throttle bodies and intercoolers and superchargers so what do i have to do if im intercooling my L32 with a L32 throttle body and Gen V where the pcv already connects in between the throttle plate and MAF?
 
Typically you'd end up with a turn down, making any factory PCV there useless.

The issue here is the PCV between the LIM and the blower is interrupted.

You will need to bypass this by having a hose go from your valve cover of the head with blocked PCV to a port before the TB blade, yet after the MAF.

Install a fitting in your intake and call it a day.
