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

Will do. Thanks for the help.

Added note to original post about l32 engines and throttle bodies.

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.

On an L67 Tb. The plug on top of the TB. Does that connect to the IAC?

Don't no, I never played with that part.

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.

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?

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 thought I understood this until I started reading all the post I guess ill just stick with a breather for now

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?

Anyone??

I believe you just run a nipple off your oil filler to the hole in the intake before the tb.
