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

[matt5112]

it doesnt have a provision for rear PCV?

Depending on what kind of IC core you have you either have a funcational rear and non functional front or you don't have either. If you don't have either you can run a front valve cover on the rear head and a catch can off the rear.

I didn't do my PCV research before I got or installed my IC so I have no idea what it has PCV wise, I'll just post pics. Right now I just have a breather on front valve cover and a breather on back SC nipple which idk if it even does anything.

LIM being used, bottom one

IC on motor

I have some more if these don't help.

Is the older WBS Intercooler drilled in the back for PCV? Do you have any pictures of the Intercooler?

 

[matt5112]

Yeah, it has rear PCV.

 

[footballplaya3k]

Matt, does that mean its working though? I'm pretty lost...

 

[sseilmnop]

If it has the back hole and the matching hole in the intake manifold then drilling the port on the L67 throttle body should work.

 

[footballplaya3k]

I feel pretty dumb but I don't even know what hole you're talking about lol. I posted my LIM, do you see the hole there? I have a few more IC pics if you need them...

 

[sseilmnop]

I started typing and missed the pictures of the WBS Intercooler. It looks like there current generation Intercooler and intake manifold.

So what does that mean? Lol

 

[sseilmnop]

See circled hole in blue.

 

[sseilmnop]

You have the rear PCV hole.

 

[footballplaya3k]

Awesome, thanks for that lol. So what needs to be done to the rear to make it work correctly?

 

[matt5112]

Nothing.

It should be working already.

But on a stock L32 the SC nipple connects to the TB between the butterfly and MAFS. My nipple just has a breather on it. Doesn't something need done?

 

[matt5112]

Well you can hook it up like an L32 and have metered air.

 

[sseilmnop]

Drill and tap TB just like the pictures show.

 

[footballplaya3k]

So should I tap the TB and then have a split line going off that to the front valve cover and to the back SC nipple?

 

[sseilmnop]

Put a cap on the nipple on back of supercharger, it doesn't go anywhere. Connect just like I show.
