Has anybody done this? I have an HO valve cover with PCB valve in it. I was wondering if anybody has done this so i can hook the PCV valve to intake vacuum to draw crank case pressure out instead of it pushing itself out.

 

HO didn't have a PCB or PCV valve. Only CCV fittings kinda like a REnix.

 

If I remember right, my 1991 yj had a pcv valve. That's the only reason I was asking if anyone had done this

 

No PCV on a 4.0.....

 

I fit a 99 valve cover on my 89 head rear line goes into intake, forward hole has an elbow and a filter

 

And no PCV............

 

Okay. Thank you for the correction cruiser. I trust your knowledge. I guess what I was meaning to ask is there any way to get the front intake port tied into some sort of vacuum?

 

Actually the rear port is the vacuum and the front port is the filtered air coming in from the air filter assembly.

 

Until you hit throttle the suction from throttle body draws crankcase pressure out under no/low vacuum situation thru front of valve cover.

 

Nope,l literally just a little elbow and a small parts store filter stuck on it since I don't have the stock air box

 

So this elbow is what pulls air in from the air box?

 

The front one, yes.

 

Okay, so the previous owner must have been stupid, cuz that big hose in this picture leads to. Right to the front elbow

 

Why not just keep the Renix cover and replace the hoses?
