Hey everybody! I finally got a nice Jeep. Its another members car. Its a very nice 90 2rd. Its in a great shape but has a few little issue.

the whole PVC system is messed up.

here is a picture of whats going on.



I need to figure out how its all set up and what it should look like.

 

Its a CCV system not a PCV system.. There is no traditional PCV valve like you are looking for.

The only thing missing is a tube from the valve cover where the breather is at. The tube runs to the place on the right where all the vacuum lines go together. The 1/2 tube that comes from the airbox joins the one from the valve cover

 

I see. What's with the vacuum lines? On my 94, the hose from the valve cover just goes right to the intake. But that does not seem to be the same on the 90. Do you have a picture of how it should be all set up?

 

heres a pic it goes right to the back of the air box

 

So it comes out of the valve cover and goes right to the airbox? It really does not have to go thought that junktion where all the vacuum hoses are, right?

 

Do you have a picture of where it connects to the airbox?

 

Is the ccv system same as it is on 91-96?

 

Anybody?

 

That's wrong.....

The small rear line goes to the intake.. the front one goes to the airbox.

I will try and get a picture of my 90 for reference. I have a tube intake though so its slightly different.

 

yeah i know that the rear one goes to the intake. is there any online parts place with diagrams?

 

so any help at all?

 

I want to know why in the Rushin Picture, the pcv hose looks different than this diagram. My cherokee have an air suction in the same place or near pcv valve and i dont know where the line must go... .

 

it looks like everything is fine if u hook up the valve cover breather to the airbox
u have nothing to worry about

 

This just made me realize my PCV system is all screwed up (stupid PO stuff) I'm gonna snap a pic tomorrow and show you guys if I cant figure it out myself lol.

 

I've got the vac diagram but I can't post photos. Somebody PM me and I'll send it to you.
