Hello and Merry Christmas everyone!

Can anyone tell me if the 94 Automatic 4X4 V6 has a PCV valve, and if so, where is it located? A link to a picture or diagram would be extremely helpful.

 

I wish I could tell you but, could someone tell me where the PCV valve is on my 3.0 4runner 1990? Also does it help any to replace it?

 

Should be on the passenger side valve cover, under the intake manifold that you need to pull that off to get to it but if you have very small hand and arm you don't have to remove the intake manifold to get into it.

 

They are both in the same place. Very hard to get to. On the passenger side on the valve cover under the plenum partially hidden by vacuum hoses. Use a flashlight.

 

If you're going to do the PCV valve/grommet/hose, you might considering pulling the plenum and doing the valve covers gaskets. Those tend to leak if they've never been replaced. It's not a difficult job, and there's plenty of us here that can walk you through it if you need the help.

 

sounds like a pita job glad i dont have my 3.0L anymore
