V6 PCV Valve Location - Toyota

Baba Booey · 02-08-2007, 11:41 AM

Does anyone know where the PCV valve is located on the 4.0L V6? I would like to replace it, but I haven't noticed where it is located. I'm guessing that I may need to remove the plastic cover over the engine to find it.

I think Toyota uses a term other than PCV valve. Does anyone know what they call it or have a part number? Thanks.

Oops! I meant to post this in the "Maintenance" section.

It's called a "ventilation valve":

Yours is an '06. Way too soon to even think about this. I plan on looking at mine and testing it at 96K km (60K mi) even though it's not even mentioned in any service schedule I've seen.

John,

Thanks for the great diagram. That makes it real easy.

Kmvreter,

I know you're right, but replacing the PCV valve periodically is one of those small maintenance items that a non-mechanically inclined person such as myself can do without much hassle. So for $10 or $15, I get to work under the hood and tell my wife that I'm going out to "work on the car."

I actually remove most PCV valves and then spray them brake-cleaner, on both sides. Once dry I try to blow thru the check valve in the wrong direction. If she leaks then I buy a new one. Also make sure the flow is possible in the correct direction.

John,
Where did you find the diagram, from a shop manual ?

I am wondering where to purchase a manitenance guide for my 03 4Runner ?

Yep. Got it on eBay. There are a number of other threads that discuss getting the manuals. Unfortunately, neither Haynes nor Chilton have one yet.

Am I right to guess the vent valve by the fire wall is the pcv valve?
