PCV Valve location

Hi Guys,

Posting after a long time, I need to know the location of the PCV valve on my 2005 XLE LTD..........if some one can provide an image/diagram that would help. I have the PCV valve sitting in my garage for quite some time now and would like to know the location so I can change it out.

Thank You

Re: PCV Valve location

It's called a "ventilation valve" in the manual and so it took me a while to find it.

Re: PCV Valve location

I don't know that Toyota actually has a recommended replacement for the Sienna PCV. When I bought a replacement valve the parts guy gave me a funny look and said it was a "non-serviceable" part. That "n-s" pcv was pretty badly gummed up so I changed it out and now just clean it every 15,000 miles with a shot of carb cleaner.

Re: PCV Valve location

Gentlemen, is there one or two PCV valves in the 3.5 V6?
I see that in my 2012 Sienna they did an excellent job putting it in a very easily accessible place but i FEAR there is another on on the rear bank of cylinders that will be terrible to replace.
