I think its on the passside of the engine towards the rear. Its kind of a thick hose located where all the other little hoses are. The pcv hose runs into the side of the intake manifold. All these V6s (engine called a 3VZ) have the PCV in the passenger side valve cover. It can't be seen easily as it's under the intake plenum.
smack in the middle of the valve cover
top of the valve cover front and center. there is two big vacuum hoses and the pcv is the forward most (front) one.
under intake manifold passengers side valve cover
Its on the passanger side valve cover under a clutter of little hoses near the firewall
I believe it is located on the passenger side valve cover. You will have to remove the air surge tank to access it.
4 cylinder does not have pcv valve.
back of the valve cover-passenger side i believe-it has a vacuum line running to the intake.
The PCV valve on a 1997 Toyota Avalon is located on top of the engine. It connects the left valve cover with the intake.
The PCV valve is usually on top of one of the valve covers.
The PCV valve is located on top of the valve cover in the middle.
pcv valves are always located on valve covers (but not all vehicles have pcv valves)
