PCV Valve

I have a 2007 Accord V6 and i need to replace the PCV valve. Other than the valve itself, is there anything else that i need to purchase to do the job? Where is the PCV valve located on this model? Thanks in advance.

If you'd look closely at the pictures, you'll see that there are couple of o-rings on the shaft body of the valve. Overtime the valve gets clogged up, rubber o-rings harden up and the excessive pressure in the engine is not being ventilated properly through the PCV valve as it is clogged, so the oil particles that's being sloshed around the engine are being pushed through the hardened rubber o-ring seals onto the surface. Replace the valve.
I replaced mine from dealer bought online for roughly about 30 bucks plus shipping.
