The PVC valve is located between the firewall and the top edge of the exhaust manifold and can be easily replaced with 6" needle nose plyers, a small tip flat head screw driver and a little patience.
Find the PCV valve and first step remove the black hose that runs from the valve to the manifold. On the side of the manifold t here is a vacum hose adjacent to the PCV hose that can be removed for better access. Once the PCV hose is removed you will note a cap with a 45 degree offset onto of the PCV valve. There is a clip (green) at the base of the cap that can be lifted to release it. Once this is off the PCV valve is exposed. The tricky part is to pry up or lift a small integrated tab that seats in a notch at the opening where the valve is seated in the block. Using a slot (i.e flat head) screwdriver lift the tab while turning the old PCV valve counter clockwise. It will pop out but you may want use the plyers to turn it.
The installation is reverse. You will see how it is seated, just ensure that the new valve is turned as far as possible clockwise until the tab is seated in the notch. You will feel it click into place. Then just reinsert the cap and hoses / clamps .
Took me 15 minutes without having to remove anything other than the two hoses attached to the manifold cover.
