*Disclaimer* - I am not liable for anything you do to your car. This is just a basic walkthrough.
Also, you do not have to do it exactly how I do. Different people tackle things differently. This just how I do it.
Task: Change the PCV valve on a JX35/QX60
Time:45-60 minutes
Tools/Supplies Needed:
- Pliers
- 23MM DEEP socket (used to remove the PCV valve itself)
- 10mm deep socket (used to undo the various nuts in the removal process)
- A new PCV valve. I decided to go OEM and the part number is 11810-EA200.
- Depending on your socket sizes (3/8, etc.), a matching socket wrench
Process:
1) Open the hood to take stock in what we will be removing in the process of getting access to the PCV valve. We are removing: the air snorkle, the engine cover, a fuse/relay box and a protective cover that goes over the PSF reservoir.
2) Start by removing the four (4) 10mm bolts highlighted here for the engine cover and air snorkle:
3) Gently remove the air snorkle (should slide up and out relatively easily) and then loosen the following two (2) 10mm bolts holding the engine cover on:
4) Next, pop off this protective cover. There is two clips in the back and it should come loose with a light tug.
5) Moving on, lets remove this fuse/relay box and its mounting bracket in order to give our arms some extra room. The box comes off by pushing the two pins and sliding forwarding toward yourself. The bracket requires your deep 10mm socket. Be careful not to lose these nuts.
6) FINALLY! We're at the PCV. Look behind the intake manifold and you should see the PCV valve. Hopefully the hose clamp is pointing at you in such a way that is easy to get to with your pliers. Once you have a hold of the clamp, slide it up.
7) With the hose clamp moved up, you should now be able to wiggle the hose itself free with your hand. If not your hand, you may need to take your pliers and lightly twist it back and forth to get it free. Slide it up and out of the way as much as possible.
8) Now the fun part: removing the PCV valve itself. Take your deep 23mm socket and put it on the valve and then add your socket wrench. Hopefully you have enough power to loosen it a bit. Once you've loosened it with the socket wrench, I found it easier to remove the wrench and just use my hand to twist the socket itself and remove the PCV.

10) Installation is the reverse of removal. Take your time and you should be able to accomplish it.
