Owner's of other Honda or Acura vehicles such as the Odyssey, Insight, Ridgeline, CR-V, Fit, Civic, CR-Z, Crosstour, Accord, MDX, RDX, RLX, TL, TSX and ILX may also find these DIY instructions to be helpful.

A few compatible replacement PCV valves with their part numbers are as follows: Standard Motor Products V384 PCV, Wells PCV374, OES W0133-1709800-OES and Purolator PV1070.

The tools needed to complete this procedure include a flathead screwdriver, a 10mm socket and a 1/4" drive ratchet.

Rotate the two plastic fasteners 1/4 turn counterclockwise to unlock them.

Gently pull off the plastic engine cover and set it aside in a safe place.

The PCV valve is located at the front right corner of the 3.5L V6 engine on the passenger side of the vehicle.

It is near the oil filler cap and by the electrical fuse box.

Once the bolt has been loosened, spin it out the rest of the way by hand to prevent from having fall down in to the engine bay.

Set the bolt aside in a safe place.

Inspect the old PCV valve and shake it vigorously. If the valve still makes a healthy sounding rattle sound when you shake it, it can most likely be used again. You may also choose to clean it with carburetor cleaner spray or Sea Foam engine cleaner.

Since it is such a cheap part, I'd recommend purchasing a new PCV valve.

I recommend buying the Standard Motor Products V384 PCV since it has excellent reviews on Amazon.

Spin in the 10mm bolt a few turns in the clockwise direction by hand to prevent it from becoming cross threaded.

Try to avoid over tightening the 10mm bolt to prevent from cracking the plastic mounting loop.

Double check that the bolt is secure before moving on to the next steps.

Rotate the two engine cover fasteners 1/4 turn clockwise to secure them.

Be sure to record the PCV valve change in your Pilot's service records.
