This automotive maintenance tutorial was specifically written to assist owners of the first generation (2003, 2004, 2005, 2006, 2007 and 2008) Honda Pilot SUV in checking or changing the PCV (positive crankcase ventilation) valve located on the VTEC 3.5 liter V6 engine.

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

A few compatible replacement PCV valves with their part numbers include the following: Beck Arnley 045-0358, Airtex 6P1243, OES W0133-1709800-OES and Standard Motor Products V384.

The tools required to remove the old PCV valve and install the new one include a 10mm socket and a 1/4" drive ratchet.

Pull Out Old PCV Valve
The PCV valve is located on the front left (passenger) side of the engine.

It is situated just below the orange plastic oil level dipstick handle and to the left of the spark plug ignition coil.

Loosen the single bolt holding the PCV valve in place by turning it counterclockwise with a 10mm socket and a 1/4" drive ratchet.

Carefully spin out the 10mm bolt by hand to prevent from having it drop down in to the engine bay.

New Beck Arnley Valve
Set the 10mm bolt aside in a safe place.

Test the old PCV valve by shaking it vigorously. If the old valve makes a healthy sounding rattle sound, it should still be in usable condition.

Since new valves are so inexpensive, I recommend just changing it about every 30,000 to 60,000 miles for preventative maintenance.

I chose to buy the Beck Arnley 045-0358 PCV valve.

Slide In New Valve
Apply a small amount of new oil to the rubber o-rings on the new PCV valve.

Lubricating the rubber o-rings will help the new PCV valve form a better seal, prevent oil leaks and also make it easier to remove during the next replacement.

Clean the area around the PCV valve port (installation hole) in the engine. Make sure that the old rubber o-rings from the old valve are not stuck inside the port.

Slide the new PCV valve in to the port until it is flush with the engine.

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

Tighten the bolt in the clockwise direction with the 10mm socket and a 1/4" drive ratchet until it is snug.

Try to avoid over tightening the bolt to prevent from cracking the plastic mounting bracket on the new PCV valve.

Be sure to record the PCV valve replacement in your SUV's service records.
