This automotive maintenance tutorial was specifically written to assist owners of the second generation 2014, 2015, 2016 and the updated 2017 or 2018 model year Nissan Rogue SUV in checking or changing the PCV (positive crankcase ventilation) valve in the QR25DE 2.5 liter inline four cylinder engine.

Owners of other Nissan or Infiniti vehicles such as the Murano, Altima, Titan, Versa, Sentra, Maxima, Leaf, 370Z, GT-R, Juke, Pathfinder, Armada, Patrol, Skyline, Cube, X-Trail, Xterra, Qashqai, Rogue Sport, NV200, NV400, Teana, Q50, Q70, Q60, QX30, QX50, QX56, QX60, QX70 and QX80 may also find these DIY instructions to be helpful.

The compatible replacement PCV valve part number is genuine OEM Nissan 11810-1KC0A.

The tools needed to complete this procedure include a pair of pliers, a deep well 23mm socket and a 1/2" drive ratchet.

Release Hose Clamp
In order to easily access the PCV valve, you'll need to partially remove the part of the air intake assembly on the top of the engine.

Firmly pull the plastic peg on the left side of the air intake assembly out of the rubber grommet attached to the top of the engine.

Gently pull the rubber hose on the back side of the air intake out of the "C" shaped plastic retaining clip.

Then use a pair of pliers to squeeze the two tabs on the hose clamp on the rear of the air intake and slide it off the end of the hose.

Pull the hose off the air intake.

Loosen the old PCV valve by turning it counterclockwise with either a pair of pliers or a 23mm socket with a 1/2" drive ratchet.

Empty PCV Valve Socket
Once the old PCV valve is loose, spin it out the rest of the way by hand to prevent from having it fall down in to the engine bay.

Inspect Old Valve
2014-2018-Nissan-Rogue-PCV-Valve-Replacement-Guide-021
Test the condition of the old PCV valve by shaking it vigorously.

If you hear a healthy sounding rattle sound from the PCV valve, it is probably still good.

But since new PCV valves are so inexpensive, I recommend replacing it at least every other 2 to 3 years.

The genuine OEM replacement PCV valve part number is Nissan 11810-1KC0A.

Use 23mm Socket
Spin the new PCV valve in by hand a few turns in the clockwise direction.

Tighten the new valve in the clockwise direction to just past hand tight with a pair of pliers or the 23mm socket and a 1/2" drive ratchet.

Try to avoid over tightening the new valve to prevent from cracking it.
