This automotive maintenance tutorial was specifically written to assist owners of the first generation (2012, 2013, 2014, 2015, 2016 and 2017) Hyundai Veloster in checking or changing the PCV (positive crankcase ventilation) valve for the Gamma GDI 1.6 liter inline four cylinder engine.

Owners of other Hyundai or Kia vehicles such as the Elantra, Sonata, Azera, Santa Fe, Tucson, Accent, Ioniq, Genesis, Tiburon, ix20, i20, i30, i40, Veracruz, Optima, Cadenza, K900, Soul, Niro, Sportage, Sorento, Sedona, Rio, Forte and Spectra may also find these DIY instructions to be helpful.

A few compatible replacement PCV valves with their part numbers are as follows: Hyundai 26740-32804, Fram FV266, Standard Motor Products V231, Beck Arnley 045-0286, Luber-finer PC203, PTC PCV266 and ACDelco CV930C.

The tools needed to complete this procedure include a pair of pliers, a small flathead screwdriver and a 14mm wrench.

Pointing To PCV Location

Metal Hose Clamp
The first two steps are to open the hood and then pull off the plastic engine cover.

The plastic cover is held in place by four friction fasteners attached to metal pegs on the top of the engine.

Set the engine cover aside in a safe place.

The PCV valve is located at the front right (driver side) corner of the engine.

I'm pointing to the PCV valve location in Picture # 5.

If you have access to compressed air or a wet/dry shop vacuum, I recommend thoroughly cleaning off the area around the PCV valve to prevent from having debris enter the engine.

Pull Off Rubber Cover
Use a pair of pliers to squeeze together the two metal tabs on the hose clamp to release the tension.

While pinching the two tabs together, slide the metal hose clamp down and off the nipple on the right side of the old PCV valve.

Slide the outer foam rubber cover on the PCV vacuum hose off to the right.

Loosen Counterclockwise
Pull the rubber hose off the end of the old PCV valve.

If you have trouble removing the hose, use a small flathead screwdriver to gently pry it off.

Try to avoid damaging or piercing the PCV vacuum hose with the screwdriver.

Loosen the old PCV valve by turning it counterclockwise.

(Rotate the wrench towards yourself and the front of the car to loosen it.)

PCV Valve Housing
Spin out the old PCV valve the rest of the way by hand.

Inspect the old PCV valve by vigorously shaking it.

If the old valve doesn't make a rattle noise when shaken, it should be replaced.

I recommend buying the genuine OEM Hyundai 26740-32804 PCV valve.

If the old valve makes a healthy sounding rattling noise, it is probably still good and can be re-installed.

Carefully spin in the new PCV valve a few turns by hand in the clockwise direction to help prevent it from becoming cross threaded.

Push On Rubber Hose
Tighten the new PCV valve by turning it clockwise (towards the windshield) with the 14mm wrench until it is snug.

There will still be a few threads visible on the new PCV valve when it is properly tightened. You do not need to continue tightening the new valve until all the threads are hidden.

Do not over tighten the new PCV valve to prevent from having it break or damage the engine block.

Firmly push the rubber hose over the nipple on the new valve.

Line up the four rubber friction fasteners on the underside of the plastic engine cover with their corresponding metal pegs on the top of the motor.

Push the plastic engine cover back down in to place to secure the fasteners.

Start the engine and listen for any strange sounds that might indicate a problem.

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