Genuine Hyundai 26740-2G000 PCV Valve

Maintaining a properly functioning Positive Crankcase Ventilation (PCV) valve is crucial for optimal engine performance and longevity in your 2012 Hyundai Elantra. Here's a detailed explanation of the PCV valve's role, common signs of malfunction, and the benefits of using a genuine OEM replacement:The PCV Valve: A Vital Engine ComponentThe PCV valve plays a critical role in managing crankcase pressure within your Elantra's engine. It regulates the flow of crankcase gasses, primarily consisting of unburned fuel vapors and blow-by gasses (combustion byproducts that leak past the piston rings). These gasses are routed back into the intake manifold to be re-burned during combustion, promoting cleaner emissions and improved fuel efficiency.Signs of a Faulty PCV Valve:Increased Oil Consumption: A malfunctioning PCV valve can lead to excessive oil usage. This occurs when the valve sticks open, allowing unmetered air into the intake manifold. This disrupts the air-fuel mixture, causing the engine to run lean and burn more oil for compensation.Rough Idle and Jerky Engine Performance: A clogged or faulty PCV valve can disrupt the proper flow of crankcase gasses, leading to rough idling and hesitation during acceleration. This can be caused by a buildup of deposits within the valve or a failing diaphragm that struggles to regulate airflow.Check Engine Light Illumination: Modern vehicles often illuminate the check engine light (CEL) when they detect issues with the PCV system. This light serves as a warning to address the problem and prevent further complications.Smoke from the Exhaust Pipe: Blue or gray smoke emanating from the tailpipe can indicate excessive oil burning, potentially caused by a faulty PCV valve.Vacuum Leaks and Oil Leaks: A failing PCV valve or a worn-out o-ring can lead to vacuum leaks and oil leaks in the vicinity of the valve. These leaks can cause various performance issues and should be addressed promptly.Benefits of a Genuine OEM PCV Valve Replacement:Precise Fit and Function: Genuine OEM (Original Equipment Manufacturer) PCV valves are designed and manufactured to meet the exact specifications of your 2012 Hyundai Elantra. This ensures a perfect fit and optimal performance within your engine's PCV system.Reliable Operation and Durability: OEM parts are renowned for their superior quality and use of high-grade materials. This translates to reliable operation and extended service life compared to aftermarket alternatives.Easy Installation: Replacing the PCV valve in your Elantra is a relatively straightforward process that can typically be completed in under three minutes with a wrench and a 21 mm deep 6-point socket.Preventative Maintenance and Regular Inspection:Consulting your Elantra's owner's manual is crucial to determine the recommended replacement intervals for the PCV valve. Generally, it's advisable to inspect the valve every 10,000 miles and replace it around 30,000 miles to maintain optimal engine performance and fuel efficiency. By proactively addressing a failing PCV valve, you can avoid potential engine damage and costly repairs down the road.

Great fit for my 18 Hyundai Tucson. Seems to be good quality and a great value for my money.

Works as intended. Easy installation. Will buy again as needed.

My 2011 Sonata 2.4 has been consuming about a quart every 5-700 miles. As a part of trying everything to stop it, this was one of the first things on the list. At about 85K the original PVC valve still did rattle, but replaced anyway. Everything runs just as before, zero drop in oil consumption. So if you are buying this even though your original valve still seems good in order to try to curb oil consumption, dont.But it was a solidly built perfect OEM fit.

Good

Good part

Work perfect 2018 hyundai elantra and cheap also oem and the car rides better now

Why did you pick this product vs others?:Worked like it should and did mine at 100k miles which is where they aren't as effective in preventing oil burning.
