WLFINKMO PCV Vent Hose for Chevrolet & Buick 2011-2020 - Direct-Fit Replacement with Bypass Valves, Oil-Resistant

WLFINKMO PCV positive crankcase ventilation hose is a direct-fit replacement pipe with bypass valves for select Chevrolet and Buick models (2011–2020) to restore correct crankcase ventilation and help stop oil leaks and rough idling.

This replacement PCV tubing fits factory routing on multiple GM compact models and is made from oil-resistant materials to tolerate engine bay conditions. It replaces part numbers 25193343, 55568267, and 46829 and installs by simply pressing into place—no special tools required. If your vehicle shows symptoms such as unstable idle, sluggish acceleration, or oil weeping from the valve cover area, refreshing the PCV pipe is one of the first maintenance steps to consider.

Which vehicles will this PCV ventilation hose fit?

This pipe is manufactured to match the original equipment geometry for several Chevrolet and Buick small cars and crossovers. Confirm compatibility by model year and engine layout before ordering.

• Chevrolet Cruze (2011–2015) and Cruze Limited (2016)
• Chevrolet Sonic (2012–2019)
• Chevrolet Trax (2013–2020)
• Buick Encore (2013–2019)

How does replacing the PCV pipe help engine performance?

Worn or clogged PCV pipes allow pressure and oil vapor to bypass or leak, which can upset air/fuel balance and deposit oil in intake passages. Installing a fresh, oil-resistant hose helps restore controlled crankcase ventilation and reduces related drivability symptoms.

• Promotes stable idle by restoring proper crankcase pressure control
• Prevents oil vapor from contaminating intake and throttle body
• Reduces chance of oil leaks at valve cover and crank seals

What are the key features and replacement part numbers?

The hose is manufactured to meet OEM routing and connects with the factory PCV valve and intake fittings. It’s a direct replacement for common GM service numbers and is built to withstand oil exposure in the engine bay.

• Replaces OEM part numbers: 25193343, 55568267, 46829
• Oil-resistant construction for long service life
• Includes integrated bypass valves where required by original design

How difficult is installation and what should I check afterward?

Installation is straightforward for a DIYer or mechanic: remove the old PCV pipe and press the new hose into the factory fittings until fully seated. After installation, run the engine and inspect for leaks or unusual noises.

• Tool-free fitment: press the hose into place with firm hand pressure
• Check for secure connections and no oil seepage after startup
• Verify improved idle stability and reduced crankcase blow-by symptoms

Who is this for: This WLFINKMO PCV positive crankcase ventilation hose is intended for owners and technicians of Chevrolet Cruze, Cruze Limited, Sonic, Trax, and Buick Encore (model years shown) who need a reliable, OEM-matching replacement to address oil leaks, unstable idling, or crankcase pressure issues.
