Optimize Engine Performance with Genuine PCV Replacement
Upgrade your vehicle with this precision-engineered PCV valve (part 26740-2G000 / 045-0404 / PCV490), designed to restore factory performance in 1.6L, 1.8L, 2.0L, 2.4L, and 3.3L engines. As a critical emissions control component, it actively manages crankcase pressure by recirculating unburned hydrocarbons into the combustion cycle.
Technical Excellence
Pressure Regulation: Spring-loaded diaphragm maintains optimal vacuum under varying RPMs
Thermal Stability: Withstands extreme temperatures without cracking or warping
Flow Accuracy: Precisely calibrated orifice controls gas recirculation volume
Direct Fitment: Matches OEM connector angles and thread pitch (M12x1.25)
Performance Benefits
Maintains Fuel Economy: Stable crankcase pressure optimizes combustion efficiency
Reduces Emissions: Ensures compliant hydrocarbon recirculation
Extends Engine Life: Mitigates sludge buildup and bearing wear
Installation & Maintenance
Locate the valve atop the engine valve cover (passenger side)
Pinch and disconnect the attached rubber vacuum hose
Rotate the old valve counterclockwise to remove
Insert new valve and rotate clockwise until snug (no overtightening)
Reconnect the vacuum hose firmly
Recommended replacement every 30,000 miles or during oil changes.
Why This Valve Stands Out
Unlike generic alternatives, this unit replicates OEM geometry down to the millimeter, ensuring zero clearance issues. The brass internal components resist corrosion from acidic vapors, while the nitrile diaphragm maintains flexibility in freezing conditions.
