Detailed Description
The Standard Ignition V594 PCV Valve regulates crankcase ventilation flow in supported Toyota engines by replacing a worn or restricted valve with a screw-in design. It is listed for 2018-2024 Toyota Camry, 2016-2023 Toyota Tacoma, 2016-2020 Toyota Sienna, and 2017-2019 Toyota Highlander, making it a direct-fit service part for those model years. This part cross-references Beck/Arnley 045-0439 and Gates EMH9018 for the same application.
With a 0.22 in. inlet diameter, 0.21 in. outlet diameter, and straight nipple layout, V594 is built for the specified hose and threaded connection points. The included O-ring helps support a proper seal during replacement on Toyota Camry, Tacoma, Sienna, and Highlander crankcase ventilation systems.
What It Helps Fix
- Excess crankcase pressure from a restricted PCV valve
- Rough idle caused by unstable ventilation flow
- Oil vapor buildup in the crankcase ventilation system
- Vacuum-related drivability issues tied to PCV wear
- Service replacement for a leaking or sticking PCV valve
Installation Notes and Tips
Verify the thread size, hose size, and valve orientation before installation. The V594 installs as a screw-in PCV valve and uses an included O-ring for sealing; no separate gasket, cap, or hose connector is provided. Confirm vehicle application by year, make, and model before service, especially on Toyota Camry, Tacoma, Sienna, and Highlander engines.
Quality Assurance
Standard Ignition supplies replacement emission control components for crankcase ventilation service. V594 is built to match the listed fitment and connection specifications for the supported Toyota applications.
