Standard Ignition V297 PCV Valve Overview

The Standard Ignition V297 is a plastic PCV valve built for crankcase ventilation service on select Lexus applications. It uses a push-on attachment with a straight nipple design, two hose connections, and compact inlet and outlet diameters for a direct-style replacement in the emission control system.

Compatible With 1990-1997 Lexus LS400, 1992-1997 Lexus SC400, and 1992 Lexus SC300, this PCV valve supports proper crankcase ventilation on the vehicles listed below. The V297 is a practical choice when replacing a worn or restricted valve on these Lexus models.

Detailed Description

Standard Ignition V297 is a PCV valve designed for vehicles in the crankcase ventilation system, where it helps route vapors through the engine’s emission control plumbing. Its push-on design, straight nipple orientation, and dual hose connections make it a direct-fit style service part for the specified Lexus LS400, SC400, and SC300 applications. If you are replacing a PCV valve on a 1990-1997 Lexus LS400 or a 1992-1997 Lexus SC400, the V297 provides the correct connection style and hose sizing for those applications. This part cross-references 2-9392 and PCV392 for the same application.

Common Reasons for Replacement

• Rough idle caused by restricted crankcase ventilation flow
• Oil vapor buildup in the intake system
• Excessive crankcase pressure
• Vacuum leak symptoms from a worn PCV valve connection
• Emission control service on a 1992 Lexus SC300, 1990-1997 Lexus LS400, or 1992-1997 Lexus SC400

Installation Notes and Tips

Verify hose condition before installation and confirm the 1/4 in. (7 mm) hose size matches the existing plumbing. Because this valve uses a push-on attachment and no connector or gasket is included, inspect the mating hoses and fittings for wear, cracking, or hardening before installation. Confirm the inlet and outlet orientation matches the original part before placing the valve into service.

Quality Assurance

Standard Ignition supplies replacement emission control components for service applications, and the V297 is built to match the listed fitment and connection style for the vehicles shown above.
