Keep intake-cam timing responding on command with the Standard Ignition Engine Variable Valve Timing (VVT) Sprocket VVT597, a direct-fit replacement for the intake (left) camshaft position on the listed applications: the 2001-2004 and 2006-2008 Subaru Outback, the 2006-2007 Subaru B9 Tribeca, and the 2008-2009 Subaru Legacy.
- Position: Cataloged for the intake (left) camshaft position.
- Variable cam timing: Uses engine oil pressure, directed by the VVT control solenoid, to advance and retard the intake camshaft toward the commanded valve timing.
- Direct-fit replacement: Designed to install on the listed applications.
The sprocket is the mechanical actuator the timing system rotates to shift intake-cam phasing across the rev range. Cam/VVT timing fault codes, a rattle at start-up, or rough running can be signs the sprocket may need replacing, but these symptoms can also come from the oil-control solenoid, low oil pressure, or worn timing components, so diagnose the cause before replacing. If a worn or stuck sprocket is the cause, VVT597 replaces it.
