RH Exhaust Camshaft Sprocket for Subaru Engines ⚙️
This right‑hand exhaust cam sprocket keeps your Subaru’s valve timing precise. It links the timing belt/chain to the exhaust camshaft and works with AVCS (variable valve timing) to advance or retard the cam for clean idle, stronger mid‑range torque, and lower emissions. Built to OE spec, it holds timing accuracy under heat and oil pressure, mile after mile.
Why you need it ️
Correct cam timing is critical. A worn or sticking sprocket throws off exhaust valve events, causing rough running, loss of power, and higher fuel use. Replacing a tired unit restores crisp response and protects the engine from timing errors.
How it works
Oil pressure, commanded by the OCV, fills chambers inside the sprocket. The internal rotor then shifts the cam angle relative to the drive gear. The ECU continuously adjusts this to match load and RPM, keeping combustion efficient.
If it fails ⚠️
- Rattle on start, rough idle, stalling
- Low power, flat spots, poor MPG
- Check Engine Light: cam/crank correlation or VVT codes
- Misfires and increased emissions; long‑term chain/belt stress
