Right‑Hand Exhaust Camshaft Sprocket for Subaru ⚙️
Precision timing is the heart of your Subaru’s boxer engine. This RH exhaust cam sprocket (OE ref: 13321AA061) keeps the exhaust valves opening exactly when the ECU expects, securing smooth power, clean emissions, and quiet operation.
Why you need it
It synchronizes the crankshaft to the exhaust cam and provides variable valve timing (AVCS) on the right bank. Worn teeth or a sticking phaser throw timing off, causing noise, power loss, and codes.
How it works
The toothed gear is driven by the timing chain/belt, while an oil‑controlled phaser inside the hub advances/retards the exhaust cam. The ECU modulates an oil control valve, rotating a vane/rotor assembly a few degrees for torque, response, and economy. A trigger pattern on the hub feeds the cam sensor for exact positioning.
If it fails ⚠️
Expect rough idle, rattling on start, sluggish pull, poor MPG, and MIL with codes like P0024/P0021. Severe wear can let the chain skip, causing misfire, no‑start, or bent valves on interference engines. Oil leakage or metal debris are common signs.
Pro tips ✅
- Align all timing marks; lock cams.
- Torque center bolt to spec; use new seal/bolt if required.
- Clean oil and OCV screens are critical for AVCS health.
- Clear adaptations and verify cam timing with a scan tool.
