Intake Camshaft Timing Sprocket Gear

This precision timing gear is a key part of the engine valve timing system ⚙️. It is needed to keep the intake camshaft synchronized with the crankshaft, so the intake valves open at the correct moment. Correct timing helps your engine start smoothly, idle stable, and deliver proper power and fuel economy.

How it works

The sprocket mounts on the intake camshaft and is driven by the timing chain. Its machined teeth hold steady chain engagement while the camshaft turns. On many modern Nissan/Infiniti engines, accurate sprocket indexing also supports variable valve timing control, keeping response sharp across low and high RPM ✅.

What happens if it fails

If the gear teeth wear, crack, or the sprocket slips, timing can drift. Symptoms often include rattling near the timing cover, misfires, loss of power, rough idle, poor fuel mileage, and check-engine lights. In severe cases, incorrect valve timing may allow piston-to-valve contact, causing major internal engine damage ?.
