The variable valve timing (VVT) system alters the timing of the inlet and exhaust valves. Typically, the camshaft gear drives the camshaft, ensuring the correct valve timing crucial for engine operation. The VVT system, however, can adjust this timing, allowing the valves to open or close earlier or later. This enables the car to run more efficiently or deliver increased performance, tailoring it to the driver's preferences.
Variable Valve Timing (VVT) and Gear Failure
Over time, the VVT system and its gear can malfunction. It's advisable to replace the system promptly in such cases, as it's vital for maintaining correct valve timing. A faulty VVT system or gear can disrupt the engine's air intake, negatively impacting its performance. You can identify a faulty VVT system or gear by the following symptoms:
- The Check Engine light illuminates, indicating an issue with the engine system.
- Fuel consumption may increase or decrease due to the valves opening and closing at the wrong time, affecting engine performance and efficiency.
- The engine may run erratically because of the valves not opening or closing at the correct intervals.
- A knocking or rattling noise may occur if the camshaft gear is not properly installed, causing the teeth to misalign.
Replacing the Variable Valve Timing (VVT) System and Gear
You can replace the VVT system and gear yourself if you possess some technical knowledge. However, it requires disassembling various components, including the timing belt or chain, camshaft, and camshaft bearings. If you prefer a professional replacement, order the new parts affordably from Winparts and bring them to your mechanic. Parts tend to be more expensive at garages, with additional labour costs. Ordering and supplying the parts yourself can often save you money.
