The variable valve timing system changes the timing of the intake and exhaust valves. Normally, the camshaft gear drives the camshaft. This ensures the correct valve timing, which is important for the operation of the engine. The variable valve timing system can adjust this timing. This allows the system to open or close the valves earlier. This allows the car to run more economically or faster. This allows the car to be adapted to the driver's driving preference.
Variable valve timing system and gear fault
After some time, the variable valve timing system and gear can become defective. It is then wise to replace the system on time. This is because the system and gear ensure the correct timing of the valves. If these parts are defective, the engine will not get the right amount of air. This has negative consequences for engine performance. You can recognise a defective variable valve timing system or gear by the following symptoms:
- The Check Engine light comes on: this light indicates that something is wrong with the engine system.
- Reduced or increased fuel consumption: this is because the valves open and close at the wrong time. The engine performance and fuel consumption are negatively affected by this.
- Rough engine: because the valves are not opening or closing at the right time, this causes the engine to run erratically.
- Rattling or knocking sound: if the camshaft gear is not fitted correctly, the teeth will not run smoothly.
Replacing the variable valve timing system and gear
You can replace the variable valve timing system and gear yourself, provided you have some technical knowledge. This is because various parts such as the timing belt or chain, the camshaft and camshaft bearings need to be disassembled. Would you rather have the camshaft gear and system replaced by a garage? Order the new parts cheaply at Winparts and take them to the garage yourself. At the garage the parts are often a bit more expensive. In addition, there are costs for the assembly. By ordering and supplying the parts yourself, you are usually cheaper off.
