What's the click of the Fox idle throttle? It was found after minor maintenance, which was obvious in the car. Some people say that it is the sound of the valve closing, but it is also true.

Hello, your noise may be abnormal noise caused by the valve or the engine timing chain. You need to check whether the oil pressure is normal first. If it is normal, you need to disassemble the engine to measure whether the valve clearance is too large and whether the chain tensioner is in good condition! I'm glad to answer your question. I hope I can help you. Have a nice trip! If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
