sound help from the valve?

When I first start my car, my friends start working with a slight sound like a stylish chic from the engine. After 5-5 km, when the car warms up, this noise stops. But before the engine was cold, there was no such sound. or is there any other situation that is abnormal? I'm pretty obsessed, I would be glad if you can help with this.

I think it may be a sound coming from the balls, I think it is an uninterrupted sound from the valves ...

If the buses come in the first place and then recover, the oil may be related to the pump, as it cannot fill the thrusters properly.

Diesel filter and oil maintenance is every ten thousand or 1 year. it depends on your meticulousness. you are 11 thousand diodes. What makes it normal stylish stylish. the oil may have lost its properties.

How did you understand that the place where the sound was sounding?

You can be right about this. I had the last 69.000 würth engine and injector cleaning, now the vehicle is at 89.000 :).

My friend had this kind of voice in the scenic, but it was obviously disturbing. They said he was due to the valve when he made the car so he came to my mind in the first place :)

Greetings Is there any improvement?
