Valve sound in the vehicle

Hi friends. On my 206 1.4 hdi diesel 2003 car there is a voice that I could not solve for 1 month.
Let me start over. One month ago, when the car was thinking, there was a noise, it was kayistan or something, the next day the smell came, I stopped the car and left. I took it to the service with the hammer, the pulley fell to the scattered plastic trigger, and the tire of the trigerin broke the seal.
The car did not work there, adjusted the sentence. 1. At the end of the week, the voice of the valve started to sound. Then the voice went. After a while he came again. When he took some distance, he went again. It has been coming once every 5 days for 1 month.
I doubt the sound setting. Traction and turbo transition time is good. The car that runs very quiet in the turbo is heard in the turbo as soon as that noise is heard. What do you think I'm not trapped?

The problem may be that the sente setting and the eccentric gear are impaired.

Sente setting fine workmanship or good engine master is enough.

Thanks bro. The master said, so let's look at his synthesis.
