Advance sound after engine warming up

My vehicle is citroen saxo 1.5 diesel. Since it is almost the same as the Peugeot 106, I wanted to express my problem under this title. It is now an old vehicle, so finding support can be a bit difficult.

Let me explain the problem as follows. About 2 months ago, my v-belt was broken. He broke the pulley and broke into the timing frame and disbanded the team. I had the car built by paying a high sum.

But ever since, there is an advance sound at low revs. The master made adjustments 3-4 times, but he does not hold. After the vehicle warms up for 10-15 minutes, the hop advance sound begins. No sound when cold or short distance after first start-up. Especially if the car is warmed up and uphill, it sounds incredible.

He opened up again today. "The advance sender is not holding the setting," he said. Is that possible? "We couldn't find the piece," he said. If anyone has an idea and can support, I would be very pleased. I wear it so much that I can no longer sleep.
