Gasket burning

Hello friends, my car is likely to have a gasket. How much does it cost me?

Gasket burning had happened to me because I did not control the water of the vehicle. In 2017, I had it built at a price of 800 TL.

With the increase in the parts prices and workmanship on the ground, my brother is at least 1000 TL. just don't think of a seal. If the timing has not changed, it must be replaced with the parts that cause the circulation pump to burn the gasket, etc.
