About Timing Chain Replacement

Hello everyone, I have a 1.6 vti vehicle, 139 thousand km, when will the timing chain change, how will I understand if it makes a sound or not. I made a phone call to a master, he said that even if that chain changes, after 20-40 thousand km or something, the vehicle will be made of the engine cylinder top cover (7 thousand TL). It was chronic. Thank goodness there is no problem in my vehicle. I'm waiting for your comments, thank you.

There is no such thing, my brother, if there is no problem in the operation of the shaking master engine, why opens the cover, compression test is done, but it is done to get the money of the nation. normally it says 180000 km in the change service booklet. It also costs between 1000-1500 TL, of course, it should be done by a place that knows the job.
