Engine construction

Hello, I have a 2013 1.2 VTI gasoline vehicle with 155,000 km on it. It used to be chronically losing oil, but now it's burning oil, producing white smoke from the exhaust and a burning oil smell. Has anyone had their engine serviced or opened? If so, in which city and by whom? Are you satisfied?

There is Uludağ Automotive in Bursa, you can go and meet with them if you want.

I wonder if Bursa Uludağ Automotive understands this. Have you had it done or had it looked at?
