Engine repair, replacement of oil seals, and rings - Toyota Will VS, 1.8 L, 2010

I'm tired of adding oil all the time, especially since another trip to the south is planned in the summer. I bought original rings, and an Auto-Veltovsky set of oil seals and gaskets. When parsing it, it was scary to look at the engine - everything inside was just covered with silt, what kind of bastard was driving a mineral water, I don’t understand, it’s not clear how the oil generally circulated through the engine, the oil scraper rings lay flush with the piston, there was a deposit of burnt oil on the pistons and valves in 1 - 2 mm. The compression rings are worn by about 0.3 mm. The wear is uniform on the cylinders, there is no stepped wear at TDC, the hon is not disturbed, the uniform wear over the entire plane is pleasing.
