Ремонт 1ZZ-FE

In early March, I stopped at this service station, a car - Kaldina 241. Vibration annoyed me for two years, and the powerlessness of the diagnosticians was even more disappointing. Sentenced and pillows, and fuel, and gasoline in Russia is not the same, and that ZZ should shake. At a traffic light on a warmed-up engine, revs sank to 500, for 10 seconds the car shook and then revs rose to normal. The vvt-i valve worked only at 3000 rpm. I drove to this service station, met Eugene. He listened to the engine, picked up the laptop to the connector. And he gave out the alignment - traditionally, the first cylinder of the Khan’s coupling works at 3 thousand, because the oil pressure loss in the switchgear, in the valves, is in any way chaos. This I met in one sentence, Eugene it chewed me for 20 minutes. I say, why is the engine sausage? Eugene - yes, you have 8 points compression in the first cylinder, about 13 in others. And he himself didn’t even get a compressiometer. And he talked about the options kapitalok. I thought to myself that here, another diagnostician, divination on the fingers. He drove away from the service station, and thought that no one measured me with compression. I went on the way to the STO station, measured it - everything is as Eugene said, 8/13/13/13. The next day I called back, appointed a date kapitalki. I chose Kapitalka with a bore, replacing pistons and rings with repair ones, replacing a repair kit. Work with materials - 45 sp. I had a fresh timing kit, it did not change. As the capital was spent, Eugene threw off photocounts on Watsap. I liked that the entire engine was cleaned inside and out, the crankshaft was bored, the camshaft was polished, and the vvt-i coupling was polished. When he arrived to pick up the car, Eugene took out a valve adjustment log, which leads to the repaired engines, showed what kind of confusion I had in the valves. Such meticulousness I have not seen anywhere else. Eugene talked a lot about the work done, what for, what new and dead parts look like, I didn’t remember everything, but Eugene left the impression of a clear professional who sees 1ZZ through and through. In parting words, it was said not to spin the engine for more than 2000 revolutions over 2500 km, run-in, then call in to change the oil. Today I traveled only 1,500 km. Vibrations at the traffic lights have disappeared, the engine is working quietly, thrust has increased very noticeably, it is visible not only the compression in the first cylinder has risen, but the vvt-i clutch has worked as it should. I can’t say anything about gas mileage yet, I drove about 210 km on instruments at 15 liters, but then I will measure on a full tank. In short, I am pleased with the work done. The review is long, because there is a lot of time, self-isolation, her mother ...
