Disadvantages of the KR20DDET engine
This turbo engine was manufactured not too long ago, and data on its malfunctions was gathered;
They frequently complain only about Start-Stop system bugs on specialized forums;
Deposits on the intake valves of the engine are removed by the combined injection system;
There are no hydraulic lifters, and the engine’s primary issue is where to fix the compression ratio system. The valve clearances must be adjusted every 100,000 kilometers.
