Disadvantages of the Daewoo X20SED engine
- The unit has a minimum of claims, its main problems are leaks and floating engine speeds;
- The reason for unstable idling is the contamination of the idle speed controller or crankcase ventilation;
- The exhaust manifold has low reliability, often it simply bursts;
- The weak point in the electrical part is the camshaft position sensor;
- The timing belt resource is about 60 thousand kilometers, and when it breaks, the valves always bend.
