Disadvantages of the IQDB engine
- The main problem of the engine is dragging catalyst crumbs into the combustion chamber;
- Next come the failures of the components of the ignition system, they do not like bad fuel;
- On specialized forums, they complain about leaks from under the valve cover or the rear crankshaft oil seal;
- Every 100 thousand km you need to adjust the valves, there are no hydraulic lifters here;
- A small resource here also has a gasoline pump and a belt of mounted units.
