Disadvantages of the HXDA engine
- Most of the problems for owners are caused by not very reliable phase regulators;
- In second place are frequent failures of the components of the ignition system and the fuel pump;
- Regular oil leaks from under the valve cover or crankshaft oil seals;
- Once every 100,000 km, a large maintenance is needed with valve clearance adjustment and timing replacement;
- After 200,000 km of run, you will most likely have to deal with the decarbonization of the motor.
Good day, is the HXDA and HXJA same engine?
