Disadvantages of the VG20 engine

  • If the engine runs rough, clean or replace faulty injectors;
  • Rarely, but there is a breakage of the crankshaft shank with a bend in the valves in the motor;
  • Closer to 200,000 km, hydraulic lifters are often knocking or a water pump is leaking;
  • Regularly it is necessary to change a burnt-out exhaust manifold gasket here;
  • It is very difficult to remove the release without breaking the studs, which are then not so easy to return.
