  • In addition, the exhaust gasket constantly burns and the studs of its fastening break;
  • Often there is a bend in the valves in the engine due to a broken crankshaft shank;
  • The same thing will happen if the owner skips the timing belt replacement schedule;
  • After 100,000 km of run, the pump and the top radiator cap are often changed here.
