Disadvantages of the Mitsubishi 8A80 engine

  • The engine requires only quality 98 gasoline or the fuel system will fail;
  • The intake valves here quickly overgrow with soot and cease to close tightly;
  • After 100,000 km, catalysts fall apart, and the exhaust clogs with crumbs;
  • Carefully monitor the condition of the timing belt, as its breakage is fatal for the unit;
  • But the main problem of the engine is in short supply and the very high cost of spare parts.
