Disadvantages of the Alfa Romeo 939A000 engine

  • The most well-known problem with this engine is the not-so-durable timing chain.
  • The resource greatly depends on the oil change interval and sometimes chains are changed at 50,000 km.
  • Like all units with direct injection, this one suffers from carbon deposits on the intake valves.
  • Keep the radiators clean, as overheating immediately breaks through the cylinder head gaskets.
  • Also, engines of the first years of production suffered from rapid destruction of the catalyst.
