The Mercedes-Benz M119 was a V8 Automobile engine produced from 1989 through 1999. It was available in 4.2 L; 5.0 L; and 6.0 L displacements. It was a Double overhead cam design with 4 valves per cylinder and Variable valve timing on the Intake manifold side. It was replaced by the 3-valve M113 starting in 1997.

The M119 differed from the M117 in the following ways:

  • The engine block uses asbestos-free gaskets and has better oil flow
  • The cylinder head is now a Multi-valve aluminum unit with Dual overhead camshaft
  • The connecting rods are forged and enable cooling of the pistons with sprayed oil
  • The pistons are iron-coated cast aluminum
  • An improved vibration damper system is used
  • The aluminum oil pan has bolted-on oil baffles to prevent foaming of the engine oil
  • The intake camshaft timing is adjusted Hydraulic-Machine up to 20°:
    • 0–2000 rpm — retarded for improved idle and cylinder scavenging
    • 2000–4700 rpm — advanced for increased Torque
    • 4700– rpm — retarded for improved Volumetric efficiency

The 5.0 L (4973 cc) version produced 326 PS (322 hp/240 kW) at 5700 rpm and 354 ft·lbf (479 N·m) at 3900 rpm. Later engines had the full throttle enrichment removed and power was a little less, nearer 315 PS (311 hp/235 kW).

Applications:

The 5.0L M119 was also adapted for racing with the addition of two turbochargers. It won the 1989 24 Hours of Le Mans in the Sauber C9 and was further used in the Mercedes-Benz C11 before being replaced by the M291 3.5L Flat-12 in 1991.
