The Mercedes-Benz M119 is a V8 automobile petrol 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 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 4-valve aluminium unit with dual overhead camshafts
• The connecting rods are forged and enable cooling of the pistons with sprayed oil
• The pistons are iron-coated cast aluminium
• An improved vibration damper system is used
• The aluminium oil pan has bolted-on oil baffles to prevent foaming of the engine oil
• The intake camshaft timing is adjusted hydro-mechanically 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
