Mercedes M119 engine
The Mercedes-Benz M119 engine is a V8 petrol engine that was introduced in 1989 to replace the M117 engine. The M119 engine has an aluminum and the same cylinder head, forged connecting rods, cast aluminum pistons, two camshafts for each cylinder bank (DOHC), chain drive and four valves per cylinder.

The M119 has hydromechanical valve timing, allowing phase adjustment up to 20 degrees:
- In the range from 0 to 2000 rpm, synchronization slows down to improve idle speed and cylinder purge;
- From 2000–4700 rpm, synchronization is increased to increase torque;
- Above 4700 rpm, synchronization slows down again to improve efficiency.
Initially, the M119 engine had a Bosch LH-Jetronic injection control system with a mass air flow sensor, two ignition coils and two distributors (one for each cylinder bank). Around 1995 (depending on the model) the distributors were replaced with coils, where each spark plug had its own wire from the coil, and the Bosch ME injector was also introduced.
For the M119 E50 engine, this change meant a change in the engine code from 119.970 to 119.980. For the M119 E42 engine, the code was changed from 119.971 to 119.981. The M119 engine was replaced by an engine M113 in 1997 year.

Problems M119
The chain resource is from 100 to 150 thousand km. When stretching it, extraneous sounds may appear, in the form of tapping, rustling, etc. It is better not to start it so that you do not have to change the accompanying components, for example, stars.
Also, extraneous sounds can come from hydraulic lifters, the reason for this is a lack of oil. It will be necessary to replace the oil supply connectors to the compensators.
M119 engine tuning
Tuning the stock M119 does not make sense, since it is expensive and the result in terms of power is minimal. It is better to consider a car with a more powerful engine (sometimes it is cheaper to buy such a car right away than to tune a naturally aspirated M119), for example, pay attention to how many opportunities there are for tuning М113.
