Problems:

Oil leaks
Older Mercedes-Benz engines, particularly those from the early '90s, are prone to oil leaks due to worn gaskets and seals.
Head gasket failure
The inline-6 engines of this era may suffer from head gasket failures, leading to coolant and oil mixing or loss of compression.
Timing chain stretch
Over time, the timing chain can stretch, leading to poor engine performance and the potential for serious engine damage if not addressed.
Fuel injector issues
Fuel injectors can become clogged or fail, causing poor engine performance and reduced efficiency.
Vacuum leaks
Aging vacuum hoses and gaskets can lead to leaks, affecting engine performance and causing rough idling or stalling.
Overheating
Cooling system components, such as the water pump, radiator, and thermostat, can fail with age, leading to overheating issues.
Worn valve seals
Valve seals can wear out, leading to increased oil consumption and smoke from the exhaust.
Sensor failures
Older electronic sensors (such as the oxygen sensor) can fail, leading to incorrect fuel-air mixture and poor engine performance.
Egr valve problems
The EGR (Exhaust Gas Recirculation) valve can become clogged or fail, causing increased emissions and reduced engine efficiency.
