Problems:

Oil leaks
Older BMW engines, especially those from the mid-90s, are known for developing oil leaks from valve cover gaskets, oil pan gaskets, and rear main seals.
Cooling system failures
The cooling system components such as the radiator, water pump, and thermostat can fail, leading to overheating issues.
Vanos issues
The Variable Valve Timing system (VANOS) in these engines can malfunction, causing rough idling, loss of power, and poor fuel economy.
Cracked cylinder heads
The 6-cylinder engines in older BMWs are prone to developing cracks in the cylinder head, especially if the engine has overheated.
Timing chain wear
The timing chain and associated components can wear out over time, leading to rattling noises and potential engine damage if not addressed.
Vacuum leaks
Vacuum hoses and intake boots can deteriorate with age, causing rough idle, stalling, and poor performance.
Fuel pump failure
The electric fuel pump can fail, leading to issues with starting and running the engine.
Mass air flow sensor (maf) problems
The MAF sensor can get dirty or fail, causing issues with engine performance and fuel economy.
Ignition coil failure
The individual ignition coils can fail, resulting in misfires and rough running conditions.
Throttle position sensor (tps) issues
A faulty TPS can lead to erratic engine behavior and poor throttle response.
