Problems:
Oil leaks
Older BMW engines, including the V12 in the 1992 850i, can develop oil leaks over time, particularly from valve cover gaskets and oil pan gaskets.
Cooling system issues
The cooling system components, such as the radiator, water pump, and hoses, can wear out and fail, causing overheating problems.
Timing chain tensioner failure
The timing chain tensioners in the V12 engines can wear out, leading to timing chain noise or, in severe cases, engine damage.
Electrical problems
Older BMWs are known for electrical issues, including problems with the wiring harness, sensors, and control modules.
Vacuum leaks
Vacuum hoses and intake manifold gaskets can deteriorate, leading to vacuum leaks that affect engine performance and idle stability.
Fuel injector problems
Fuel injectors can become clogged or fail, leading to rough running and poor fuel economy.
Ignition system issues
Components like spark plugs, ignition coils, and distributors can fail, causing misfires and poor engine performance.
Mass air flow sensor failure
The MAF sensor can fail or become dirty, leading to incorrect air-fuel mixture and performance issues.
Crankshaft position sensor failure
This sensor can fail, leading to starting issues and poor engine performance.
