Problems:
Oil leaks
Common in older BMW engines, often due to worn gaskets and seals.
Cooling system issues
Radiators, water pumps, and thermostats are known to fail, causing overheating.
Timing chain wear
Over time, the timing chain can stretch or the tensioner can fail, leading to poor engine performance.
Vanos problems
The variable valve timing system (VANOS) can suffer from oil leaks or mechanical failure, causing rough idling and reduced power.
Fuel injector issues
Clogged or failing fuel injectors can lead to poor fuel economy and misfires.
Mass air flow (maf) sensor failure
A faulty MAF sensor can cause poor engine performance and fuel efficiency.
Crankshaft position sensor failure
This sensor can fail, leading to starting issues and stalling.
Vacuum leaks
Cracked or damaged vacuum hoses can cause rough idling and poor acceleration.
Spark plug and ignition coil problems
Worn spark plugs or failing ignition coils can cause misfires and reduced engine performance.
BMW 735i 1988
The 1988 BMW 735i is a classic 7-Series sedan powered by a robust 3.4-liter, 6-cylinder engine producing 182 horsepower.

Problems:
Oil leaks
Older BMW engines, such as the one in the 1988 735i, are prone to oil leaks, particularly from the valve cover gasket and oil pan gasket.
Cooling system failures
The cooling system components, including the radiator, water pump, and thermostat, can fail and cause the engine to overheat.
Vacuum leaks
The intake manifold and various vacuum hoses can develop leaks, leading to poor engine performance and erratic idling.
Fuel injector issues
Fuel injectors can become clogged or fail over time, leading to reduced engine performance and fuel efficiency.
Timing chain wear
The timing chain and related components can wear out, causing noisy operation and potentially leading to engine timing issues.
Ignition system problems
Components like the spark plugs, ignition coils, and distributor can wear out or fail, causing misfires and rough running.
Head gasket failure
Overheating or prolonged engine stress can lead to head gasket failure, which can cause coolant leaks, oil contamination, and engine misfires.
Mass air flow (maf) sensor issues
The MAF sensor can become dirty or fail, leading to incorrect air-fuel mixture and poor engine performance.
