BMW engines from this era, particularly the M20 engines found in the 325/325eS, are known for developing oil leaks from the valve cover gaskets, oil pan gaskets, and rear main seals.

The cooling systems in older BMWs can be prone to failure due to aging plastic components, such as the radiator, thermostat housing, and water pump, leading to potential overheating problems.

The M20 engine uses a timing belt, which should be replaced at regular intervals (every 60,000 miles). Failure to do so can result in the belt snapping, which can cause severe engine damage.

The rubber vacuum hoses and intake boot can become brittle and crack over time, leading to vacuum leaks that can cause rough idle, poor performance, and stalling.

Issues with the fuel pump, fuel filter, or fuel injectors can lead to poor engine performance, stalling, and difficulty starting.

Aging wiring and electrical connectors can lead to various issues, including intermittent electrical faults and sensor malfunctions.

The engine mounts can wear out over time, causing excessive engine movement, vibrations, and knocking noises.

The exhaust system, including the manifold and exhaust pipes, can rust and develop leaks, leading to increased noise and potential exhaust fumes entering the cabin.

The camshaft lobes can wear over time, particularly if oil changes have not been performed regularly, leading to reduced engine performance and efficiency.

The idle control valve can become dirty or fail, causing erratic idle speeds and stalling.

Older BMW engines, especially from the 1980s, are known for developing oil leaks from areas like the valve cover gasket, oil pan gasket, and rear main seal.

The cooling systems in older BMW models can be prone to failures, including issues with the radiator, water pump, and thermostat, leading to overheating problems.

The rubber hoses and gaskets in the intake system can deteriorate over time, causing vacuum leaks that can lead to rough idling and poor engine performance.

Depending on whether this model uses a timing belt or chain, either can wear out or become misaligned over time, which can cause severe engine damage if not addressed.

Fuel injectors can become clogged or fail, leading to poor fuel delivery, misfires, and reduced engine performance.

Older BMWs can have issues with ignition components such as the distributor, spark plugs, and ignition coils, which can cause starting problems and misfires.

Over time, the head gasket can fail, leading to coolant leaks, oil contamination, and significant engine damage if not repaired.

Engine mounts can wear out, causing excessive engine movement, vibrations, and even damage to other components.

The 1987 BMW 528e's engine is known for developing oil leaks, particularly around the valve cover gasket and oil pan gasket.

Older BMW engines, including the one in the 528e, can be prone to overheating due to failing water pumps, clogged radiators, or faulty thermostats.

The timing belt in the 1987 BMW 528e needs regular maintenance. If it breaks or is not properly tensioned, it can cause severe engine damage.

The engine may develop vacuum leaks over time, leading to rough idling, poor fuel economy, and reduced performance.

Issues such as clogged fuel injectors or failing fuel pumps can result in poor engine performance and starting difficulties.

A faulty idle control valve can cause erratic idling and stalling in the 1987 BMW 528e.

The engine's electrical system, including sensors and the ignition system, can develop issues over time, affecting engine performance and reliability.

The exhaust manifold on the 528e can develop cracks, leading to exhaust leaks and reduced engine efficiency.
