V8 engines, such as the one in the BMW 750Li and ALPINA B7, are prone to oil leaks due to aging gaskets or seals.

These engines may develop coolant leaks from the water pump or radiator, leading to overheating issues.

The ignition coils in these models can fail, causing misfires and rough engine performance.

Clogged or failing fuel injectors can result in poor fuel economy and sluggish acceleration.

Issues with the timing chain or its tensioner can lead to engine noise and potentially severe engine damage.

Direct injection engines like these can suffer from carbon buildup on intake valves, affecting performance and fuel efficiency.

The ALPINA B7's turbochargers can experience failures or leaks, leading to reduced power and efficiency.

BMW engines, especially the V8 in the 750Li/ALPINA B7, are known for developing oil leaks from various seals and gaskets over time.

These engines are prone to valve stem seal issues, which can cause excessive oil consumption and smoke from the exhaust.

The N63 engine in these models can suffer from timing chain wear and failure, leading to engine performance problems and potential severe engine damage.

The high-pressure fuel pump in these vehicles can fail, causing engine stalling, rough idling, and difficulty starting.

The twin-turbo setup on the ALPINA B7 and 750Li can experience turbocharger failure or wastegate issues, leading to reduced performance and increased emissions.

Coolant leaks from the water pump, thermostat, or other cooling system components are common and can lead to engine overheating.

Direct-injection engines like the N63 can suffer from carbon buildup on the intake valves, leading to reduced performance and fuel efficiency.

Electrical issues can cause the battery to drain unexpectedly, which is a common problem in these models.

These engines can experience ignition coil failures, causing misfires and reduced engine performance.

Due to the complexity of the V8 engine, oil leaks can occur from various seals and gaskets, such as the valve cover gaskets or oil pan gaskets.

The BMW V8 engines, especially in the 750Li, are known for timing chain guide failures, which can lead to significant engine damage if not addressed.

The 2014 BMW 750Li and ALPINA B7 can experience coolant leaks from components like the water pump, radiator, and hoses.

Over time, the fuel injectors can become clogged or fail, leading to rough idling, misfires, and poor engine performance.

In the ALPINA B7, the turbochargers can fail due to high heat and stress, leading to reduced engine performance and possible engine damage.

Direct injection engines, such as those in the 750Li and ALPINA B7, can suffer from carbon build-up on the intake valves, reducing performance and efficiency.

The HPFP can fail, leading to starting issues, rough idling, and stalling.

Vacuum leaks from hoses and connections can cause rough idling, poor acceleration, and engine performance issues.

Problems with the electronic throttle body can lead to poor throttle response and reduced engine performance.

Various sensors (e.g., oxygen sensors, mass airflow sensors) can fail, leading to check engine lights and reduced performance.

BMWs, particularly those with V8 engines, are known for developing oil leaks from the valve cover gaskets and oil pan gaskets. This can result in oil dripping onto the exhaust system, causing a burning smell and potential fire hazard.

The N63 engine, which is used in the 750Li, has been known to have issues with the timing chain. Over time, the chain can stretch, leading to poor engine performance and potential engine damage if not addressed.

The cooling systems in these models can develop leaks, particularly from the water pump, thermostat, and radiator. This can lead to overheating and potential engine damage.

The high-pressure fuel injectors can fail, leading to rough idling, misfires, and reduced performance. This is a common issue in the direct injection systems used in these engines.

Both the 750Li and ALPINA B7 use turbocharged engines, and turbochargers can fail due to oil starvation, bearing failure, or wastegate issues. This can lead to loss of power and increased exhaust emissions.

Direct injection engines are prone to carbon buildup on the intake valves over time, which can lead to reduced engine performance, rough idling, and increased fuel consumption.

BMWs are known for their complex electrical systems, which can develop issues over time, such as faulty sensors, failing alternators, and battery drain problems.

Vacuum leaks can occur in various parts of the intake system, leading to erratic idling, poor fuel economy, and check engine light illumination.

The variable valve timing system (Vanos) in BMW engines can fail, leading to poor engine performance, rough idling, and increased emissions.
