Oil leaks can occur from various parts of the engine such as the oil pan, valve cover gasket, or oil filter housing. This can lead to reduced engine performance and potential damage if not addressed.

Overheating can be caused by a variety of issues including coolant leaks, a malfunctioning thermostat, or a failing water pump. Overheating can cause serious engine damage if not promptly resolved.

Misfiring can be due to faulty spark plugs, ignition coils, or fuel injectors. This can result in poor engine performance, reduced fuel efficiency, and increased emissions.

If the vehicle is equipped with a turbocharger, common problems can include turbo lag, reduced boost pressure, or even complete turbocharger failure. This can lead to a significant drop in engine power and performance.

A worn or broken timing chain/belt can cause significant engine damage. This can lead to improper timing of the engine's internal components, resulting in poor performance or engine failure.

Problems in the fuel system such as clogged fuel injectors, a failing fuel pump, or a dirty fuel filter can lead to poor engine performance, stalling, or difficulty starting the vehicle.

Issues with the exhaust system like a clogged catalytic converter or a broken exhaust manifold can lead to reduced engine performance and increased emissions.

Modern engines rely on various sensors (e.g., oxygen sensor, mass airflow sensor) to operate efficiently. A malfunctioning sensor can lead to incorrect air-fuel mixture, causing poor performance and increased emissions.

Electrical problems such as a weak battery or a failing alternator can affect engine performance, causing issues like difficulty starting, poor electrical system performance, and potential stalling.

Electrical problems such as a weak battery or a failing alternator can affect engine performance, causing issues like difficulty starting, poor electrical system performance, and potential stalling.

Oil leaks can occur from various engine components such as the oil pan, valve cover gasket, or oil filter, leading to decreased engine performance and potential damage.

The engine may overheat due to insufficient coolant levels, a malfunctioning thermostat, or a failing water pump, which can cause serious engine damage if not addressed.

Problems with spark plugs, ignition coils, or the ignition control module can lead to misfires, reduced engine efficiency, and difficulty starting the vehicle.

Issues with the fuel pump, fuel injectors, or fuel filter can result in poor engine performance, reduced fuel efficiency, and engine stalling.

A worn or broken timing belt/chain can lead to engine misfires, poor performance, and severe engine damage if not replaced according to the manufacturer's maintenance schedule.

Faulty sensors, such as oxygen sensors or mass airflow sensors, can cause incorrect air-fuel mixture readings, leading to poor engine performance and increased emissions.

Problems with the exhaust system, such as a clogged catalytic converter or exhaust leaks, can reduce engine efficiency and increase emissions.

Issues with the battery or electrical system can cause starting problems, poor engine performance, and potential stalling.
