Car oil leaks can be a common issue faced by car owners in the United Kingdom. Such leaks can lead to serious damage to the engine if left unattended. Understanding the causes of car oil leaks is crucial in preventing further damage and ensuring the longevity of your vehicle.

One of the main causes of car oil leaks is a worn-out or damaged gasket or seal. These components are responsible for keeping the oil inside the engine and preventing it from leaking out. Over time, due to wear and tear, gaskets and seals can deteriorate and develop cracks, leading to oil leaks.

Another common cause of oil leaks is a faulty oil filter. The oil filter is responsible for removing impurities from the oil before it reaches the engine. If the filter becomes damaged or clogged, it can cause oil to leak out of the engine.

Additionally, loose or damaged oil drain plugs can also result in oil leaks. The drain plug is responsible for draining the old oil during an oil change. If the plug is not tightened properly or becomes damaged, it can cause oil to leak out.

Moreover, excessive pressure within the engine can also lead to oil leaks. This can be caused by a malfunctioning PCV (Positive Crankcase Ventilation) valve, which is responsible for regulating the pressure inside the engine. If the PCV valve becomes clogged or fails, it can cause excess pressure and result in oil leaks.

Lastly, physical damage to the oil pan, such as from hitting a speed bump or debris on the road, can cause oil leaks.
