There are several common reasons why your car might be leaking oil:
Gasket or Seal Failure: Gaskets or seals in your engine, such as the valve cover gasket or oil pan gasket, can deteriorate over time and start leaking.
Oil Filter Issues: If the oil filter is not properly installed or if it's damaged, it can cause oil to leak.
Oil Pan Damage: The oil pan can become damaged from road debris or impact, leading to leaks.
Cracked Engine Block: Although less common, a crack in the engine block can lead to significant oil leaks.
Loose or Damaged Oil Drain Plug: The oil drain plug, located at the bottom of the oil pan, can become loose or damaged, causing oil to leak.
