BMW Oil Leak

BMWs are safe and dependable vehicles that provide outstanding performance. Drivers know that they need to stay on top of maintenance to get the best out of their BMW. Without maintenance, you may experience an oil leak.

Your BMW’s engine is a complex machine composed of several parts. These are constantly under stress. For your engine to function properly, it needs oil, which lubricates the moving parts and absorbs heat. Without the oil, the friction between the components will cause damage and excess heat.

Driving with an oil leak can be dangerous. The leak could cause a fire, and you may also experience engine failure, which could lead to an accident.

Symptoms of an Oil Leak

There are several symptoms you may experience when your BMW has an oil leak. These symptoms include:

  • a puddle of oil under your vehicle
  • engine overheating
  • the smell of burning oil
  • smoke coming out from under the hood
  • sizzling noises
  • the check engine light turns on

Causes of an Oil Leak in Your BMW

Oil is necessary for lubricating the components in the engine. It cools the engine while preventing premature failure. There are many issues that can lead to an oil leak, but most of these issues are preventable with regular maintenance. The majority of oil leaks are produced by damaged oil seals, oil pans, or engine gaskets. Some oil leaks can be easily fixed. While others are caused by major issues.

Common causes of oil leaks in a BMW:

  • Oil Filter Issues: Having your oil filter changed during your oil service will help to prevent an oil leak. A dirty filter will get clogged and prevent the oil from flowing properly.

An improperly installed filter can also cause a leak. If the filter is not tight, oil can leak around it. Using the wrong oil filter is another reason for oil leaks.

  • Drain Plug Was Not Installed Properly: If the oil leak starts right after an oil change, the plug may not have been installed properly. It may be loose or damaged.
  • Loose Filler Cap: An oil leak can occur when the filler cap is not tight. This often occurs after an oil change. A loose cap lets the oil leak out. The oil then runs down the engine.
  • Damaged Oil Pan Gasket: Over time the oil pan gasket is subjected to an extreme amount of heat. This will cause the gasket to fail over time. When it fails, it will not be able to hold the oil in.
  • Valve Gasket Seal: The valve gasket seal will eventually wear out. If your BMW has high mileage, the seal could have failed.
  • Rear Main Seal: The rear main seal is located between the crankshaft and flywheel. This component is more susceptible to failure if you skip oil changes or rarely drive your car.

Preventing Oil Leaks in Your BMW

Preventative maintenance is the best way to prevent oil leaks. Oil can break down as it ages and become contaminated. Dirty oil will lead to component damage. Changing the oil regularly will help extend the life of your engine. It is important that you follow your vehicle’s maintenance schedule. Doing so will extend the life of your car and prevent oil leaks.

Regular oil changes have many benefits, including:

  • removes contaminated oil
  • extends the life of your engine
  • increases your gas mileage
  • provides proper lubrication
  • helps keep the engine and its components cool
  • protects the environment by reducing pollutants
