Symptoms of a Bad or Failing Oil Pump O-Ring

The lubrication that the oil in your engine provides is an essential part of having a smooth running engine. There are a number of internal parts in the engine that will have to be lubricated in order to function properly. It is the job of the oil pump to ensure that the right amount of oil is put into the engine. In order to maintain the right amount of pressure, the oil pump is sealed off with a rubber O-ring. The gaskets and O-rings that are on an oil pump will perform a very specific and important function that is vital to the running of your engine.

Any part on a vehicle that has to do with the oil is important and should be monitored. Having a bad oil pump O-ring can be very harmful to the engine if not caught and fixed in a hurry. When there is an issue with the O-ring, here are some of the things that you may notice:

1. Engine oil level is low

Having an oil leak can wreak havoc on your engine due to the lubrication that it takes away from the internal engine part. The leak can severely lower the oil level and oil pressure inside the engine. Checking the oil level in a car on a regular basis is important due to the warning signs it can give you when something is wrong. If the oil level is low, then you will need to inspect the oil pump to see if the O-ring has been damaged.

2. Leaking oil covering other parts of the engine

When an oil pump O-ring begins to leak, it will usually soak the other parts of the engine with oil. The oil pump is commonly behind the crank pulley which will sling oil around the engine bay. Usually, you will begin to notice that there is oil all over the timing cover and the intake manifold. Acting quickly to get this problem fixed can save the other components of the engine from becoming damaged due to the leaking oil.

3. Puddles of oil underneath the car

Another very common sign that you will notice when it is time to replace the oil pump O-ring is a puddle of oil under the car. Having this much oil leaking from your car can cause a lot of problems with the internal components. Finding and fixing the issues that are causing this leak is important in maintaining the functionality of your engine.
