The effort that goes into keeping a car in good shape is worth it. Taking the time to make sure that all of the vital components of your engine are working properly is an essential part of keeping your vehicle reliable. The oil that flows through your engine every time it is cranked is important in regards to the lubrication that it provides. The oil pump is what gives the pressure needed to get the oil through the engine and to the spots where it belongs. In order for this pump to stay leak free, the oil pump O ring will have to be working properly.

This rubber O ring is designed to last as long as the engine does. The constant contraction and expansion that this O ring undergoes over time will begin to wear down the rubber and make it susceptible to leaking. Since you are not able to see this part on your car, it is important to look for the warning signs that it is going out. Allowing this part to stay in a state of disrepair for too long can cause a lot of damage to your engine. The oil that will leak out of the damaged O ring will allow for a lot of friction for the internal parts of the engine. With that being said, have a professional mechanic replace the damaged oil pump O ring to make sure no further damage is done.

Most car owners never give their oil pump O ring a second thought until there is a repair issue with it. If you are unsure about whether or not the problems you are experiencing are caused by your oil pump O ring, then you will need to get a professional to take a look at it. They will be able to troubleshoot the issues you are experiencing can figure out how to best fix them.

Here are a few of the signs you will notice when this O ring is in need of repair:

  • Low engine oil levels
  • There is oil around the timing cover of the vehicle
  • The intake manifold has a lot of oil around it

Catching these warning signs and getting the damaged oil pump O ring fixed can help you keep your car’s engine running smoothly.
