Among the most important parts of an engine is the oil that it contains. Without the right amount of oil pressure in an engine, it will be hard for all of the moving parts to get the lubrication that they need. It is the job of the high pressure safety valve to ensure that the right amount of oil pressure stays consistent. Once the right oil pressure is achieved, this safety valve will turn down the oil pump to reduce the amount of pressure that it is putting out. Usually, the oil pump will have to run its hardest when the car first starts up.

Typically, this valve will last as long as your car does, but there are instances when it will have to be replaced. Much like any other switch or valve in a vehicle, the heat of the engine can affect the way that the high pressure safety valve operates. Since this part is not checked on a regular basis, the only time that most car owners will have any interaction with it is when it becomes broken. Dealing with the broken valve as soon as problems start to surface can help to prevent a lot of damage.

Getting the damaged high pressure safety valve replaced is a job that is best suited for a professional. The oil pressure is a vital part of your engine and attempting to fix components of this system without the right amount of experience can lead to less than stellar consequences. A professional will be able to troubleshoot the issues with your oil pressure and get the right repairs made in no time. When the high pressure safety valve in your engine is damaged, here are a few of the things you may start to notice.

  • There is a sudden drop in oil pressure
  • The Check Oil or Low Oil Light comes on
  • The engine is performing poorly
  • The oil pressure will stay on the low end of the gauge

Finding and fixing the issues with your car’s oil pressure should be a priority. Running an engine with low oil pressure levels can lead to a lot of problems and will cause a lot of damage.
