There are a number of gaskets and O-rings that reside in an engine. Without these gaskets and O-rings, it would be very hard for the various liquids that are in the engine to stay where they need to be without leaking out. Among the most important O-rings that are on your car are the ones that go on the fuel injectors. These O-rings go on the end of the fuel injector to keep it tight against the engine and to prevent it from leaking. This O-ring is used on a constant basis, which is one of the reasons why they wear out on occasion.
Having a properly working fuel injector O-ring is a vital part of keeping the fuel in your engine and doing the job that it is intended for. The fuel injector O-rings are made of rubber and are intended to last around 50,000 miles. Due to their rubber construction, it is very easy for these O-rings to dry out and become brittle and damaged. There are a number of different O-ring lubes on the market that can help them last longer. Taking steps to keep the O-rings on your fuel injectors functional should be something that you take very seriously.
Typically, checking the fuel injector O-rings on a vehicle is not part of routine maintenance. The older that the car gets and the more miles it has, the more of a need you will have of getting the O-rings checked out. In some cases, the O-rings can lead to the fuel injectors being clogged and not being able to perform the job they are intended to do.
The following are some of the things that you will notice when it is time to have your fuel injector O-rings replaced:
- There is a noticeable fuel leak from where the injectors are mounted
- The car will not start
- There is a strong smell of gasoline coming from the vehicle
By taking notice of these warning signs, you will be able to get the repairs needed to restore the functionality to your fuel system. Having damaged fuel injector O-rings can be very hazardous and will result in a loss of fuel efficiency. Visit a professional mechanic immediately to get your car's fuel injector O rings replaced.
