Injector seals are elastic rings intended to seal the mounting seats of the injectors in the cylinder head or intake manifold. Apart from that, these parts allow reducing the level of noise and vibration when the engine is running.
5 tips on how to use and replace them
- Replace the seals every time you dismantle them. These elements, if used for the second time, cannot ensure the proper sealing.
- If you need to install several spares at once, buy an injector seal kit. For example, it is possible to order online a set containing the quantity of elements which corresponds to the number of cylinders of your car.
- Entrust replacement of the parts to workers from a vehicle repair shop. The specialists will install new components with regard to the manufacturer’s requirements.
- Consider the fact that before you mount the injector seals, it is necessary to lubricate them with motor oil and thoroughly clean the contacting surface.
- Pay your attention to the fact that the seals should be able to rotate freely in their mounting seats.
Failures of injector seals, their causes and symptoms
- Cracks, tears. Mechanical damage occurs as a result of a long-term exposure to high temperatures. In most cases, a faulty upper seal can be detected by fuel traces when checking the assembly, a faulty lower one – by white smoke coming out of the exhaust pipe right after the engine has been started. Sometimes a smell of fuel in the passenger compartment indicates to the failure: it can be felt at low temperatures. Besides, the engine works unstable when idling, and its power gets significantly lower.
- Loss of elasticity. It can be a result of thermal damage due to the high temperature of the power unit. It leads to fuel leakage or air getting inside the fuel system. This malfunction is indicated by difficult engine start, its unstable operation, reduced power, increased fuel consumption. Besides, the engine may spontaneously shut down when idling.
