Nissan Xterra Oil Pump O Ring Replacement at your home or office.

What is the Oil Pump O Ring all about?

In order to lubricate the engine, oil must be pumped up from the pan through the engine. This process, which is performed by the oil pump, requires a gasket or “O-ring” to ensure that oil does not leak out past the mounting location. While oil pump O-ring failure is rare, it does happen.

The oil pump O-ring becomes brittle over time and through normal wear and tear. Not properly maintaining your car with regular oil changes can exacerbate the problem and increase the speed of the aging process. Over time, the oil pump O-ring can crack and begin to leak. It can be difficult to diagnose this type of leak, which is easily confused with a front main seal leak or other leaks. The only method of verifying the leak source is to remove the timing cover. Replacing the oil pump O-ring will require removing the oil pan from the car. We recommend replacing both the pump and the O-ring simultaneously.
