What to know about the Oil Pump O Ring:
In order to grease the engine, oil must be pumped up from the pan through the engine. This process, which is done 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 appropriately maintaining your car with consistent oil changes can exacerbate the problem and increase the speed of the aging process. Over time, the oil pump O-ring can break and begin to leak. It can be tough to analyze this type of leak, which is easily confused with a front main seal leak or other leaks. The only method of confirming the leak source is to take out the timing cover. Changing the oil pump O-ring will require removing the oil pan from the car. We recommend changing both the pump and the O-ring simultaneously.
Facts to Note:
While oil leaks can be observed and spotted during consistentupkeep, confirming an oil pump O-ring gasket leak will be challenging without considerable teardown.
The best prevention method for any form of gasket or O-ring failure is regular upkeep.
How to Fix:
The vehicle is lifted and held on jack stands
The faulty oil pump O-ring is removed
The new oil pump O-ring is fixed and fluids are filled
The vehicle is removed from jack stands
The vehicle is started and checked for oil leaks and correct operation of the oil pump
All engine oil leaks are serious, as even minor leaks will lead to major problems. Low oil levels will cause immense damage your engine. Have your engine maintained by one of your expert mechanics.
Common symptoms indicating you may need to changethe Oil Pump O Ring:
Low engine oil
Oil visible around the timing cover
Oil visible around intake manifold
Importance of this service:
Changing a failed oil pump O-ring is very essential. Left unfixed, the problem will only worsen. It’s recommended that you change the oil pump at the same time, since the old pump must be removed anyway to replace the O-ring. Make sure you’re working with one of your expert mechanics capable of providing you with an accurate analysis, as oil leaks of this nature are notoriously difficult to pinpoint.
