Oil Seal Replacement Service

What is the Oil Seal all about?

Your car’s engine produces the power necessary to move the car down the road, and the transmission’s job is to deliver that power to the wheels.The engine has to connect to the transmission in order to transfer motive force. The stationary gear helps with this (it acts as the go-between for the engine and the transmission). Of course, there must be a system in place that will allow the stationary gear to turn and simultaneously prevent engine oil leaks – this is the task of the stationary gear oil seal, or an O-ring.

The stationary gear oil seal is located behind the gear itself, from the perspective of looking at the engine from the rear, with the stationary gear on the outside. It’s really nothing more than a rubber circle that fits into the space between the engine housing and stationary gear. Over time (and through a lack of regular maintenance), the O-ring can become brittle. When this happens, it will crack and begin to leak, at which point replacing it is the only option.

Keep in mind:

  • All engine oil leaks can and should be detected during regular maintenance.
  • Routine oil changes and usage of quality engine oil will delay oil seal degradation.
  • A leak from the rear main seal will mirror a leak from the stationary gear oil seal.

Our recommendation:

If you notice oil leaking from the connection of the engine and the transmission, your car has a serious problem. Both the stationary gear oil seal and the rear main seal are located in this general area. Having the problem diagnosed and repaired by one of our expert mechanics is vital.

What common symptoms indicate you may need to replace the Oil Seal?

  • Oil leaking where the engine and transmission meet

How important is this service?

With time your engine may develop leaks -- gaskets and seals dry, shrink, and crack. It is imperative that you keep up with regular maintenance, and that includes replacing leaking gaskets, oil seals and O-rings before the problem becomes too serious. A leaking oil seal will compromise engine performance.
