Subaru B9 Tribeca Distributor o-ring replacement
Subaru B9 Tribeca distributor o ring replacement
If your early model or classic Subaru B9 Tribeca has been leaking oil from the base of the distributor, it’s usually a sign that the distributor o-ring has failed and needs replacing. Because the distributor shaft enters the engine, a seal is required to stop oil from exiting the Subaru B9 Tribeca’s engine and to stop contaminants from entering.
Since the Subaru B9 Tribeca’s distributor is responsible for ‘telling’ the spark plugs when to fire, the timing needs to be precise. If a distributor moves out of alignment, it can create major timing issues and cause damage to the engine. When the spark plugs ignite the fuel at the wrong time, all other elements are no longer in sync and clean and efficient combustion can’t be achieved. This is when engine damage can occur on a Subaru B9 Tribeca.
If the o-ring fails, it will need to be replaced as soon as possible. This can cost around $50 to $160 depending on the Subaru B9 Tribeca and how easy it is to access the distributor. Leaking oil around the engine can create issues for electrical connectors and components inside the Subaru B9 Tribeca’s engine bay. Also, if the distributor is not sealed properly it can cause engine damage. Best to have it fixed as soon as you can.
