EA82 Backup / Coolant Passage O-Ring

Recommended Posts

Hey guys, I'm at the midway point on a full split-block, bearings-up rebuild.

I've got all my big parts back from the machine shop, but the backup o-ring, also referred to as the coolant passage o-ring, from inside the block is gone.

 

I've read that they come in a Fel-pro full gasket set, but I already have all my other gaskets, so any idea where I can find one on its own?

The "back-up" ring can be reused. But here are the Part #s for both

 

Backup ring - 11070 AA000

 

O-ring - 11071 AA000

 

 

These are old numbers from an '85 factory parts catalog. They may supercede to a new stock #s.

 

Should be able to order from any subaru dealership.

Thanks for the info. Those parts numbers were good, one part was the orange rubber o-ring, the other is the metal clip reinforcement that hold the rubber in the correct shape. Each part was less than $5. Hopefully this thread helps someone else.
