Corvid Posted September 6, 2012 Share Posted September 6, 2012 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?

Gloyale Posted September 6, 2012 Share Posted September 6, 2012 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. Quote Link to comment Share on other sites More sharing options...
Corvid Posted October 10, 2012 Author Share Posted October 10, 2012 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. Quote Link to comment Share on other sites More sharing options...
