I've read on this forum several times that the genuine Subaru cam tower o-rings on the Loyales was metal reinforced or something?


I just got a pair that I ordered using a part number that I got on the forum here and they cam in little sealed bags that seem to be genuine Subaru o-rings but they have no metal. They are entirely rubber and they came from Subaru Parts Warehouse.


Did I get scammed? Maybe they no longer make them with the metal? Maybe I misunderstood all along what they should look like.


Mine is a '91 and the o-rings that cam out were all rubber (brittle but rubber).

13089AA010 is the Subaru part number for the reinforced O-rings.


I've used that number on a few different orders, got the proper ones each time.

  ++ what tom said,,  they are not metal,, folks say that because they seem hard and almost seem to be.  they are rubber covered and some type stiff material, they do not deform shape under pressure of compression when the case is tourqued onto the head, and the rubber forms a seal for the oil.   they should look more like a rubber coated washer than an o-ring ,  and be pretty stiff.   if you use standard rubber orings they squish and block the oil hole.   i only wish they had done something like this and as well as this for the mickey mouse gasket on the oil pump.

Well they are flat and look something like a washer, yes, so maybe I have the right part.


The old ones that were not 'metal reinforced' - they just looked like a standard o-ring?

the old ones often deteriorate to a state where they resemble brittle rubber rings. just make sure the new ones are firm, not like a regular oring
