I looked through a couple of threads on this matter and they were all about 2.7 engines.

I split one actuator from bank 4-6 (2.5 base), and it`s clearly different from the one pictured on the previous page in this thread (2.7). If you go back in the thread you can see both side by side. Mine had no problem with the large green O-ring, does not even have it. So is it because it`s model specific (2.5 vs 2.7) or because the one that usually fails correspond to bank 1-3? Can anyone confirm either this or the other possibility?
