I have replaced by 03 + O2 at least twice each and they indeed have to 2 O-rings I do not know the size of the O-rings cuz I got them from the dealer. Sometimes one gets stuck down in the engine that you have to dig out. It's also been my experience that if you don't replace the sleeve it would start leaking quickly. There should be a little bit of play for the snap ring to go in from shouldn't have to push the sprocket down
