Quick question. When I replaced the large oring seal on my oil pump (4cyl '98 engine) I removed the large circular rotor for a moment to look at it and inspect it. I was just reading about making sure that the arrows(on the rotors) are pointed out when reinstalling the rotors.
See step 42 on this link for clarfication:

If for some reason the larger rotor was not installed with the arrow pointing out would I know it at this point... The engine seems fine mechanically and I've driven it some time since the o-ring repair. But I gotta know....

I think I may have unconsciously seen the air and set it correctly but its a nagging thought in my head at this point.
