Sorry to hear this happend.
To date I have never had one of the through bolt o rings leak. It sounds like you could have one of a few things going in:
- when tightening, the washer rotated and cut the o ring.
- when the o ring was installed over the threads, it was cut
- the underside of the washer might have debris from previous build that was not cleaned.
- case spigot surface is compromised, not flat, or has debris remaining from prior build.

Sorry this has happened to you. But looks like you gotta pull it all out to double check.
