I installed new injectors in the LT1 and upon first startup, the o-ring seals were leaking just a bit on every injector. Is this normal?

No that is not right, did you lube the o-ring before install?

Yea, the o-rings were lubricated. Maybe I'll replace the seals and see what happens. It's easy to pop them out.

Did you re-use the stock seals?

No they were brand new seals that came with the injectors.

NonGoggleGuy

Then I'm not sure WHY they're leaking, but they shouldn't be.

Thanks beedo and NonGoggleGuy for your helpful responses. It ended up that a few of the injectors had defective pintle caps and were leaking before the lower seal, so the fuel flooded upward out of the injector opening. So I bought new injectors and I expect everything to be fine.
