Pull me back from the brink!! Oil Pump Leak!
Finally got the new engine in. And darn if the oil pump isn't leaking at the junction between the pump and block. I used the cheapo gasket that came with the pump -- didn't use any sealant. Did it exactly the way the Mazda service manual said to do it! It's enough of a leak that it really needs to be fixed.
I used Mazda OEM gaskets everywhere else -- no other issues, even my BEGI reroute spacer is sealed up tight.
What would you guys do?
1. Pull the engine again?
2. Drop the subframe and do it all on your back?
3. Take the darn thing to a shop (assuming there's one you can trust)?
4. Other?
Very frustrated.

I may be jumping the gun. Looking at other threads, there are all kinds of places that pressurized oil can get out of. I think step one is to take off the timing belt covers, clean everything up, and run it with dye.
Still frustrated.

I'm going to dye test tonight and make sure that it is coming from the pump and not something like a cam seal above. It it's the pump, then first attempt will be to pull one bolt at a time, chase and clean the threads and then retorque while making sure none of the bolts are bottoming. If that doesn't do the trick, then it's time the pull the engine. I guess even if the references don't show an O-ring, if there's a spot for one what can it hurt, right?
Sound reasonable?

No, it doesn't sound reasonable.
If you didn't put in an O-ring, man up and just pull the damn engine.
O-ring groove clearly visible here, right by the pressure relief valve:
It's hidden by the paper gasket, which is kind of weird. But I've had no issues sealing the pump to the o-ring, o-ring to the gasket, and the gasket to the block.

My oil pump on my bp motor doesn't have the groove for the o ring. The older BPs dont have that groove. I think mazda updated the design to decrease oil leaks. I can post pictures later. I have two of them that are this way. I would use some black sealant for the gasket insteaed of the paper gasket.

I honestly did not notice whether I had an O-ring groove on the new oil pump. No O-ring came with the pump.
