horrible coolant leak...ideas?

I had a coolant leak on the left side of the lower intake manifold...and another one behind the timing chain cover.
I took everything apart, then cleaned and resealed everything.
Reassembled everything...started running water through the coolant system to flush it out [really icky] and water starts POURING out from under the car.

I can't actually see where it's coming from, but when I'm up under it on the driver's side, it looks like it's coming out the side of the oil pan near the engine mount bolt. [I know it's not coming out of the oil pan, but that's as far up as I can see.] From the top, I can't see any water coming out. I can see one freeze plug from under the car and it's not leaking.

Anyone have any ideas about what on earth could have happened? I swear it held coolant last summer when I was working on it.

I have lost a freeze plug...the one up under the engine mounting bolt.
Anyone have tips on getting to it?

It's a pain... Lift the motor and remove the mount...
