freeze plug leaking

when i was breaking in the cam on my 360 one plug went flying lol so ya i did replace it with the motor in the car. it was the next to front one on the drivers side. with the power steering it was really hard and it is not in 100% straight. so i would pull the engine and do it. the engine is probably leaking in a place or two that you have not seen yet so then you can relace all that needs replaced and it will be better
