So after 5-1/2 years I finally get my engine started. Once the battery held a charge and it cranked over enough to suck fuel, it started right up. A little loud since the exhaust is not complete.

Anyway, after running the engine for about a minute, I noticed a puddle of fluid on the floor underneath the car. I feared the worst thinking it was gas. Turns out it was coolant. Coming from the bellhousing of the transmission. Now in looking at my spare engine, the only thing I can see where water could come out of is a freeze plug on the back side of the block. Everything looked ok when I put all back together (although I did not change any freeze plugs).

Is there somewhere else the water could be coming from that I can't see? There is no evidence of water in the oil pan so I'm ruling out bad head gasket. And there are no other signs of water anywhere on the engine. What is involved in replacing a freeze plug?

TIA...

Check the back of the head gasket and the coolant tube that runs in that area.
