Mystery Puddle, Condensation perhap? Options

[cccbock]

Just to set the stage, I live in north Florida where this past week it was freezing, and the the past two days are 80 degrees. The car is a 96 Z28 with LT1 heavily modified. Which means a cast iron block, and Big Canton pan full of 40 weight oil.

So I go out this morning (70 degrees, 90+% RH) and there is an acutal large puddle of water under my engine. It seems to gather approximately at the rear of the block on the concrete floor. If I were betting man, I would have put my money on the crossover tube connections on the back of the heads...but they are dry as a bone.

I check radiator and overflow...both full. So maybe last weeks rain blew into the garage...nope, then other stuff would be wet too.

Lift car and ther are NO obvious places that appear to be leaking...no puddling at all under the front half, so I rule out radiator and hoses pretty much. There is slight oily/watery slime on the bottom of the oil pan where it appears the substances have been mixing.

Anybody have experience with an engine generating enough external condensation to have it pool under the car? The conditions have been just right for this to happen here where I live, but I'll be damned if this isnt the first time Ive ever seen it.

Weird.

Quite possibly. We frequently come out in the morning, and as I'm passing by my 2500HD, I will see little puddles under the diff center section and engine. Those spots are gone by the time we get home in the afternoon. I _think_, if you have antifreeze mixed in, the spots will still be there after things warm up. You should also see the drip spot on the engine.

The metal bits get cold at night, and are prime points for condensation. If there is antifreeze in that, the drippings should taste sweet. Try it, and see.

Here's hoping it's condensation.

Possibly the relative heat capacity of the engine compared to everything around it caused it to be a giant source of condensation as the warm humid air moved in and hit the cold engine (while everything else around it warmed up more quickly). That'd be my guess. Kinda like a supersized can -o- coke on a summer day.
