Started the truck (08 4.3) this morning and backed out of the driveway. I see this huge puddle of water. Not oily at all so im assuming AC condensation but the AC was not on. i had only let it idle about 15 seconds before backing out. It wasnt there before i started the truck. Its coming from the engine compartment. Any ideas? I just has the oil pan and valve cover gaskets replaced last week if that make any difference.
