last night our 06 caravan developed a leak (I noticed it after the wife left for work there was a good sized puddle in the driveway). I picked up the van from her work and there was another puddle and that looked to be at the back of the engine on the drivers side. I got it home and got under it to look the engine is completely dry no visible leaks from the oil pan, oil filter or the valve covers. When I checked the oil the level was at the fill mark (about 1 quart low). The k member has a little oil/fluid on it but everything above that is dry. I guess it could be the rack but the fluid level hasn't dropped and everything looks to be dry.
Any Ideas?
