Mark, take a finger or two and feel under the water neck/thermostat housing at the front of the intake manifold that the expansion tank connects to. If it's damp then that's your problem. Also check the tightness of the two thermostat housing bolts. They shouldn't be torqued too tight (it is aluminum!), but vibration has been known to loosen these. Also a good look from underneath with a flashlight will usually allow you to "follow the trail" and you can see where the water is originating from better. Good luck!
