dlongnecker did you ever figure out what was wrong with your van. We are having the same situation with our van. I think we took it a bit too far though. I filled the coolant back up, and now it is really leaking out the back end of the motor by the belt. Trying to decide if it is a bad intake valve or a bad head gasket. Also when I tried driving it again after refilling it back up with coolant, blue smoke was pouring out the tailpipe. Leaving me to believe it is the head gasket. But the oil and cap look fine to me, no greyish gunk in there.
