Bart, you sure this isn't comming from the water pump weep hole? When the pump begins to wear out, small amounts of coolant will drip as a warning. Keep a close eye on that temp gauge till you find out. The pump goes, it'll take that engine with it pretty quick.
Chop, I'm not sure about anything. Its been like this for well over a year with no apparent ill effects, so I don't know. Maybe I should take this issue to a radiator shop...
Where is this weep hole? Is this something I can evaluate myself?
