Hey guys, just like the the title says. I have a coolant leak and it on the rear of the block. I felt back there and its doesn't seem like its the heater hoses. Does anyone have any suggestions? I was told it was a Blown Head Gasket. But it doesnt have the symptoms of having a blown gasket i.e. (milky oil, water from exhaust, white smoke). Can anyone Help!!! PLEASE!

we can only guess, you must get an inspection mirror and identify exactly where the leak originates...could be a heater hose, under plenum water hose, seeping freeze plug, or a real gasket issue.....no way to tell without looking.

Always possible that you have a leak under the plenum and it's blowing back too... although it would have to be quite a leak... lots of places to trap fluid under there. You can get a coolant system pressurizer as a loaner tool at Advance Auto or places like that that helps find these things more easily.
