93 crown vic leaks coolant at oil pan

Car overheats after about an hour of driving. Coolant leaks under car at the oil pan or @ least thats what it looks like. Water Pump good,thermostat good, heater core seems to be working Ok . PLEASE HELP TRYED JUST ABOUT EVERYTHING !!!!

Try to look right under the intake manifold, there is hose running under it, that is usually the problem. Good luck...
