I have been battling a coolant leak on the rear, right-hand side (near the heater core). I am having a problem finding the leak as it only leaks with the engine running. I have put a scope/camera on all the heater core hoses and fittings and have yet to find anything.

I can see it dripping off the exhaust manifold to the floor but, I don't know if that is the leak.

I have ordered a radiator pressure testing kit. I hope I can build up a few pounds of pressure and it will help me locate the leak. Worst-case scenario, I may have to replace the head gasket on that side.
