Thanks for the advice, AJ. I’ll wipe it clean and watch it again. It sure seemed like it was weeping out of the metal. I know that sounds hard to believe, but I wondered if Father Time had eroded pin holes right through the metal
You can go to your friendly auto parts store and they will lone you out a cooling system pressure tester. That way you can pressure up the system when the engine is cold, then you can use your hands to find the leak without getting burned.
