Changing my oil yesterday and I brain farted: I loosened a bolt next to my oil filter and neon green foam started spewing out along with a hissing sound... yikes! (I had forgotten the oil plug has it's own hatch on the belly pan). I quickly re-tightened it, but the the foam continued to leak and hiss, albeit slowly. At first I thought it was the drain plug for the cooling system, but coolant in the Dart is purple. I peered through the opening in the belly pan and it looked like the plug was to the A/C compressor. So, my concern is despite re-tightening the foam continues to leak and foam. What should I do?
