    After a while of my 1998 explorer running, I noticed that there was smoke coming from some sort of muffler under the rear area of the engine. Idk if some fluid was dripping onto it in which I am doubtful, or the muffler was just doing it for some reason. Help me out guys, I can't drive it if its on fire!

    Most likely a valve cover gasket is leaking a bit of oil, which then drips down onto the exhaust line and burns up.

    I think you're referring to the catalytic converter located under the transmission/rear engine. You probably have a valve cover or rear main seal leak that's dripping on the converter. Pretty common issue on the V8's and not really a big deal unless the leak gets bad.

    Could be the oil pan gasket. I had a problem with my oil drain plug leaking and causing it to smoke

    Keep an eye on your oil level.
