2002 Explorer
I have a 2002 ex Eddie Bauer 4.0l and while driving down the road my low oil pressure light flashed and the temperature went about 3/4s of the way up and the vehicle died, and then a huge puff of white smoke came from under the hood, I pulled over and let it cool when I noticed there was some burnt foam and what looked to be a wire with a torx screw holding it down but the wire looked burnt as well. Also it sounded like something was clacking as I was pulling over

What would cause this?

I took some pictures but have to find a way to post them

Not sure where to go from here
 






I pulled the knocker sensor out, and the wires are Fried, any idea as to what would have made that area heat up like that?
 






Was oil leaking there and combusted? Which would require 400 degrees or so. Seems unlikely.

Could rats have made a nest which melted? If they'd used plastic etc. Not sure what it was you pulled out of the area.

The clacking was most likely a knock, as the knock sensor wire was destroyed and the sensor no longer functioned.

I didnt notice any leaks of any kind, it is a daily driver and has been for the past 3 years so not sure if any rats or animals could have built a nest. I purchased a new knock sensor today so hopefully that fixes the issue.

Only thing im not sure of is how/why it melted in the first place
