i really dont think theres anything under your hood that isn't already heating your oil, thats going to make it any hotter, the engine temp is all relavant, the oil flows through out the entire thing, maybe this braided line of yours collapsed and is pinching off oil pressure, or something of that nature.... but if there was something inside your engine to superheat your oil enough to mess up something... then it would have superheated your entire engine.

now heres a little help.... check that braided line... next, your headers can get a little hot and that braided line would expose the heat to the oil, a hot enough tempature could make the oil kinda breakdown... especially if you're running something like a 10-40.... if the line is ok... give it an oil change... and i have a feeling everything will be ok
