Well I was driving the truck tonight and passed a slow car and ran it up somewhere between 100 and 128(overdrive) and slowed back down and my oil pressure is now 15-20 psi lower than it normally is.

I know its hard to tell from this but does it sound like I hurt something? It has no weird noises and drives fine, I drove it really easy the rest of the way home so I dont know what it will do under hard throttle.
