Heh, this one is kinda funny. Never had a vehicle that had too much oil pressure. My 87 5.7L oil pressure gauge just started saying that my pressure is far above 60. As I was looking at it, no less. I was driving along and I glanced down at it, and right then it shot as far as that little needle can go. And it has stayed there ever since. So I'm thinking... I don't know... bad sending unit?
