    Default Oil pump bad?

    my oil pressure drops down to 0 when engine temp gets up ,,,, she runs at about 215 degrees,,,ive tried thicker oil and it seems to help but after a few hundred miles it does same thing,,,, pressure is 45 when oil is cold,,, seems like I need a new pump,,,,, yes ,,, no ? are all pumps created equal? or should I search for a high flow ?

    Is the engine sluggish at all?

    If not then I would say you might need a new oil sender unit.

    no,,, engine is strong,,,,oil pressure only goes low at idle,,check guage light comes on,,, but as soon as I idle it up the pressure comes back up

    I would replace your oil sending unit first. It's fairly common on our jeeps for that to happen
