I seem to be losing oil pressure. When it is first started (cold) it will have about 25 psi at idle and 45-50 psi at 60mph. However, once it gets warm the oil pressure drops to 0-5 at idle and about 25 psi at 60 mph. I first thought oil pump but since it is seems relatively good when cold I don't think that is it. Anybody have an idea?
I would change the oil sending unit,may be reading wrong.
Sending unit is fine. Any other idesa?
