Oil Pressure


Asked by Oct 16, 2014 at 04:34 PM about the 1967 Chevrolet Malibu

Question type: Maintenance & Repair

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?
