1994 Dodge Ram 1500 Question: Oil pressure gauge variation



Visitor, 5.9L V8, Bedford, KY, April 26, 2011, 07:08

When I start the truck up the oil pressure gauge reads normal. When I accelorate the oil pressure gauge drops to almost nothing. If I let off teh gas the pressure returns some. Is this a sensor issue or an oil pump issue?

    I've seen this before in high mileage trucks of varying makes. In most cases the oil pickup screen (attached to the oil pump)is/was clogged, allowing just enough oil through at low RPM's, and very little at higher RPM's.
    The oil pan will have to be pulled to verify the problem either way.
