New oil filter bad

[ISHOU]

After changing oil on my wife's Taurus(Non SHO) I started it up and realized I had no oil pressure after 5 seconds. I shut off the car, disconnected the coil wire and cranked the engine for 5 more seconds, started car again and still no oil pressure. Shut car off and thought it must be a bad filter(Motorcraft). Put a new filter(Motorcraft) on and oil pressure returned. Anybody have this happen? Did I do any damage in the 10 seconds it ran with no oil pressure??

I'd definitely let Motorcraft know about it. Could be a defect in a small group of filters, or you got a defunct one...

I've had it happen with other makes of vehicles. But it was not the fault of the filter. It could be just a fluke because the oil filter shouldn't keep the pump from making pressure. You may have a weak pump with excessive wear between the gears. When you drained the oil and refilled it, that may have created an air pocket in the pump gears causing it to cavitate.
