oil pumps are in the sump and run in oil
there is no bearing as such as the shaft and gears are just a close fit in the cast housing which is lubricated by passing oil under pressure
as for a noise, if you can hear it there will be little or no oil pressure
However water pumps bearings regularly fail and you will hear it. mostly a sort of tinny rattling noise or a low grumble.
Sounds like thay unhooked your cruise control.and check your a.I.c sensor.Air idle control sensor.sometimes called map sensor.if all is good with the sensor.the problem could be deeper
I have heard that Fords theory behind that is to supply maximum oil pressure to moving parts sooner. All the Ford products do this and the motors last well into the hundreds of thousand of miles. I wouldn't be to worried about it since there is no issue with it to my knowledge and there is no way to limit the cold start RPM's.
Cold start warm ups are a thing of the past. Better lubricants, engines, fuel injection and other computer controls have made start ups easier on the engine. 30 seconds is barely enough time to warm up anything and after a few seconds oil has already reached all of its intended lubricating points. That first few seconds is the hardest on the engine. Regardless of how any RPM's it is turning.
