My son's 1997 Dodge Dakota Sport V8 stalled on him going down the road. The oil pressure gage shows the pressure drops to -0-. We took to a mechanic who put on rack, ran 5-10 minutes and said the motor is "history" - Said needs new motor and to get a crate 318. (We are talking $3500 labor/material). After many tears, I had car-tinkerer neighbor crank. He said motor just sounds too good and runs too easy to be bad. He said he "hears nothing". He suggested a sending unit. Obviously we need a 2nd opinion but I am very scared to get hopes up. Could neighbor be right. Can whatever instrument the mechanic uses on a rack "think" the motor is bad when it is ok?

Get a mechanical gauge and replace the sending unit with it.
Start the engine and check the pressure. Factory say 3psi min
@ idle, 60psi max @ 3K RPM.

Mechanics don't always get it right! I once got a car for the cost of towing it home because the owner was told by a mechanic that it needed a new engine and a new transmission. All the transmission needed was a 25 cent plastic bushing in the linkage. The "knock" in the engine was a broken water pump shaft, allowing the water pump pulley to just bang around instead of driving the pump. That caused the engine to overheat, but they stopped the car and had it towed before it caused any engine damage.
The end result was a substantial loss to the previous owner and a nice gain for me.
Like Daddio said, check the oil pressure. If it is good, and the engine runs good, wait and keep a watch on it. It may be good and the mechanic may just be looking for some extra money ( or too lazy to properly diagnose the problem). I had a 98 Dakota stalling when stopping because the transmission fluid was low.
