im getting a whining sound somewhere around the intake manifold.... but just cant pin point it. It normally happens when i cruise on the freeway about 70ish but goes away if i run at slow speeds or turn the motor off for a few. if anyone has any ideas let me know this whining is getting really annoying lol

also i know its not a bearing checked them all out and their in good shape

 

I remember that my old '92 Nissan Hardbody's Fuel Injectors "Hummed" at about 70MPH, it sounded COOL!

Fuel Injectors making a racket? Otherwise, i don't think that there's anything else around the intake to be making noise...

Are you ruling out the "squeal" of a worn or loose belt, at the P/S Pump? Maybe it could be the P/S Pump itself?

 

Might try marvel Mystery oil in the fuel or some good fuel cleaner and lube and belt dressing to see a noise coming P/S or alt check belt tension slip at higher speeds
