You can but istill dont' think that is it.

Hmac300, what do you think it is? Your answer indicated it would be one of the two, now you say neither? What is your suggestion?

All I meant was that you can check both things but I dont' think that is it. I really don't have any inclination as to what it could be. Maybe a brake booster but I doubt it. I really don't have an answer, it really doesnt' soundlike anything serious. The only possible thing I could think of would be something on the exaust system but I think it runs down the other side on that vehicle.

Anyone have a suggestion? Something is not right and can't pin point it?

The only other possible thing I can think of is the fan making the noise as it is electrically controlled on this model along with a belt. That is about it, it is extremely hard for us to try to diagnose noises due to not being able to hear them as well as so many noises it could be.

AIR DISRUPTION AS IT ENTERS THE THROTTLE BODY. KAZOO EFFECT?
AS SUGGESTED EARLIER, DID YOU ACTUALLY REMOVE YOUR BELT AND FIRE UP YOUR ENGINE FOR A MINUTE OR SO?
THIS WOULD VERIFY OR ELIMINATE A BELT DRIVEN COMPONENT BEING THE RACKET MAKER
1/2" - 3/4" DIAMETER PIECE OF HEATER/ GARDEN HOSE MAYBE 3-4 FEET LONG
SHOVE ONE END IN YOUR EAR, USE THE OTHER SORTA LIKE A STETHOSCOPE
DO A REAL FAST SEARCH WHILE IT'S MAKING THE RACKET
CHECK YOUR BELT DRIVEN ACCESSORIES THIS WAY TOO
BE MINDFUL OF THEM PESKY MOVING PARTS. THEY WILL BITE YA!
AT MINIMUM TRY TO FIND THE AREA A LITTLE BETTER----POINT AT IT WHILE YOU SNAP US A PIC
AS FAR AS STUFF YOU HAVE RECENTLY REPAIRED. YES. EVEN BRAND NEW STUFF CAN BE BAD, AS WELL AS IT CAN GO BAD AT ANYTIME

The issue is fixed. It was the smog pump making all the whinning noises.
