I concur with dingaling. The circled object is called a "Air Bypass Valve" according to the toyota 3S-GTE manual. The small vacuum hoses from lead to your A/C VSV near your Brake Master Cylinder so controls your A/C idle up.
My 185 has a high pitched whistling noise that comes from that area while cold. On my car it was the T-VIS manifold located at the end of your intake runners going into the head...
I actually removed the intake manifold without removing the head to repair it....was an absolute bitch of a job but fixed it, and gave me more noticable low-end torque
If it is a vacuum leak, and you have a vacuum/boost gauge you may notice the noise goes away or changes as the vacuum in your drops (when you press the accelerator) mine stops at about 10 In.Hg on my gauge, and completely when the engine warms up a bit...
