e30: A/C noisy during idling

[selespeed]

hi all experts out there; i had a reconditioned A/C compressor Sanden SD-507 replaced last week but there's a lot of noise during idling. it sounds like it is metals hitting each other hitting "tok tok tok" like rattling in resonance. the noise disappears when i revved up. i went back to the A/C specialist but they still could not solve the problem however they twist, turn the pipes to try to solve the noise. finally i think it may be due to the compressor pistons being noisy and perhaps the noise is just "deadened" when i revv up. what do you guys think? the noise is extremely irritating during idling and even at 1000 rpm. thanks all!

You sure its not from the loose plate riveted which is holding on the aircon compressor pulley thats making noise?
