My Ride: 2001 325i 5-spd
Engine noise ~5k RPM

Hi everyone, I just picked up a '01 325i two weeks ago and have experienced a whole run of typical problem with a 11-12 year old car but got a couple of questions left. Mileage is ~187k

@ ~5k RPM the engine makes a noise that sounds similar to a blow-off value. It's a semi-high pitch noise, I figure it is a pulley bearing but wondering if anyone has experienced this or knows which ones go first and if they can be re-greased or requires replacement.

The other problem I'm having seems to be the ICV (I did some research on the forum first). The engine is rough at idle only when cold and will stale occasionally if the clutch is depressed (first light or so). Also, it requires a bit more revs to move otherwise it stalls (only 1st/2nd from cold start). From what I've been reading, it seems the ICV or cracks in the system before that, but is there anyway to check that before disassembling a lot of pieces?

So far I've replaced the spark plugs, air filter, rear brakes and sensor, and calibrated the emergency brake after checking the pads all by DIY from links form here or YouTube. This car is amazing to drive but is an annoying PITA at times, hopefully with some help I can get it running (and stopping) perfectly again for another decade!
