ok everytime i start my car up in the morning it makes a high pitch screechin noise...i startd noticeing it after the TB Bypass but i know that cant be it ... the hose doesnt come in contact with the pulley. After like 2-5 minutes it will just go away, i just think its really annoying...any comments??

Air pump going south maybe? Second guess would be a tensioner.

Does it sound like it could be the drive belt? Have you tried popping the hood after you start it up to pinpoint the sound? That would really help.

it sounds like it could be a belt. It only happens in the morning lately cause its been pretty cold down here...

Make sure the clamps are tight on the TB Bypass cause it is routed directly over the belt and pulleys. Maybe slight static leak that is saturating while the car is sitting. Its a thought...

Sounds like coolant got on the best, it could be glazed, or just stretched out and worn.

Take the belt off the crank pully, start it up and see if the noise is still there.
