2004 9-5 Arc 2.3. There's a loud wining sound upon hard acceleration and was told it might be a turbo boost leak. Any suggestions on where to start looking? Thanks.

quick home diy method mix some fairy liquid with water shake bottle and spray boost pipes and joints and rev engine see if you get any bubbles, other methods are smoke, pressure tests etc ic could have a small hole to or the turbo going

you sure its not a belt you are hearing

Yes, 2 seperate mechanics said it was a boost leak. Want to troubleshoot myself before handing over my wallet.
