Hello, I have an 09 eos 2.0 that started making a terribly loud squeaking noise when idling. The noise stops when given throttle. No belts or pulleys seem to be loose. I replaced the intake manifold and a brand new turbo (both pain in the butt jobs). The intake manifold and turbo both turned out to be broken. However, this did not fix the problem. The noise started again once the car heated up and the turbo doesn't seem to be making boost. Has anyone else had this problem? I would greatly appreciate any advice you might have.
Thank you.
