2010, 90k miles, eight hot summers in Houston.
I had a grinding / fluttering / hissing sound coming from the right front of the engine. I thought it may be the turbo (has a small oil leak), an exhaust leak, or something else engine related since it varies by RPM and not road speed. It goes from a loud, metallic grinding when the car is cold pulling out of the driveway to a more quiet hiss or whoosh sound when the engine is warm.
After doing a bit of research, I replaced the upper right engine mount (31257674) and the torque arm (31430441). The mount was clearly bad and the torque arm was noticeably deteriorating. It took a total of an hour, a 15mm socket and breaker bar, and a floor jack to support the engine.
8320
Old mount still installed
8318
Old on left, clearly shot
8319
I also took some before and after video but there is not a significant difference so don't diagnose by movement only.
