GoPro footage of my engine showing how much the drivetrain can move around, even during normal low-key stop and go.
Bonus in-cabin open wastegate pulls at the end.

I used this for diagnosis last summer tracking down strange noises. The noises turned out to be a bad exhaust clamp (you can hear it a few times in the video) but I discovered bad engine & trans mounts in the process. Thought some people might find it interesting. You can see the poor little frequency valve wire taking some abuse.

I don't have any after footage, but replacing the mounts made a huge difference. Mainly in the shifter. If you have a 5-speed and feel like the shifter wanders a bit, consider inspecting the mounts. I'll admit to being a little embarrassed when I saw their condition.
