One of our customers at Helming’s Auto Repair wanted to see the ramifications of bad motor mounts, so we made a video of his car, a Honda Odyssey, and showed him. You can see the engine jumping up a little bit. When it gets worse you can do a lot more damage.
(Car starting, engine revving, radio in background is unintelligible)
So there’s the engine just rising up a little bit when he revs it, that’s because the motor mounts are bad.
