engine bucks on mounts?

Hi,

I noticed something weird the other day on my 8g I4. When shifted from
park into forward or reverse, the whole engine block bucks forward and back
maybe half an inch on the mounts. I've never seen a car do that before.

I didn't find any evidence of mount wear, so maybe it's normal, but it's a little alarming to look at. https://www.thegalantcenter.org/styl...ault/smile.gif
