Yes, the engine used to have vibrations at idle and that went away - it was a kind of a little "dance" more than vibrations. But note that I did a complete front suspension overhaul, so I can't say with absolute confidence the new mount replacement is what fixed it. The mounts didn't seem to be worn out or leaking though, but you can never trust the appearance of rubber.
