Bad Motor Mount?

Bad Motor Mount?
Here you can see my 2003 Mini being revved by sort of 'kicking' the gas. I'm trying to demonstrate the way that the engine is vibrating, and would like to know if you think the Front Mount is bad. The dog bone and trans mount have already been replaced. I'm getting a wobble or shimmy during acceleration above 40mph, and curious if it could be this front mount. The vibration felt while doing this is the same that is felt while driving, only while driving it only occurs above 40mph. This was in first gear on jack stands.

that mount is oil filled and a weak spot ... they leak ....
from the MINI MANIA description of the part:
Engine mounts allow an engine to move and absorbs most of the vibration for a smooth ride. Unfortunately, these engine mounts deteriorate over time and begins to transmit vibration into the cabin. Loose engine mounts can also affect performance by sapping the off-the-line performance.
The hydraulic engine mounts also tend to leak over time therefore reducing it's effectiveness. If you find some oily fluid residue around the hydraulic mount, it's time for a replacement!

there are solid mounts and upgrades available

Me, I would change both the upper passenger side mount and the mount under the engine. Assuming your 03 has the same "dogbone" type mount for the bottom that we have.
Also on the upper, I am thinking your mount has a strut like arm that travels back to the shock tower and is bolted in there as well. Double check that bolt. There is a mount for the trannie on the driver side but I am not aware of how that is fabricated on the early Gen1s.

comment from WAY if you pull up all I linked ....
"02-04 Passenger side Engine mount for R50 R53 MINI Cooper and MINI Cooper S. As these wear out they tend to get shorter. When this happens they put extra stress on the upper and lower motor mounts. Replace it early otherwise you'll be buying all three and causing extra engine and clutch wear. As most people don't know this mount is also hydraulic filled, even though it just looks to be solid rubber. These do sometime leak so also check that"

When I swapped my head, the mount looked fine on the outside. As soon as I cracked the bolt I got covered with some brown fluid. Could totally be shot. I wouldn't think an engine mount would cause a vibration on accel >40mph though. That doesn't make sense at all. But hey, stranger things...
