A minor update on Rusty...

I have learned that the engine torque damper can cause cracks in the firewall if it seizes. Thankfully mine has not seized, but the bushes are shot having cracked and a few bits have fallen out. It is important that the damper be functional or you will end up needing to weld your firewall. I have seen some photos of such cracks on the Jensen Owner's Club site.

After some research and a few dead ends, you have some options if yours has seized: 
  1. Remove it and live without one - supposedly no issues arise doing this although the owners who have done it also state that they replaced the Jensen motor mounts with Land Rover Discovery mounts which are much more stout.
  2. Replace it with an aftermarket unit such as the Stabilus 73DR52J unit. I have not tried this, but my research says that this is a functional, compatible equivalent. Martin Robey says the original damper is NLA, so you can't just pop in a new unit.
  3. Get yours freed up, and if it still damps, you can replace any damaged bushings as I have with a set of urethane bushings.
I used a vise to press in the new bushings, and reused my existing sleeves. You must cut the bushings to length as they are a generic set. The part number is shown in the photo, but may be hard to read. Energy suspension 9.9176G.

Cheers,

Vance
