Just to keep all up to date.
I just finished installing the engine mount onto my 80K boxster.
Here is a .jpg of the one I pulled out. Notice all the daylight. Basically nothing left of the mount. Jake again was correct (again). I'm glad I did this. With the new IMS bearing, water pump, MAF sensor and mount, my vehicle feels more responsive and smoother than ever. IMHO the bearing , clutch, and mount issues may have been robbing hp at my wheels. I also lost the start-up smoking issues I have been experiencing (not sure why). My mileage is also up since I placed the proper air in my tires.
Take a look at the mount at:

P.S. recommend using a deep 15mm socket when removing the mount from the chassis. Also nice to have a cool engine when doing job. I have the burns on my hand and forearm to testify.
