Hello,
I contacted Hartech, an independent UK Porsche specialist who rebuilds watercooled boxer engines. (BTW, they also have a very interesting buyers guide on
www.hartech.org).
Since my boxster has the common RMS leak (but not bad up to now), the gearbox has to come off anyway. I asked Hartech if they think some preventive action can be taken concerning the IMS. They suggest to change the IMS bearing and fit a newer spindle design in the proces. They can do the job without removing the engine or the IMS.
My car has only 35.000 miles, but they suggest these IMS bearings suffer from heat (closed bearings), so replacing the bearing is usefull).
