diesel Vanagon engine mounts allow quite a bit of engine rotation with
torque application.   If you have ever seen the motor being revved,
standing right there and looking into the engine bay, you will see what I
mean...

  Far be it from certain that I might guess exactly what  those German
engineers had in mind, for certain, when I try to suss-out why they did a
particular thing....German auto designers are sometimes on a different
planet, in my book...Whatever the reason, the exhaust mounts they put in
the diesel vanagons do work well for the diesel motor and if carefully
installed, they seem to work well on Gas inline conversions, too.

   I had mine hung from the frame, for a year,  on rubbers, something like
the FAST newest 'plan'...but it was still transmitting lots of noise into
the chassis and I really didn't like seeing the end of the tailpipe stay
still when the motor rotated...Mine didn't break, hung from rubbers...but
it works better now mounted with the diesel exhaust brackets..
