I believe that someone else, Karl from Westy Ventures mabye, was saying that
he solved the vibration by welding the left side engine carrier where it
meets the frame.  There is a rubber bushing on the left engine carrier in a
Tiico setup that is not there on the right side carrier, or on either
carrier in a Diesel Vanagon.  He somehow overrode that carrier bushing, and
made a fixed connection to the frame.  No more vibrations.

Again it seems counter intuitive to solve a vibration problem by removing
and/or stiffining the current tiico bushing and mounts.  But it seems there
are at least two account of it working.

Cheers,

Cory
