Rusty,
My first cut at mounting the evap cores was also to
the engine. They did exhibit a lot of vibration as
they were securely mounted. This vibration was enough
to scare me into changing the mounting to the engine
mount instead. It doesn't take a blown rotor to make
the engine run rough. A fouled plug(s) can effectively
make it a single rotor engine. While a fouled plug is
not a catastrophic failure, loss of cooling could be.
My cores are now mounted in a sheet alum frame with
2"wide 1/8"thick self adhesive rubber foam tape(from
Home Depot) between the frame and core. They are
mounted to the engine mount with 1/4" rod between
plates on top & brackets on the bottom.
Already sent you a photo(funny looking firewall).
Hope this helps,

>OK, there are a number of you out there that have
cores mounted to the engine.  Do you have them solidly
mounted, or are they on an effective cushion of some
type?  Can you post some pics?  Has vibration been an
issue with any of your mounting methods?
