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,
Jim Maher

>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?
