my damper setup is erm not standard anymore

i have a bailey damper and thats connected to the turbo via a bracket that i had to have made up. i got the exhuast set up a while ago and the vibiration went but after a few ays came back.. not sure what it could be. is there anyway i can check the engine mounts?
