maybe a useless reply assuming you put all back as it was, but ... i had motor related vibration that was found to be few missing bolts from top of tranny-motor connection 8-O ;-)

also, news to me from these forums and checking my haynes book, there is a vibration damper on outside front of motor down behind lower crankshaft pully and timing chain cover ... could something be wrong here ? ... but like blazerlt said, check the easy stuff 1st.
