My point is, i was going by what you decribed....and by what you described it was very close to the description of a spun bearing (as i ahve had one and so have many of the people i know)
Given that, my information was correct, but i also failed to mention that it could be other things (as not completly thinking stright since i was at work).
Give new information, i would research this site and peoples responses very carfully and would take the time to properly diagnose your situation and then come to a conclusion.
Check your:
Water pump
motor mounts
suspension
Clutch (yes it is possible that it maybe bad,even though its new)
and then fianly your engine (cams, rods)
i understand the the engine part is difficult, but if you eliminate the others, you have one conclusion left...or atleast one.
