knock knock severe vibration
 

I got an 1983 944 non turbo, with auto trans; 112000 miles; pretty much changed everthing( waterpump, head gasket, oil cooler seals,) the other day, i was at a red light and proceeded to go at green when i heard a knocking noise from directly behind the engine followed by a very severe vibration that increases with RPM. Any one got any insight they could send me? Thanks a bunch in advance...

I hope its just a motor mount. look for fresh oil around the mounts. if thats it relax. no biggie
