Vibration dampers do fail on these but the noise will stop momentarily when you accelerate, and rod bearing noise will increase with engine speed, but go lightly if it is a rd you don't want it coming loose and fly through the engine block.

Sounds like your engine may be nearing it's life. As a last resort, checkout Wynn's Engine Restore and an Oil Treatment as additives. Sometimes they work, sometimes they don't. In the long run, you will need to have your engine rebuilt or replaced.

get a broom handle or a long screw driver and put it up to your ear and then place the other end on the oil pan...front crank area...isolate the noise before you start to freak out...
