Way too little information regarding the sound. At least try to figure out the general area where it is coming from. Also, does it go away or changes tone with RPMs? Etc. etc.

Its coming from the back of the engine (cylinders 5 or 6 ) in that area.. When I put high rpms it does go away but yew could still kind of hear it also when the car has been driving for a while like 20 min or so the sound goes away a little
