Hello I own a Saturn

After Motor being Installed Back in Car About 2 Weeks of Driving it a Really Loud Knocking Noise Came about Which Was Contious and Got louder as accerated... Can anyone that can help with where the Noise might be Coming From It Sounds Like it Bottom end of Motor .Motor is Back out and on Stand Completely Torn down again . I am Leaning toward Piston Bearing and Crankshaft Bearings ...Thank you !!!
