Does the sound get louder the longer the car is running or the warmer the car gets or does the sound go away? Is it there throughout the RPM band? Does the sound go away when the clutch is pushed in?
I drove my V6 firebird around with 2 spun bearings for about 12,000 miles or so before I was ready to do my motor swap. I put 3 qts of 20W50 and 2 qts of Lucas oil stabalizer. The knocking went away. I also broke a piston on another 3.8 motor and it sounded the same as when I spun the bearings but when I did my 20W50/Lucas oil trick it didnt help in making the knocking not as loud..
