I changed torque converters and the noise is the same. I never took off the flexplate either.I had the intake welded once before but it must have cracked right through. Someone suggested that I should unbolt the torque converter. I'll give that a check and while I have the dust cover off I'll give a close inspection of the flex plate, when I had the motor out I looked at the teeth but not the whole flex plate. Also I remember someone telling me to check the starter to see if the gear is hanging out and hitting the flex plate
