Today i regonized.
Comes on Idle, Park if you turn steering top right or left or D at idle randomly or turning wheel same time its most bad.
So when engine is idle = low rpm and under "load" for same time, noise comes.
If you rev engine etc nothing abnormal.
I have been main bearing problem in olds 307 and piston slap but different sound.
Idle on D position
Idle on D position, steering wheel turning at same time
Please help! Video is robust but voice is very realistic.
And im pretty sure that noise is coming to passenger side or center, not drivers side.
