Okay i've been having this problem for about 2 months now

Under anything more than very light acceleration i hear what i can best describe as like a spitting noise from the engine and a slight drop in power when i hear it. seems to be more prominent when turning a corner,

i was wondering if anyone could shed some light on this,

my mechanic thinks its a dry bearing but hes not sure and he said if it is a dry bearing its not bad enough for his to determine which one.

thanks in advance
