vr v6 commodore sedan
hi all,
the other day my trusty sedan developed a rattly noise in the engine bay.
Sounded like its coming from water pump area at idle when at highway speed it
does not seem noticeable. Am trying to fix myself so did a bit of homework and
ended up putting a new tensioner pulley on- no fix, new water pump-no fix,
new alternator- no fix. Am thinking of 3 areas now timing chain, power steering pump
or a friend suggested harmonic balancer. anyway I take the serpentine belt off and noise gose away
put it back on noise comes back. when I turn the power steering pump pulley by hand from 10 o'clock
to 2 o'clock I can feel and hear a slight ticking . when the belt is on and I turn the steering the sound
seems to increase but sond still seems to be coming from timing area.
Im in a quandry and hope someone has had a similar experience and can help me

thanks in advance
