Re: Name that I-5 noise!

My .02 say Power Steering pump. Try loosening belt slightly to see if the
noise changes or subsides.

-------------------------------------
My 87 4KCSQ seems to be warbling, I guess you could call it that. The noise
is coming from the
front of the motor and seems loudest around just above idle. It is
accompanied by a very slight
whistling sound. The noise really drops off above/below @ 1000 rpm.

I have VERY recently changed the following (although it made the noise
before I did)

timing belt
water pump
tensioner (idler) pulley
cam and crank seals
oil pump gasket

I followed the Bentley and torqued every thing to spec, the timing belt can
be twisted 90
degrees per the manual etc....

It sounds to me like its coming from the water pump or the thermostat
housing. Could it be air
in the cooling system? The car runs fine and does not overheat.

Any thoughts??

TIA
