Jay---Before disassembling any further, I'd pull the clevis pin at the
SC connection, and then push the clutch operating arm towards the front
of the car. If the sound you hear lessens or stops, you cound have a
worn throwout bearing dragging on the clutch. If this sound is only
present with the clutch disengaged, then it could still be this t/o
bearing, in later stages of disintegrating.
If the thrust washers are toast, there should be ample play in the
crankshaft, which can be checked by pushing the timing pulley back and
forth.

Somehow my original message got lost in the ether, so I apologize for my
follow-up post that must not have made too much sense. The short story
is that my car has a sound coming from the timing cover area that
alternates between a "bad belt" sound and a true howl.
...The howling sound in particular changes when the clutch is pushed
in....
The sound was still there even after removing the fan and pulley. I
have taken off the timing cover and sump and don't see anything obvious
- some brass sparklies and a small amount of gray sludge (probably from
an old cam that lost a lobe).
Mitch V. responded with a tensioner related howl - very possible as this
is a pretty new tensioner and chain (<500 miles, but a lot of idle time
- didn't make any noise until yesterday). Anything else I should be
looking at? I will probably pull the bearing caps to see how things are
going (I rebuilt this engine 14 years and 30K miles ago), and I will
check the crankshaft end float.
Thanks,
Jay
