I suppose there is nothing worse than trying to discribe a sound, but
maybe someone will have the patients and knowledge to help. I have a
'92 K1500 siverado 4x4 5.7L (350) with a STANDARD 5 speed
transmission. The engine and cluth and fly gear were changed out for
new just about 3,000 miles ago. The truck has started to emit a high
pitched squeel or scree when the clutch pedal is released from the
down position. It is not the sound of gringing gears, but rather more
like the sound of a small amount of brake dust. It's really not very
loud. It does not happen if I'm sitting in neutral and pumpining the
clutch. It happens in first alot, and sometimes in second or third,
but not when downshifting (which I rarely do, so this could just be
chance). It happens whether or not the 4 wheel drive is engaged. It
doesn't always happen (but does most of the time now), and seems to be
related to how fast the clutch is engaged. If the pedal is raised
slower than normal (I am not hot footed by any means) it does not
happen as often.
Any ideas on things to check? I didn't put the engine in myself (and
couldn't if I had wanted to). The shop who did may or may not be
helpfull. I wish I'd had the work done by Goodwrench (it's one of
their long blocks). All other parts were genuine as well. I'll have
to take this in, but was hoping for some input on what I might expect.
I'm new to the area and don't have a mechanic I really know. I'm
hesitant about the shop that put it in, because they chnaged out the
exhaust system when I first stated having problems, swearing they'd
done a leak down etc, and it turned out the problem was really a
cracked head. They put reconditioned heads in that were bad (they
didn't figure that out, but I did when it ran like crap and blew blue
smoke on startup) and then claimed two cylinders were out of round.
That's when I opted for the new engine. Mistakes can happen, but that
doesn't seem like a good record to me.
Thanks for any help.
