This is weird....what is this noise?

Hope someone might be able to guide me in the right direction:
1993 Honda Civic...had noise in clutch...when I push the clutch, it had
a classic "release bearing" noise" except the weird thing is...the
noise happens when I DEPRESS the clutch pedal, NOT release it....I took
out the tranny, and changed the release bearing...the old one was
obviously bad, sounded like an old roller skate when I spun it, and had
play...I thought for sure that was the problem. When I put it all back
together...EXACTLY the same noise!
Here's the weird part: the noise is ONLY there when the pedal is
depressed in NEUTRAL...no other gears. The only other time you hear is
is while coasting in 1st gear, but not if I depress the pedal in 1st or
any other gear. If I am stopped and idling in any gear with the pedal
depressed there is NO NOISE, if I move the shifter into neutral, the
noise starts...
ANY SUGGESTIONS? Help would be greatly appreciated. Could it be Pilot
bearing? or internal tranny problem?
Thanks

 

The proper way to test a throwout bearing is to press on it, in the same
direction as when the clutch is depressed, and then turn it. If you don't
load them up a little bit, they will appear loose and can make noise. Pilot
bearings are pretty cheap. Internal transmission problems are almost always
expensive. I am thinking maybe pilot bearing.

Probably input shaft bearing. My '83 has a similar noise and I just
turn up the radio a bit...

Did you change the MTF while you were under there? It's probably the
tranny, and a fresh bath of MTF might be the cheapest way of finding
out.

Why didn't you replace the pilot bearing when you replaced the TO
bearing?

The MT in my '97 civic was making all kinds of strange noises at all
different times. It also jerked quite a bit when starting in first and
even a little in second. When I pulled it apart it turns out the pilot
bearing was installed incorrectly which in turn jacked up the input
shaft bearing. I ended up putting in a used tranny and it was like
driving a brand new car.

 

Grumpy got it right.
