the car is an 87 TII with about 600miles on a rebuilt engine.

The clutch I used is the same one that was on there when I rebuilt it because I was too broke to replace it at the time. It was fine before and after, but in the past 100 miles it has started to make noise. at first it was only when you pushed the throttle over half, but now the noise is much louder and nastier and it happens at idle!

I already ordered a new Exedy stage 2 from spooledupracing, so replacement has been taken care of. I also just replaced the master and slave cylinder, which didn't affect the noise at all.

my question is: why is my clutch making this noise? could endplay cause this to happen? is it because I reused an old clutch but replaced the flywheel?

you can hear when the clutch is engaged and when it isn't, its much nastier in real life.

Uh..... that sounds BAD. I don't imagine how a clutch could make that sound.......

lol, no kidding, and it gets worse every time I drive it, Luckily I only have to drive it to work ONE more time before I can do a clutch job... time to start praying.

If my car made that noise.. It would be parked, jacked up, and inspected THOROUGHLY before driving it again. That sound is the sound of damage being done, I can almost guarantee it.

probobly, but Theres not much I can do about it.

on the other hand, it doesn't make noise in gear unless you give it some gas, which I do not give it. and strangely the noise almost completely goes away after I drive it for a few minutes.

that doesn't sound like something i would want to rise around in. doesn't sound safe at all. make sure you tell us what it was when you take it apart....

you sure someone wasn't playing a snare in the garage??? jeez.

don't drive that thing 'til it's fixed

SureShot

Hung starter pinion?

Clutch parts or tools or bolts loose in the bell housing?

The more you run it, the worse the damage..

Luckily I was able to get a ride to and from work today, so I didn't have to drive her.

It couldn't be a bolt or something, because it is directly controlled by the clutch, and the noise gets better as you drive, but much worse if you give it gas.

the only thing I came up with was maybe the clutch disk and the PP are hitting due to irregular wear or something weird like that.

I will be pulling the trans in a few days so I'll let you guys know what I find

badly Warped flywheel??? maybe??

pressure plate springs...

I was thinking a piece of the clutch broke...or the center spine is fractured. That would explain sloppyness at idle but driving allows it to allign itself....too much gas and it starts to seperate.

let me know when you yank it if you clutch disk is fractured.

ok, I finally got around to uploading some pics of the clutch itself. The surprising thing is, it looks fine!

the only thing that i see is that the wear is only in a ring in the middle, which is strange. its difficult to see in the pics, but the middle part of the disk is worn more than the inner and outer edges. same with the PP. the flywheel was brand new, and it now has a few blue-ish marks on it, like burning or something, but you can't feel them with your hand.







anybody have a clue as to what caused the irregular wear?

also the PP is really rusty for some reason, is that normal?

micah

there is a certain degree of break-in on these clutches before they wear evenly.

Sounds like it was getting super hot.... maybe your clutch disk is glazed over from age? Just put your new clutch on it and call it good.. Replace EVERYTHING... and you'll want to get your flywheel resurfaced again lightly just to be sure. Atleast.. I would.

Was it rusty when you put the engine in before? I blame it on you not living on the west coast.

as far as break-in, the clutch had almost 500 miles of easy going and then it started to take a **** for no apparent reason. god knows how many miles were on it before I removed it the first time.

ya, the blue marks on the flywheel look like they were caused by heat, but since the material looks fine and it was only used for 500 easy-going miles, I'm not concerned about getting it resurfaced. I already have a new clutch kit, and am in the process of removing the pilot bearing so everything clutch-related is being replaced.

it was a little rusty when I removed it, but it somehow managed to get a lot worse while it was in the car (I installed it in late june again). I dunno what thats all about, I just figured I'd throw that out there. and its summer right now, so why would it rust so much more during the summer? I drove the car almost every day...

Rust could be from handling it without cleaning it. The contaminants in your skin can rust metal.

Tenz

possibly but to that extent?

unless you where molesting it; i'd rule that out but i could be wrong.

There's no way that noise came from that clutch. Something else is very wrong.

iTrader: (7)

Yeah, handling it without cleaning will leave small surface rust about the size of a finger or hand print. That looks more like surface rust from a badly prepared/old metal surface (similar to an old exhaust manifold for example.)

1RevvinFC3S

^True. You're probably right on that one.

Well I think I figured out what was wrong...

when I went to install the new clutch (FINALLY got the goddamn pilot bearing out after about 4 days with a grinder, a screwdriver, a hammer, and a pair of needle-nosed pliers) I noticed that the flywheel was loose! the 6 bolts holding it on could be turned with a wrench with one finger. admittedly not THAT loose, but still, I think that was the problem all along. So this time I reinstalled the flywheel and the clutch with lock-tight.

wish me luck!

So the flywheel was loose? Id take it to a machine shop pronto... you sure it isnt warped?

Osirus9

warped? could it really be that my flywheel got warped and that was the cause of the noise? Its brand new! or was it just because it was jiggling around? keep in mind its only been 500 miles! and this noise has only been for the last 70 or so...
