What the hell is this noise and should i be worried?

[Mook]

Ive owned the Evo since October and since day one ive been concerned with the trans...it already has an aftermarket cluch in it (we're assuming exedy due to the purple casing but thats not a sure thing) and i already had it to mitsu once to work on the transfer case but they said everything else trans wise looked good (but u cant trust them anyway).

pretty much since i bought this ive had this noise (heard in vid below) that only comes on when i'm engaging the clutch and its basically at the friction point. i always thought it was audible inside but apparently its very audible outside as well....the trans under normal driving is a total bitch. its either smooth as hell (rarely) or hard to get into gear (tho thats mostly when i'm downshifting). i'm not exactly sure what this noise is...if its normal...if its not...if i should be worried....dunno...thoughts?

Aint normal, sounds like you are having some heavy friction going on, Is it an exposed clutch or do you have it covered? Might want to take the cover off and see if anything comes out, even heavy dust.

Where do you take it? BIGGERS? they arent that bad there, actually decent dealerships on 19

 

[Mook]

yea i took it to biggers when i first bought it...good guys

 

[WhiteDevil]

They got good service there as well. is it still under warranty or does that get nix'd when you install the proper shit that the factory didnt?

 

[Mook]

it would be over mileage warranty anyway....i was dumb and bought the car premodded...slightly regret it right now

I do know a good tranny guy on 31 in south elgin, his name is Tommy Kasper, owns A-1 Automotive, does alot of tranny's and is a gearhead himself.

if you do go there, ask to see his baby thats parked in the container in the back. Itll blow your mind, that or his drag boat.

that is not a normal noise.

 

[Lord Tin Foilhat]

yep id get that shit checked asap

 

[Mickey]

Does that noise happen only in neutral or does it happen any time you engage the clutch?

 

[Mook]

engage

 

[James]

That is nasty.

To help narrow it down....it's only evident during clutch "engagement" right.
So when the clutch is fully disengaged and fully engaged it's gone completely, right?

If yes to above...it's 100% the throwout bearing and/or a bent finger on the pressure plate.

It would be very bad if that was a driveshaft or lack of fluids....but let's not get ahead of ourselves.

 

[Mook]

fluids were changed recently so i'm 100% it cant be that....i take that back...99.9% since nothing is 100% in this world

 

[Mickey]

I believe that noise comes from trying to feather such a beefy ass clutch. You sould ask someone else who has an evo with the same clutch. My buddy who had an ls1 trans am had the same noise from clutch engagement. The whole car used to chatter.

You didn't answer my questions.

[Mook]

yes..only when its at the friction point/engagement

Wouldn't the throw out bearing make a noise any time it was disengaging the clutch if that was the problem? I think were not looking at a throw out bearing.

mook- When you have the pedal depressed does it make the noise all the time?

 

[Mickey]

I don't think its the throw out bearing and its definitely not the pressure plate. That would be too noisy with the clutch disengaged. But what do i know, I'm not a DSM guy really.

I take that back, its not the fingers on the pressure plate.

 

[Mook]

clutch pressed all the way in, no noise...clutch pedal all the way out, no noise...clutch let out to engagment, noise....

 

[Mickey]

Hmm, I did a search on google and found an upgrade. The clutch release rod tends to bend when using exedy clutches(obviously because of higher pound pressure plates). That might be your issue the clutch may not engage/ disengage all the way. Check it out. http://evomoto.com/product_info.php?cPath=3&products_id=279&osCsid=a29e9baf432afcd014cb8a2962ca5769

Alright look Chico.

When a clutch is "engaging" the ONLY things coming into contact are the pressure plate and throwout bearing.

Once they are fully seated together (or not together) there is no movement (or possible friction).

It's not rocket science.

 

[Mickey]

First of all we don't need u to try to make us feel like idiots. I know what I'm talking about.

He is complaining of a problem when the cutch is at its release point he hears a noise. NOT when he has his clutch foot to the floor. when his clutch foot is to the floor the throw out bearing pushes on the fingers of the pressure plate, releasing the clutch and trans from spinning with the motor.

BTW when the clutch is engaging the the clutch is coming into contact with the pressure plate and flywheel so wtf are u talking about?

 

[Mickey]

Fuck it. I'll argue tomorrow. I'm crashin' bishes.

could be throwout bearing but i dont think so. i think the clutch you have is just not a stock upgrade or stage 1. id be willing to bet its more like a stage 2 or 3 or more which is going to have "chatter" or noise during engagement. i wouldnt worry too much

or it did the same thing my old act in the honda did and the clutch disc ate a quarter inch out of the pressure plate face

Thats what I thought too. I have expirienced clutch chatter before but a buddy of mine said it could be a hard spot in the clutch disc lining (like a hard spot in brake pads that cause a squeal). I think thats entirely possible but if you took it to a shop they would probably want to drop the trans to see whats going on anyway, in which case they could visually see what the hell was going on.
