Whats this noise?
 

Here is clip of me revving it in neutral not stepping on the clutch pedal

Don't tell me its TOB without some serious proof lol, its neutral and clutch pedal is not pressed! if i press the clutch pedal the noise goes away.

Any ideas?

Since I can't guess TOB, I'll guess gear rollover ……..;)

Sorry, it's the TOB. Early signs of failure. Mine did that same noise when I hit 60k. My tob when out at 80k. So.... it's better to start saving or thinking about replacing it in a while.

Then again who knows it could be belt or something lose. Who knows.

That's TOB. Mine is doing the same thing at 112k km, and I'm getting ready to replace it soon. Would be worthwhile to upgrade the clutch fork while you're in there too

That is TOB.
Just wait too long and you will have your proof.

Hey @Tcoat, I replied in another thread for this sound from OP; I'll be at the dealership the next 2 days for fuel pump replacement as well as having this noise checked out. Originally thought input shaft but now leaning towards TOB. Since this noise way my original reason for being there, should I just pay for a clutch/TOB replacement while im there?
They told me anything clutch-related is out the window for warranty since 3/36k is up. Noise goes away after warmup so i'm leaving it overnight tomorrow so they can coldstart it and hear the whine. Would TOB do that, and about how much should I expect for a clutch/TOB job?

Also, @PurpleSpaceShip i'll try and update you within the next couple days with what the dealership tells me/whatever I get done. I have the same exact noise under the same conditions as this and the other post. Hopefully its as easy as TOB like tcoat and humfrz say.

Cold start noise that goes away with warm up or pushing the clutch was the very early warning signs that I had. If left it gets much worse until the TOB melts down like in my pictures. If caught early you do not need to have the clutch done since it would not be damaged yet.

OP - that's TOB for sure. TCoat nailed it, I ignored those early warning signs and mine died on track at my last event. Mine had 25K miles on it, but roughly 6k of them were track miles.

And as an aside - if you do wait too long, you get this done to your pressure plate and the aluminum snout over the input shaft that the TOB rides on lol...so budget for a clutch and that cover/snout. And the FSM says the bolts for the cover are one time use. The seven of them are $6 a piece at the dealer...

Dude - I was going to put up pics of my TOB, but yours trumps all - it really did MELT DOWN lol! My TOB carnage cannot compete...and your TOB quill/cover looks totally fragged. Must be more common than I thought on these cars. At least your wear plate hiding the background looks TOASTED as well, so it was clutch time all the same. Mine still had life, but while the thing is apart, might as well swap it. Pulling the trans is not the most fun thing in the world.


Heed the warning OP. TOB is the chant of the "been there, done that R&R" crowd.

Yep. I knew what was happening but waited too long. Went from the whirring noise to a squeak to a scream and then a bang. Took a few months though. Was totally my own fault for procrastinating on the repair.
In my 20 or so MT cars I have only ever had to replace one clutch and it was a 40 year old car. This clutch would have been fine if I had just changed the TOB when the noise started.

Imho it's not that common to these cars, as looks rather generic for TOB, as rather these cars more commonly are abused, clutch & it's TOB included :)

well, no problem bro, because if its TOB its actually an easier fix lol. i hope that turns out to be the problem.


@jfarkas ok bro ill keep an eye for your message thank you for this!

My problem with TOB diagnosis is that i actually have a "new" gearbox. i bought of some guy from facebook. its supposed to be 8k milage 2015 brz gearbox. and i also installed new Exedy OEM replacement clutch kit. if that really is TOB thats making the noise the mechanic must have installed it improperly. idk man.
