Crunching noise at ~1400-1600rpm in any gear

Hey guys,

Just noticed a kind of crunchy noise coming from the engine bay at around 1500rpm and can feel it through the clutch pedal. It's not very loud and you can't hear it if your stereo is at normal volume. It only happens when the car is in gear but if it's above and below that rpm range it goes away. I tried it with up to 4th gear and it can be reproduced every time.

Any ideas?

Just an update in case some people experience the same issues in the future...

The third place I took the car to was Unique Auto Sports in Seven Hills. We took it for a spin and they are very confident that it's chatter noise caused by the flywheel. They couldn't give me an exact price since they'd have to take things apart to confirm their suspicions.

As a rough guide they did mention that for an S15, a new flywheel is around $1500.

I was just wondering if it's indeed the flywheel that needs replacing...how much $$ is it to replace including labour? I just don't want to get ripped off.

Cheers.

Strange

While I have every faith that UAS know exactly what they're on about, a flywheel is not something that generally comes loose & causes noises... its more likely the clutch assembly. Well I guess you'll see when the box comes out

Indeed. It just seems a bit excessive (the $1500 that is). You can get whole new clutch kits for less than half of that it seems?

Keep in mind, UAS will only ever use genuine Mitsubishi parts

Hi Funkysmurf, did you get a result on this? My manual GPX does exactly the same thing. My local quality garage suggested a gearbox bearing, however after trawling the FTO forums on the web this problem seems quite common on the manual FTO. The general consensous seems to be that it is the clutch.

Hey. I got my fto a few days ago and only yesterday this noise started!! Had an racq check which didnt pick this up at alll. Doesn't occur all the time though. Please let us know what your outcome was???

1500$ what a joke!
u can get your flywheel repaired for maybe 100 - 200 $ depending what needs done. could be a spring or something simple.
wow i really cant stand pricks that try and screw us over just cause our cars are from japan. makes no diference what car it is.
id take your car else where dude. what a raught,

heres how much they are raught these guys sounds like
to purchase. a brand new genuine mitsubishi flywheel is $450
theyr want to charge you 1000$ for labour .
absolute joke. im so disgusted.
it took me 2hours to take it out. maybe 1 hour max for a mechanic who knows what theyr doing.
but in other words. maximimum . no more than 4-6hours labour it should take. to get the job done if indeed its just the flywheel drive your car to newcastle if its possible. defintelty wont be payin that much

he said the $1500 was for the s15s flywheel not an Ftos... no idea what the difference is though.

I had some minor groaning awhile ago at ~1500 rpm. when it was at RPW getting some things done to the gearbox they found a bearing and replaced it and its been quieter since (at 1500)... no more groaning. it wasnt reaaally a crunching noise though... not like when you dont have enough oil in the gearbox or clutch to get it into gear properly

this noise started with me 3months ago car fukd up 1 week ago it was the thrust bearing (part of the clutch assembly) and the input drive shaft where the thrust bearing slides on.if you change your clutch order the inpur drive shaft from mitsubishi costs $22 and then youll be right.

Hey guys. Sorry about the late reply...didn't have a computer for a couple of weeks.

I took the car to a gearbox specialist and they said that it's not a problem as such other than being an annoyance if the sound bothers you (as long as it doesn't get worse/louder over time). They believe the noise is caused by the clutch. They also said that it should be nowhere near $1500 to replace (to be fair, that price was for an S15 flywheel not an fto clutch). After that I took it back to the dealer. They will replace the clutch under warranty if it indeed gets worse in the coming weeks.

At the moment I'm not willing to fork out $$ for a new clutch and I have it covered under warranty for nearly 2yrs still, so I'll wait and see how it goes.

Interesting; thanks for the update.
I think i'm getting this noise too, so I"ll be really interested to see how it goes for you.

Cheers!
