Maybe Clutch Problem

Hi everyone,

Needs some opinions about this problem i'm having. I've searched for grinding/squeaking noise when clutch pedal is pressed in and found some interesting topics on dry clutch fork but i don't think it's the same problem I'm trying to describe.

Basically I was driving yesterday along the hume back to sydney for about 5 hours, gave her a 20min breather middle of the trip. My exit is very close to my home and everything was going fine until i geared down to 2nd for the final turn before the home stretch. As i went into 2nd, it sounded like I didn't engage the clutch correctly, not crunching gears sound...but more like...(not that i know how the transmissino works) but sounded as if the clutch cable couldn't get pulled right and was rubbbing against something spinning...

Finally back on the driveway, waiting for garage door to open, clutch in...then just grinding, grinding, let go of clutch pedal...sounds go away.

When i put the clutch in...it takes about 1 second to start grinding and stop immediately once foot is take off.

Going into gears is fine, but when i try to the grinding gets effected... like it grids slightly slower and changes tone abit...and just sounds whatever is grinding its been tried to work just that little bit extra...

Hope i've described it ok...

Called mechanic after reading about the dry clutch forks and described the symptoms to them...they say from what it sounds its a bearing that spins together with the clutch is broken and they'll need to take off the box to inspect.

First reaction was ..f*k...$$$$ not just for labour but it'll be stupid not to upgrade the clutch at the same time..

Mechanic reckons its safe to drive over to inspect..but to be honest its quite embarrasing plus not even sure if it'll damage it more.

PLUS i have to fill up petrol too...arghhh...will have to ride the clutch to get into driveways...it'll be a nightmare of grinding/squealing

Basically i'm asking

1. If anybody here had the problem I'm describing or knows whats going on?

2. It is better option to just tow the car there?

3. What kind of cost labour wise will i be looking at?

...and its a R33 gts-t

thanks everyone.

1. the noise is your throw-out bearing.

2. find a d.i.y thread on how to change your clutch. at the most labour time will be 5 hours for you to do it, you will need a mate to help lift the box out

3. and think by doing it self you'll save some money and learn about your car

p.m me on what your gunna do

cheers matey

Ok cheers guys!!

thanks for all your help, same to those who PM'd also.

It'll most likely get done at a mechanic. Been back to them for quite sometime, hope they'll look after me this time as well.

Hmm..just one thing i need to know, the noise is rather harsh... but I've been told by the mechanic its ok to drive over to them.

What do you guys think? its ok to drive it?

I drove my car to the mechanics just then..just like last time, big grinding noise when clutching in..and found that it squealed a high pitch kind of noise as the clutch is gripping for 1st gear. Even just going down the street and approaching the first corner, each time i clutched in the noise had gotten fainter and fainter. until aobut 2 mins into the drive it completly disappeared.

The noise surfaced just one more time when taking it into the mechanics workshop for the hoist.

But this time, it was only when releasing the clutch pedal, taking off from 1st from a standstill.

No noise what so ever on the way home.

It seemed like its ok once gearbox/clutch has warmed up, will try it out again tomorrow morning.

I didnt want them to drop the gearbox yet, wanted to wait until a new clutch arrives. So i got them to have a look around for anything else.

They checked the gearbox fluid levels and it was fine, nothing else they could find.

But they couldn't really check the amount of lube where the clutch fork goes as mentioned in others threads. (they reckon its abit tricky to check)

Mechanics still believe its the throw-out bearing but could not really justify why the noise has dissappeared.

They said if the noise comes back, I should bring it in and they will drop the box and have a look around.

If it the throw-out bearing...is it normal for the noises to go away once its warmed up?

If the noise does come back next time i check...I'll order a new clutch...

but what bearings would i need? not sure what comes with a clutch kit.

Is throw-out bearing another name for the Thrust bearing? or is the Spigot bearing?

Barney2010 - Yea you were totally right. Got a new clutch and noise has gone!!! Thanks for everyones input.

the mechanics forgot to swap over the spigot bush i bought tho...they didn't know I supplied one but apparently the spigot was ok so they didn't raise the issue. =/

got another problem now, the clutch is only just disengaging. its right to the floor.

will have a look around the forum, will prolli start a new thread if i can't find it, but feel free to post your inputs if you wish.

Clutch fluid has been bleed so much and pedal is still way down...if I release the pedal just even 3-5mm I start moving.

Makes gear changes slower, something i don't think i'll ever get used to (before i could get out of gear half way down, and release clutch as I'm gearing up)

A new slave cylinder has been put in, (the old one was leaking)

A longer slave rod has been put in. The master cylinder rod has been adjusted as much as possible already.

Mechanic say there is no more air in the system, I was waiting and waiting, took them about 2 hours to bleed it.

They believe the flywheel has been machined down so much and is causing the really low clutch point.

Washers were not installed under the pivot thing, and I'm not about to pay another load of labour for gearbox removal.

Is there anything else you guys can think of?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
