changing clutch

[DaveyB]

Sorry in advance if you done the clutch problem to death, but I need some reassurance or otherwise on the state of mine.

With the weather being bad and many roads shut due to flooding, I have been stuck in heavy traffic ques on an alternative route to work for last two days. So engine temp has gone up,well about an extra 2mm past the zero on the gauge, and obviously lower than normal tickover oil pressure (just less than 2 on the gauge).

Alright, alright I'll get to the point. My clutch feels alot softer than usual, and doesnt have the same feel. Is it possible I could have cooked it, got oil on it due to leak etc? And how can I test it?

I am worried as I'm taking the misses to Bath for the weekend and that will be 300 mile round trip.[]

Does it slip? When warm, and you have the opportunity, give it some heavy throlltle in 3rd or 4th gear from about 2000rpm. The revs should increase in proportion to the speed.

Usually the pedal gets firmer as the clutch wears. No idea why, as it doesn't seem logical, but that's what most people report.

Hi, after hitting heavey traffic again this morning for 45mins, I managed to get on to the A14, and on the slip in second I accelerated. The revs went up and the car didn't get any faster, and it did it in all gears unless driven extremely gently. So the clutch is defo slipping.

But as I said before the pedal doesn't feel right. The upper part of travel seems awfully light. And to confirm my suscpicions that all was not down to purely the clutch plates worn (I could be wrong though). When I parked up at work, the clutch pedal stayed down? It could be a sticky mechanism. Any info on the linkage would be handy, and any advice on what to check before I fork out on a garage.

If I'm not mistaken David, the clutch is hydraulically actuated.

I'd look at that first (master and slave cylinders, leaks, etc) and the pedal mechanism before taking any drastic action regarding the clutch.

No doubt Richard H will be along soon to give you more detailed advice.

Yes, I was thinking of going around all the 'clutch like' moving parts with some WD40. And then I'll need to identify which is the clutch resevoir etc.

Cheers

when my clutch neede changing it was really soft, I thought it was the turbos that were hydraulic and got lighter when worn.

See this post I did last year.

Yours sounds very similar.

 

[DaveyB]

Hi watlina,

It certainly sounds similar. I think I'll need to get it shipped off to the garage. Just out of interest who did you use? I'm near St Ives, and I would like to get the RMS done at the same time, as well as a check over of the IMS. My RMS is weeping but has left nothing on the garage floor.


Thanks for the help.

David

The last few years it's been to TWG in Peterborough

It'll be in for a service in January. It will be 9 years old on the 12th Jan and I'll have had it 7 and half years. Just coming up on 50k. How time flys

I think most cars has a hydraulic clutch but the turbo has got an additional booster. ;-)

David,

Would be a 'no brainer' not to get RMS/IMS seals replaced whilst gearbox out...... there are 7 bolts that need replacing too as oil can seep past them as was the case with mine....

seals are only a few quid

Thanks for all the help guys. I
Do seem to have had more problems than I did with my s1 Elise!!!

So the car is booked in at Porsche. They were the nearest, and have done a reduced hourly rate. I am having the clutch replaced, the RMS replaced, and they have suggested the IMS SEALS replaced. So, asked why the seals replaced and not the bearing. I am sure the regulars know but I didn't..

Porsche do not recognise the bering as an issue. And if it goes they replace case halves. Straight from the service managers mouth. Already they have added a hours rate to the job, after the price was agreed. Apparently to confirm the source of the leak ( the reason I asked for the RMS to be replaced) they run the engine without the gearbox and apply talc around the bearings..What I don't understand is why am I paying extra for this if this part of the procedure?

So hopefully (fingers crossed) I'll get the car back tomorrow, ready for next years 50 celebrations, without any dramas. They also mentioned water leak tell tales from the head, but I'll worry about that when the bank account recovers.

I did get a bonus, I nicked two sachets of Porsche sugar! And the wifes telling me to sell it!

 

[AlexBell]

That's interesting!

At least now you will have some sort of guarantee on it? IMS I mean...

 

[Magic919]

The RMS replacement procedure is certainly what they have to do in order to get the Porsche warranty to pay out. Not sure why there is a need n this case.

I would add, oil leak diagnosis on these is not a perfect science. I've been told one thing initially and then the final job was something different.

I've had RMS on one car at Porsche and an Indy did the LN Engineering IMS bearing upgrade in the other.

Got the car back. I cannot believe how light the clutch is. It's easier than the Touran. The car is so easy to drive now. And the oil leak was coming from ther IMS seals apparently. And they said the clutch kit was cheaper than first thought, so the bill was less than first quoted. But...

I assume some electric sockets were disconnected when the Gearbox was removed. When turing ther lights on the dash display did not light up. Had to turn them on and off a few times before it lit up. It did the same thing once more. Hopefully thats it for it for now.
