Two in particular concern and/or annoy me though!
The first is a whirring from the torque tube when the clutch is disengaged. This is pretty loud and makes the car sound like some kind of enviromentally friendly electric thing. It becomes more apparent with speed.. :/ I've been advised it may be the thrust bearing or engine-torque tube bearings which makes sense I suppose, but damn if it isn't pissing me off!
The noise has only made itself known since I removed the diff the second time and fitted a Volvo diff-g'box gasket and one of Macs kits for the diff cover. Strange that it should be heard now? I'm wondering if the OEM gasket is too thin maybe? Also, I just remembered, one of the grommets wasn't refitted to the torque tube. I guess some mechanical sound could be escaping, but surely that would be minimal? - I have been reading up on whining torque tubes on a Porsche site and they say tube bearings at fault too.
The second is equally strange but not as annoying (I can make a tune with this one) When travelling at >50/60mph (usually in 5th but I doubt it matters) I can hear a high pitched whistling from the engine. The pitch changes with a touch more revs and add a bit more and it goes completely. To make it disappear you have to press the accelerator a little harder than required though, so the noise always returns as soon as I slow.
My guess is the carb is causing it, as it seems to be related to RPM/air intake. Also, the noise seems to be just behind the bulkhead.
Short of lifting the rear end on axle stands with the engine running and engaging 5th gear I do not know how to spot/solve the problem.
AFAIK there are no loose/split hoses or any damage etc. There is the 'valve' on the inner wing which has something to do with the carb. This was never connected though, I asked about it on here last year and didn't get much info.
Any ideas people?
Much appreciated, Liam.
I much prefered the car withouth this character trait!
