Massive Grinding Noise, Thrust Bearing?

[turbo_brian]

Ok, car started to make a strange noise, not a bearing grinding noise like a big end, but a constant rubbing noise.

When driving, it sounds like the whining you hear with the european super-touring cars (if you have heard it), where th whine gets higher and higher pitched as you get faster and faster.

When idling, it's loud enough to distinguise, but when you clutch in, the noise vanishes and you hear the yummy rumble of the Godzilla motor.

I did a gearbox flush prior to the noise becoming LOUD (note: the noise was there before the flush) and there was no sign of anything out of the ordinary, no large quantities of metal filings (a small amount), and the oil was actually quite clean and consitant.

I am thinking it's a thrust beaing that's given up, and it's time to upgrade the clutch and fit a new thrusty, but want other people's opinions before I bark my orders to the mechanic.

Car is an October 91 R32 GTR Skyline, 100,003kms on the clock, engine previously rebuilt, clutch replaced at some stage, but unsure when.

Thanks in advance people.

Sounds like Thrust bearing to me! Mine was on the way out, too and it made that exact sound when the clutch was out.

Also, my Master and Slave clutch cylinders were leaking! You might want to check them, too.

well i have the exact same noise.

i had the clutch, thrust beaing and spigot bush changed 5000ks ago so i really doubt its the thrust bearing!

im thinking that its the input shaft, new Gearbox time i think!

or rebuild time, cheaper and still effective...
