Rattling When Revs Drop

[Dylan454]

Ok first, yes I have had a search. There are lots of threads about clutch/gearbox noises. But that none similar to my problem.

1990 r32 gtst

FMIC

Stainless turbo back

Coil overs

Xtreme heavy duty single plate clutch

Now the clutch is about a year old say 15000 km, the problem I have is that when I'm in first gear or reverse doesn't matter. If the revs drop low, while moving slowly like taking off, I get a loud metallic rattling.

The cutch feels fine and so does the gearbox, it doesn't make this noise any other times except taking off very slowly when the revs drop low.

I don't trash my car, no burnouts or launches mostly just taking corners fast.

It's not a major problem as the car still drives fine it's just annoying. What do you guys think it could be. I reckon a finger on the pressure plate may have Broken.

Loose springs in the clutch centre.

could be actually, can they fall out and damage things.

[GTSBoy]

They could fall out if they were completely wrong**. But usually they're just loose enough to not be completely captive. One or two have pressure on, one or two have none, and you get the rattle.

** really not going to happen.

ok Im not really to worried as it just happened one day and it hasn't gotten worse. so I guess she'll be right lol

[Dylan454]

so I have found the source of the rattle. it was the stone/heatsheild on the cat, I must not have put it on properly because it was loose and would rattle when the motor would shake.

I have a similar problem at the moment. The baffling in my muffler is loose and rattles

[GTSBoy]

I suppose that was the other possibility!

[iruvyouskyrine]

I was going to say heat shield on the steering rack had come loose and would be rattling haha. I was close.
