Just need help pinning down a problem I'm having. Ofter the last 2 months my car has gotten a rattle and I suspect its the clutch. it might be best if I make a list of things that might help.

. Firstly on a cold start its silent as stock with no rattles. I can drive it a little harder then normal and its fine.
. The car drives normally as far as I can tell. it always feel very light and I baby the car so I've never dumped the clutch so I cant say if the disc is slipping. However it is louder when being driven a little harder say pulling out of a junction onto a fast road or the start, stop motions of traffic.
. the rattle is almost like a plate wobbling just after its hit the floor and its not a consistent ping it will from time to time stop for a few seconds and can miss a beat.
. When the car has stopped but is still worm in neutral the rattle can only be heard if the clutch is engaged. If I put my foot down and disengage the clutch its silent.
. when my foot is off the clutch altogether I can barely if ever hear it regardless of acceleration or deceleration. Its only when I've just dipped the clutch do I get anything.
. If I change gear quickly its got little if any rattle.
. The only times its been really bad have been after I've done a fair bit of driving in traffic (so slowing down and speeding up by just playing with the clutch) and after a long drive on the motorway after I pulled in to part (so if it is a slipping disc I'd think the heat in it would have been huge).

Now I'm tempted to just say its a bearing or the disk is almost/is dead but I cant afford to drop money on a new clutch if it turns out its a problem with something else.

I've heard about a problem with the PPF being out of alignment. However this is only really seen after a clutch change when its been put back incorrectly I don't believe its ever been removed on my car and its never hit a bump hard (its caked in road grime and has no scratch marks). Also it does not seem likely as the car can act normally if its just driving along at a steady speed. Oh and its not a grinding noise defiantly a tapping of some sort.

just to add I took it for a drive today to find anything else. when I've wormed the car up and driven it a bit hard I get a rattle around 2800-3300 rpm.

I'm starting to think its the clutch plate maybe its not able to put on enough pressure so when it worms up it cant hold the disc.

not a heat sadly shield whole system apart from the cat is aftermarket. I originally thought it was the cats shield but I've struck it a few times and its as solid as a rock.
