R34 Gtt Making Strange Rattle Noise On Acceleration

[2000gtt]

Recently my r34 gtt has been making a strange rattle like noise as i touch the accelerator to move (only seems to happen under load). I thought it was to do with the clutch, as i can hear it as im taking off, but it seems to be if i slow to a very slow roll and push the accelerator it will happen... it only last a split second though.

The car did have an occasional squeaky belt which would last a few seconds when i turned it on, but that would happen 1 in 10 times and i haven't heard it for a long time.

This video is the best i could find that has a similar noise...but as i said happens when under load, but it is similar, i might try get a vid of my car if it will help diagnose the problem.

Oh and it seems to be more noticable after the car has warmed up, barely noticeable on a cold start.

Any thoughts would be great, thanks

Have you checked all your exhaust/turbo manifold/dump pipe etc bolts yet that would be a good place to start

no i haven't, but one thing to note, the car was too low at one stage and teh exhaust did cop quite a pounding on speed humps etc... it has a nice dent on the bottom of the muffler, and a small one on the cat... (its since been raised)

I tryed to get a video of it today, but it wasn't noticeable on the camera, would a noise similar but less intense to the video above be signs of a exhaust leak?
