Rev related rattle

[Night Runner]

Evening all,

I have a '96 mk1 1.8 which has developed a rattle.

It only happens if you are running steady at >4,000 revs or when you put the clutch down.

It's a tinny rattle, I'm thinking a heat shield or something.

Anyone able to give any pointers? I'm planning on getting it on the stands for the 1st time after work tomorrow.

ETA: Thanks!

I think some of the heat shields which rattle are the one in the engine bay, the one around the cat and there's also one right above the backbox. I don't know what makes these rattle, I've just read that they can.

I have a rattle myself, but it seems to be coming from the rear left brake and I'm having a tough time tracking down the cause.

Is this in all gears or only in 4th? Does it also do it but to a less extent at 2k?

Pads anti-rattle clips present? Hand brake adjuster screw loose?

I have a massive rattle at the moment which I've narrowed down to the downpipe heat shield, it's pretty annoying but doesn't matter much.

If you can, get someone else to hold it at the annoying revs and get under it with a hammer and hold it against various parts until the rattling stops.

An update-

Not pinned it down yet, however it doesn't do it in the rain- when the roads are soaked hmmm...

Ive got an audio clip I'll upload when I can.

Still trying to get it booked into the garage- I keep forgetting

tut tut!
1st, 2nd, 3rd, 4th - haven't noticed it in 5th, mainly as I'm not in 5th at those revs much.

It will do it at 2k+ revs it seems to be when the engine in under load - when its making the noise and I press the clutch/ease off the power it will stop...

I'll put £3.50 on it being a manifold/downpipe/exhaust heatshield

It's now booked in at the garage. They think it may either be a heat shield or the cat.

If it's the cat I can either have it replaced or a thru-pipe put in place, would that make it horrendously loud?


Cheers
