Disco 2 Clattery noise under bonnet

On idle, once off idle it is OK.

Also tends to shut up while looking for it.

APPEARS to be top left near all the pumps and compressors.

AC works, steering OK, goes round corners flat.

Sounds like something plastic tapping metal at about 2 to 5 Hz can't get more accurate than that. So less often than 1 engine revolution.

Just had new radiator but it is not that, first thing I checked.

Just wondering if there are any known fail noises for stuff under the bonnet.

Could it be the heat shield around the turbo?Mine rattled as all the bolts had dropped out.

Don't think so, seems more forward.

Being intermittent doesn't help.

Idler pulley bearing? Slacken off the belt and give it a jiggle. Should be no movement at all.

That is other side and down the bottom, I will have to remove the covers again.

Intake pipe clip will move at weekend, need rear calipers though

Snot just a rattly tappet then?
Does it go away as the engine gets warm?

The turbo to ic pipe was refitted with clip bashing inside wing.

Will sort myself at weekend.

Using garages always need to check after.

I will pay on some jobs to avoid pain
