Strange underbonnet noise?

Yes it is the one behind the swirl pot that you pointed out that went and was making an intermittent grinding noise on mine - I limped mine along just sticking grease into it for nearly six months before it failed. 
TBH - if you can get access to the press you let your mate have it's a piece of piss to change ... I got the bearing from www.simplybearings.co.uk and it was a "33052RS Budget Rubber Sealed Double Row Angular Contact Ball Bearing 25 x 62 x 25.4mm" ... was about £33 IIRC.
Of course you need to confirm that it is the idler and that's fairly obvious if you spin the idler pulley by hand once the belt is off.
Sorry, I forgot to put a smiley after saying I gave any press to a mate, I wouldn't even know what one looked like. Is it something normal folk really have in their garage? Is it affecting my status as a man not having one? TBH - if you can get access to the press you let your mate have it's a piece of piss to change ...

I'm gonna have a pop at it later and report my findings.
We have progress 
I was brave and took the belt of this afternoon
It's a big thing for me and I'm well chuffed 
Anyway, the pulley behind the swirl pot turned freely with no play BUT it did grind a bit and I mean a bit. The other pulleys, that I could turn, were smooth and easy.
Does this sound like the problem? If so, what is the nest step, how do I get it off and where do I need to take it?
I'm rather excited by my new found manlyness and ability to do spannering.

Give the front bearing area a squish of WD40. Another squish 10 mins later and check if it feels less rough. If so, sounds like the bearing. New WD40+silicone looks an improved product.
Right, that's done. It initially sounded worse, more pronounced grinding if you will.Could that little noise really be so loud under the engine bay? Seems mad. Is the pulley easy enough to remove?

This should help if it is the power steering pump bearing we are talking about. The swirl pot on mine needs to be removed to get at the pump bolts.

It does sound like the bearing might be on the way out if it feels "grindy" ... it should run smoothly and mine you could easily hear over the engine when it was grumbling.
It's a piece of piss to change ... pop the belt off, undo the three bolts that hold the pulley onto the pulley flange and remove that (no need to take off the swirl pot or drain any coolant). Then you can remove the bolts that hold the pulley bearing housing onto the carrier. Once you have the housing off then there's a bolt the other side of the bearing that holds the shaft in the bearing - undo that by holding the pulley flange in a vice and the pulley shaft should then be easy to just knock out of the bearing from behind.
Then hand the housing and the replacement bearing to someone with a press and let them do 30 minutes work.
Refitting is the reverse of removal.

Cheers Phil, I'll give that a go later. Out of interest, in the other thread you mentioned that you wouldn't use a budget bearing if you did it again. Did you source a suitable replacement or stick with the budget item in the end? Will it be worth the extra outlay? If so, do you have a link please?

Oi! That's not very nice Think of the untold damage I could do if I refit it wrong. My previous experience of underbonnnet spannering is limited to oil/lead/plug changes and getting my finger mullered by my ex father in law whilst holding a socket in place while he put his full weight on it

Just remember take your time, and if need be take a few photo's of how things were before removal etc

Hence the excitement at completing what is probably the easiest job on the car, apart from filling the tank with diesel

I wouldn't even change that belt myself - bound to get the tension wrong and foobar something expensive!We are all different and have differing abilities.......... mine are just rather different to anyone else.

Well done - I bet you feel quite chuffed with yourself now?
Does that bearing feel "grindy"?
You're doing better than I did - I kept putting mine off till it seized solid with a girl in the car that I was trying to cop off with which p*ssed her off enough that she's never spoken to me again - oh and when it siezed it also gouged two bloody great lumps out of my swirl pot!
...of and with the spring loaded tensioner you can't set the tension wrongly. So don't worry about getting that right.

I used the budget bearing and it's still absolutely fine - however I do wish I'd used a better quality metal sealed one but only because I know it has a budget one in there and my man brain nags me about being a cheap b*stard ... it's not under that much load and is probably better than what went in in the first place at TVR.
