If I'm thinking about the right engine, they use timing belts, not chains.
What year is it? 8v or 16v? The 16v ones use two separate timing belts, and as far as I'm aware neither have an hydraulic tensioner?

Thats what it looks like under the bonnet Belt - the cover hides it but belt all the same It's more than likely one of the oil pressure switches has failed - run the engine and look in the oil filler cap when it's running should see oil around the valves/cam flowing out and draining down the head - that will mean you have oil pressure If you haven't got signs of oil up there then a tow is a good idea and then some better investigation is required have a link or two uk.answers.yahoo.com/question/index?qid=20100813102354AA0CPSj195.10.244.9/forum/post/index.htm?t=60341

The AA man told you the timing chain is tensioned by oil pressure, and it's clearly got a timing belt, which is clearly not tensioned by oil.
Seriously? What kind of chimps do the AA employ?
It makes me weep how many uninformed people get ripped off by this utter garbage advice they give out. My missus was almost one of those, another KA, 'it's your head gasket love'
On a more positive note, my wife used to have a 6N2 Polo with that engine, it had the same fault and it turned out to be the top oil pressure switch (one in the head if I remember right)

I have had better experience with the AA than you guys. Always found them to be cheery and helpful and usually pretty knowledgeable. Usually its either something I can fix myself/limp home or something so catastrophic that I need a flat bed truck to take me home. It was years ago now so I forget if it were the RAC or the AA who changed my cam belt at the side of the road after I snapped it. Got the timing spot on as well. Great job. I did get one who told me that a split on an electrical connector was causing an oil leak but I gave him the benefit of the doubt. Maybe they don't try BS me because they assume a guy with a broken down Buick/Cortina/Laurel/whatever is going to be the sort of chap who can spot the BS as it comes.

*overarm slings his humble pie at the AA man* First thing is to check the oil pressure switch in the head as mentioned above. In fact swap it out as a matter of course - when the diaphragm fails (and it's a common fault) you get one monstrous oil leak. It's on the back of the head slap bang next to Cyl.1. and I think it's a 22mm hex. THEN, contact the AA in writing (google the CEOs name and contact details), and clearly state you grievance. It may sound old-fashioned, but I was left stranded for four hours on a clear night on a main trunk road after a patrol went to entirely the wrong place, so I wrote my complaint and was offered a year's free cover by way of apology.

Where is the tapping coming from? Top or bottom of the engine? Has it allways been tappety? Has it got MORE tappety since the pressure light came on?
If the tapping is coming from the top of the engine (hydraulic lifters) Then its likely the oil is too thick from being cold and not getting into the hydraulic lifters and causing the rattle, Could also be that its not getting into the pressure switches quick enough/ at all.
If the rattle is coming from the bottom then its gonna be the oil pump.
Realy need to know how bad / how long this rattle has been going on..

Tappetyness is brand new its never done it before. The oil light doesn't come on straight away. A good 2 or 3 minutes before it comes on.
It did sound absolutly smooth beforehand and has only done 40k. Its not terrible and not something id have worried about if it wasn't for the pressure light. It has however felt slightly down on power for a good 2 or 3 months

In that case, As you have had both the tapping and the light come on at once, You need to be narrowing it down abit. I.e find out where the noise is from..
And don't waste time just fitting new switches and hoping, I don't think that would be worthwhile, Plus you might end up with a dud switch and assuming its all fine and dandy. Assume the switch is right. Especially as its joined by a tapping and lack of power.
Id be guessing at a pump. Either that or its very strangly decided to pop a tappet and an oil pressure switch at the same time.

I must say it sounds like the engine has genuinely got a low oil pressure problem. The AA story is nonsense, ignore that completely. I would get a garage to check the oil pressure independently with their own gauge, if it really is low its gonna be a oil pump or oil pressure relief valve problem.

Some chain engined cars are tensioned by oil pressure (24V cossie i believe) and some belt driven cars have an oil filled tensioner but they aint directly pressurised by the oil pump in (VW/audi 1.8T) springs to mind. IME if the oil light comes on after a while and the top end starts to rattle you have play in the mains (crank bearings) although as said earlyer i have had problems before with the twin oil sensors but this sounds more seriouse IMHO.

The way it would be paid for would be selling the daily swmbos seat ibiza. Oil pressure light just came on on mums car. Car in question is a Seat Ibiza 1.4 Do your Mum and your GF both have Ibiza's? That's lucky ;D Maybe you could get the two cars together and compare engine noises to see if your Mum's one really sounds that bad or maybe your just reading/listening into it too much because of the oil warning light? Having the two cars back to back would make a good comparison. I hope you get it sorted.
