Sounds alot like the timing chain to me (I had the same with mine). After going to a number of garages I was quoted between abotu £150 anywhere up to £500 to have the chain/tensioners replaced. The cheaper qutoes were for the chain only, the more expensive were for the full kit including tensioners.

Ok, ive been looking at the engine for about 2 hrs 2day. The exhaust manifold is secure, bar the one bolt on the very front cos it was sorta rusted in place so i cudnt get it off, but its been secured with cardboard :). I cant see anything else out of place, apart from lots of oil and grime. When i started the car up the rattly noise is still there, and its localised to the inside of the engine, left side where the belt is, making me believe its the timing chain thats got loose. How much am i looking at to get it tightened and/or replaced??

Just a quick update. The noise has avenged itself. Its very easy to hear it on idle, its a bad rattle, when i rev it a little the noise increases in pitch, but u cant hear it over the sound of the engine when driving. Also its lost a little bit of power as well, not as responsive as before.

My money is still on the timing chain mate. place a solid metal bar (like a socket wrench or the normal wheel brace) on the plastic cover and you should be able to hear it better if you put your ear next the the end of the bar (sounds strang I know, but it does work)

Yup still making that odd noise. Its still driving normally as well. I will try and localise the area where the noise is coming from. Then i can go from there.

I suppose you could check the engine itself for any signs of freshly leaked oil (sump gasket, sump nut, other gaskets/seals) but personally I wouldnt worry too much over half a litre. Just keep an eye on it and see how it goes.

I cant see any oil on the road, there is no mayo, and exhaust fumes are normal coloured. I did think of head gasket, so i checked usual places, but nothing appears to be out of order. I shall run the new switch in and see if that makes a difference. Is there anything else i can be checking in the meantime?

Have you got any patches of oil where the car is usually parked? (ie where its parked alot, driveway or outside house)

Right, just changed the switch, very easy job. Part cost me £4.90, which is reasonable. I also discovered oil and coolant loss as well, which is worrying. Oil had gone down about half a litre and coolant was down about a centimeter from the cold line. All this was only topped up a cpl of weeks ago. :boggle:

I think so mate, fairly straight forward job. Just get the switch changed, check your oil and keep an eye on the noise...

Its done 65,100 miles at last count. I know that the oil pressure switch needs replacing cos it sends sum oil dripping down the side of the engine. What i will do is replace the switch and see what that does. Is it litrally just one bolt, replace switch bolt back on?

sounds like the timing chain to me tbh. Its quite common on these engines IIRC

Yup, bit of a rattle. Sounded more like a random vibration near the back.
||posted on 20th Jun 08 at 14:58|
what sort of noise is it? rattle? sound like metal perhaps?
||posted on 20th Jun 08 at 14:56|
Just been outside. The noise is coming from left hand side of engine, near the back about halfway down. When i rev the shit out of it the noise goes away, but then comes back. I checked the belt, and its not slack or anything.

strange noise :boggle: whirring, rattling, knocking, mooing :boggle:
||posted on 20th Jun 08 at 14:36|
Timing belt or tensioners need changing maybe? I had a similar problem on my sport and that seemed to sort it :thumbs:

Basically over the past week my engine has sounded different. On idle there is a strange noise coming from the belt area to the left of the engine. Whilst driving it sounds ok. Engine is 1.0 12v. any ideas?
