Hi

So car's been lying up over Winter with the occassionally start up and drive about to keep things from seizing up. I noticed today when I started it there was a sound that lasted for a minute or two then went away, what can only be described as a clinking metallic sound from around about the drive belt area. It was hard to pinpoint exactly the area it was coming from as by the time I noticed the sound and started investigating, it disappeared.

Hopefully this google video works on here if not let me know and will upload it to another sharing site.

nothing been done on car recently, last thing done was belt in 2021, and everything seems ok last time I was in there.

hard to be 100% sure but i can hear it. obvious checks as to wether water pump pulley and others are not loose . could try it with aux belt off if its a regular sound every time ?
sounds like i once had when an exhaust clamp was fractured but there arnt any that near that would be so obvious ?

Check the waterpump pulley bolts and that there's nothing touching the pulley itself.

Will have a better look at the weekend and report back any findings, thanks

Checked all the bolts for the water pump, steering pump and only thing I could find was a bit of play in the aux belt tensioner, considering it's still got tension on it, imagine it might have a bit more play in it when tension is off.

Need to remove it and check. Funnily enough I just ordered a new spare one last year, I also greased up the existing one the last time I did the belt. Still, a strange noise to get from a worn tensioner, would have thought it would be a more dry constant dull sound, if indeed that is the issue.

Is it a sticking valve lifter  not uncommon if the car has been left un-started

Don't know, it sounded round about the aux belt area. Very high pitched, but not loud really, almost like someone was tapping a spoon off something metallic. I'll start it up tomorrow and see if I can catch it a bit earlier this time.

It did sound like something pinging against the water pump pulley.

Of course, nothing to say that it isn't coming from inside the waterpump.

Belt off and check it for any play or roughness, ideally from ice cold rather than just running.

Will give it a wee start up tomorrow see if I can get a better idea where it's coming from. Got between now and April before it goes back on the black so got some time for strip down and check (The car, not me!)

You need to spin the pulley by hand BEFORE you start it.

Ok, will do that first.

So bit of an update, but not really positively identifed the issue. I decided to take the aux belt off and check/spin the pulleys before it started, nothing that I could feel or hear wrong, apart from that slight play in the tensioner pulley.

Then started it up without the belt first to see if I could hear anything, nothing, then put belt back on to see if the noise came back, it didn't. I was half expecting it to, but then thought maybe playing about with the tensioner moved something in it, if it is that at fault.

After that I noticed a sort of low dull repeated scraping from what sounded like behind the belt cover, and when I put my hand on it, I could feel this dull repeating scraping sound.

So, not got to the source of the original problem, but now got another, and it sounds deeper this time! Need to do a bit more digging.

Change the tensioner pulley and report back.

If the problem is BEHIND the belt cover 
you best STOP using or even starting the car and check the timing belt etc  PDQ
a shredded timing belt ,due to failing tensioner, idler or just bad belt only makes a repetitive sound for so long 
then the engine dies

Done in 2021 apparently.
