Need help diagnosing a sound on my 986s

[william.patient]

Hi there, really need some help on what this sound is there is obviously something wrong there was no sound from outside the car only the in side. in the video there are some loose coins and a lightbulb I have taken them out and it sounds the same, so it’s not them if anyone has a guest or theory please let me know thanks you.

Suggest you check your polybelt, as may be disintegrating belt.

Remove the carpet on the rear bulkhead behind seats and undo the metal cover and you should see the belt, alternator, water pump, etc and hopefully the source will then be clear.

There's lots of online guides and videos showing you how.

Hope this helps.

That is an unusual noise on any engine I think.
Good idea about the belt above, but the engine will be well exposed with the inside cover off so if not the belt, the culprit could be more obvious.

As above check the belt first sounds more rubber related than metallic.
Good luck with the fix

Hi William,

That really is a weird sound!

In addition to the front cover you may want to remove the top cover to get access to the induction system as well. It does sound rather “reedy”, so maybe something’s flapping around internally there?

Thanks you everyone it looks like a bit of plastic has fallen on my idler pulley.

Nice one - Is it back to normality?

Unfortunately, not as some thing has Fallen on top of my idler pulley I’m not sure what it’s called if you know that would be amazing. i’ll put two photos of what mine look like and a technical drawing I believe it’s number 12 if you know the name that would be great thanks you again.

Ouch, looks like 'Porsche Belts Pulleys Shield Fairing Cover - Part number 99610221105'

It's to stop the cables rubbing against the moving belt and pulleys

Can you access it from the top access hatch to remove and replace it - part number should still be visible on it

It should have 2 fixing bolts accessible from the top and they may have come loose and fallen out, then cover fell forwards onto pulley.

Replacement cover is available from OPC (ask for your PCGB discount) or online

Good luck
