Rav Posted July 13, 2020 Report Share Posted July 13, 2020 Hi All - I started up my car as she really hasnt seen sunlight this year and noticed a rattling on idle. I will try and film this and post, but it did sound like a heat shield or similar. Any ideas what to look for when i get underneath? R Link to comment Share on other sites More sharing options...
jonogt6 Posted July 13, 2020 Report Share Posted July 13, 2020 I'd try the heatshields that attach to the catalytic converters as the first place to look. They're notorious for rattling once the fixing point corrodes. Alternatively it could be the aluminium linings that fit inside the rear bumper.

EVO Chris Posted July 13, 2020 Report Share Posted July 13, 2020 Are you sure its not a stuck lifter, give it a run and see if it clears....Boxsters can suffer that after a lay up. Link to comment Share on other sites More sharing options...
½cwt Posted July 13, 2020 Report Share Posted July 13, 2020 A stuck lifter is more of a ticking noise rather than rattle. I have one that seems to stick on start up if I leave it for much more than a week. A rattle could also be due to worn timing chain guides if you can't find an external source like a heat shield.

I pretty much mirror what he says ^^^ @Rav if you fancy a little run over to my house which is about 11miles from you I would be happy to have a listen and see if I can figure out what's going on.

Boxob Posted July 13, 2020 Report Share Posted July 13, 2020 Is it a tinny sounding rattle just at idle? If so, then odds on it's one or more of the four heat shields (2 over the cats and 2 around the exhaust pipes before the cats). Link to comment Share on other sites More sharing options...
mortzz Posted July 13, 2020 Report Share Posted July 13, 2020 I have a rattle on start up only when cold , it's been tracked down to the cam chain adjuster, apparently there hydraulic so for a few seconds it rattles done it for over 12 months Link to comment Share on other sites More sharing options...
Lozzer Posted July 14, 2020 Report Share Posted July 14, 2020 I had a tinny rattle that appeared from nowhere - turned out the exhaust clamp had corroded so much it had come apart and was rattling on the pipe. Link to comment Share on other sites More sharing options...
