Steve Q Posted August 19, 2022 Share Posted August 19, 2022 Normally the chain will start to clatter I believe. If it sounds smooth then I would leave it in my opinion. Quote Link to comment Share on other sites More sharing options...
K3v Posted August 20, 2022 Share Posted August 20, 2022 It's an engine out job to change, with the costs that come with that. When I had mine done it was a guide which had broken, horrible clattering noise when the engine was under load but only for the first minute or so when starting the car from cold, also couldn't bear it with the windows up. My chain had stretched as well but I believe it throws up a timing error if it stretches beyond a certain amount which mine hadnt. Change the oil every 10k not 18 supposedly helps the lifespan of them. There is no recommended mileage to change the chain/guides, it's not the same as a timing belt in that respect. 1 Quote Link to comment Share on other sites More sharing options...
