I have a Vauxhall Corsa D 2014 1 litre around 35,000 miles. Occasionally when starting it will make a loud noise for 2 seconds and the engine will make a sort of jump then go normal, a local garage has said it will be the timing chain than needs replacing but just wanted some other opinions. I have a video of the noise and the timing chain but can’t attach but would be able to send via/email text. The garage also said that I may aswell get my service which is due done at the same time as they already have to replace the oil filter so might aswell make it apart of the service. I have been quoted 629 for a timing chain replacement and a service. Any help would be highly appreciated.
