NeilGC Posted April 9, 2023 Share Posted April 9, 2023 I feel sure that this question must have been posted before, but I never seem to have much luck with the search function. My Sigma-engined Roadsport 125 has only done 21,000 miles in 14 years since new, but has never had the timing belt replaced. I realise that Ford say every 6 years (I think), but does that REALLY apply at such low mileages?Opinions welcome...thanks! Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted April 9, 2023 Member Share Posted April 9, 2023 I haven't seen nearly as much about that as on K series engines.But there are discussions of tensioners and water pumps... and how easy it is to DIY.Full search of the archives: https://duckduckgo.com/?q=site:CATERHAMLOTUS7.CLUB+sigma+timing+belt+changeJonathanPS: You're not alone with having problems searching. That URL above uses the best method that I know. It's discussed here: https://www.caterhamlotus7.club/forum/chitchat/search-facility-1 Link to comment Share on other sites More sharing options...

Area Representative Paul Richards Posted April 9, 2023 Area Representative Share Posted April 9, 2023 14 years!!!!! You're on borrowed time. It's not just mileage related but age related. Get it changed now. Link to comment Share on other sites More sharing options...

StevehS3 Posted April 10, 2023 Share Posted April 10, 2023 I changed mine at 6 years and I would definitely change yours as it is overdue on time but Ford claim a very long life https://www.pentagon-group.co.uk/ford/cambelts Link to comment Share on other sites More sharing options...
NeilGC Posted April 12, 2023 Author Share Posted April 12, 2023 Thanks for your opinions everyone. It's annoying for 'cherished car' owners like us that Ford themselves say that it can last 100k miles yet should be changed every 6 years (10k miles in my case), but I do get it. It's now booked in to have the belt changed.Next question: what about things like fuel lines, brake hoses, etc that Caterham also say are time-limited. Worth replacing even if a service/MOT doesn't suggest they need it? I think I can guess what you'll say! Link to comment Share on other sites More sharing options...
Area Representative Paul Richards Posted April 12, 2023 Area Representative Share Posted April 12, 2023 I'd suggest a physical inspection of hoses is adequate and change if any signs of damage or cracking. Link to comment Share on other sites More sharing options...
simon_h Posted April 12, 2023 Share Posted April 12, 2023 This obviously only applies if you are getting a non Caterham specialist to do the belt, the Ford cam locking tool doesn't work as the cam timing is adjusted to take the 105hp engine up towards the claimed 125hp. Just worth mentioning it to any ordinary garage. Link to comment Share on other sites More sharing options...
