How To Service A Caterham Ford Sigma Engine

[@stephenreynolds5777]

Interesting video as ever. The magnetic spark plug socket a really good tool. Great video

[@ACaterhamCalledFern]

Thanks. Yer I wish I had bought one of those sooner. Better than a normal spark plug socket I think. I still can't believe I left the cap off the oil.

Good job, looks great 👋

[@ACaterhamCalledFern]

Thanks the spark plug magnetic socket was ace.

Hi James, great video as always. Iridium spark plugs have a life of 50k miles. I changed mine at 15k miles when trying to diagnose a problem and they looked fine. Going forward I was thinking of changing them every 20k miles.

[@ACaterhamCalledFern]

Hey thanks. I know I change them too much, but I'd rather keep it in my yearly routine and not a massive cost really. I do lots of preventative maintenance to hopefully avoid problems. I didnt know it was 50k, but I'm sure 2 years for me would be fine, possibly more.

Very nicely edited with multi cam views!

[@ACaterhamCalledFern]

Thanks Bert I thought you would like the multi cams 🙂

Do you not have a modine oil cooler fitted? What power output do you have? Liked the video - always like to see other sigmas as gives me ideas 👍

[@artparkinson7371]

And I noticed your front struts are spring down - opposite way round on mine. Any reason why? Again just interested

[@ACaterhamCalledFern]

Hi no I don't have an oil cooler. 140bhp, I don't think I've seen an oil cooler on a sigma before.

[@ACaterhamCalledFern]

Yer it's interesting isn't it. It was like this when I bought it. I think it's because they are easier to adjust, but I'm not 100% sure.

[@artparkinson7371]

@@ACaterhamCalledFern ok, mine is about 160bhp and the cooler is in the sigma build manual. Confused me when I was building mine. It fits between the oil filter and the engine and is on the coolant circuit. Not sure what performance benefit it has though- would be interesting if anyone did know

[@ACaterhamCalledFern]

@artparkinson7371 interesting I'll have a google. I say 140bhp it could be less. It would be good to get it on a dyno and see hey.
