This is disturbing-- There's a post from 'mikem004' lower down this page (18th May 2012 @ 19:20). His post indicates that the earlier K12 Micra has gone through a period of being fitted with a chain which had a reputation for breaking! Perhaps someone has mentioned this to you and it's got you worried? Now, in my opinion, the only way that a timing chain on a normal petrol engine would break is if it's deliberately designed to do so! 'Appen they were being made out of aluminium! Chains normally stretch a bit and get a bit noisy, but a 'normal' timing chain on an ordinary engine should last the life of the car. Belts were introduced because they're cheaper and quiet, but they should be changed at 100K miles on any car if you want to ensure you don't suffer a breakage. Perhaps you should make some enquiries as to exactly when Nissan were persuaded to desist from fitting the toy chains.

The chains never snapped ! (Renault cost cutting at Nissan) They just were not up to the job.

They stretched and in turn put the timing out.

Quite a big and expensive job to do £1000 +

If yours does stretch it wont damage your car,it will put a light on the dash and run badly

2003 cars were affected I think.

Do a Google search you'll find lots of information on this.

Oh,and Nissan blamed everything except themselves on this one and wouldn't pay for the replacement.

Hope I can ask another question regarding my headlights. They are degrading and when I checked them the lens looks like it would clip off, does anyone know if you can just replace the lens without the whole headlight unit.

Cheers
