It has come to light that early K12 Micra's, ie; 2002/2003 had very weak timing chains that stretched, even at low milage, my Wife has a 2003 Micra with only 25k on the clock, but, it turns out that the chain has stretched! Has anyone any experience of changing the timing chain on one of these?

It's a hugely involved job which is best done with the engine out, you'll be delighted to hear.
The job has been covered in recent Car Mechanics magazine, and there are specialists around who will hugely undercut Nissan prices.
I'll not say it's common, but it's not unknown either......the Primera and Navarra are huge offenders.
My own research indicates that it's not a lubrication issue that's the problem.
You have my sympathy here!

Cheers John, my own research and talking to Nissan tech's show the early K12 2002/2003 had a crap batch of chains which were made of chocolate!! The chain stretches to such an extent that the tensioner piston which is usual out @ 8-10mm is showing 20mm!! Your post confirms what I have read, ie; engine/box out, I was hoping someone had a rough price guide to do the job, Nissan are looking at £800 - £1000!! I've seen the chain kit, ie; chain, tensioner, guides, both cam cogs, one of which controls the VVT, going on ebay for up to £300!! This looks to be an expensive repair for what is essensially a nice cheap little car.
I did an almera years ago and it was an involved horrible job but with engine in. The chain, guides and tensioner kit were about £90, the chain was stretched to bu**ery and the adjuster was maxed out on removal.
I didnt see the need to change any sprockets/gears so didnt bother as the chain is the problem.

Dammit, that sounds like total misery
I suppose the alternatives are to trade the car on and say nowt, source a complete second hand engine or go for the repair.......sadly the car isn't worth much.
Seriously bad crack.

There's a firm that replaces motorbike hy-vo chains in situ - presumably using a riveted link. Just the job, that one as bike chains are frequently around the centre of the crank.
There's got to be an opening for that repair here!
