HI RubikCube
Some kind person posted me a link to an on-line manual when I last worked on mine.
Hi Folks A few days ago Zardo kindly let me have a link to the repair manual which may answer my query; but, being an oldie with technology, I can't find his post again! So, where might I find the valve clearance specifications for this engine, and the setting procedure? I would normally...

Depends what you are planning to do. Fluid and filter changes are quite straightforward, but valve clearance check (surprisingly they are NOT self adjusting hydraulic) can get quite involved largely because of the need to remove the cam box cover and reset the cam position sensor position which requires a special alignment tool. Thankfully these are reaonably easily available and not too expensive.
If the valve clearances are out of tolerance you will need to remove the shims. Thankfully, they sit on top of the buckets so it shouldn't be too difficult to remove / replace them providing you have the right tools to compress the springs, flick out the shims, and measure their thickness. Mine was a head gasket failure so it was a head off & strip job anyway so there was no need to remove the shims 'in situ'. At 60,000 Miles mine were still nicely within tolerance if that's any comfort to you.
Great care needed if you are replacing the cambelt. Use the correct locking tools to lock (1) the crankshaft, (2) the camshaft in the head and (3) the VVC pulley relative to the cam. With these precautions you should be able to avoid making the mistakes I did that a good few very knowledgeable guys on here helped me resolve.
Good hunting
