The aux belt along with the aux belt tensioner and aux belt idler pulley have all been changed. Still the rattle occurs (hence my suspicions of the crank shaft pulley but as I stated in my first post, spraying water on to the crankshaft pulley while the rattle is present, doesn't change anything, the rattle persists (for a few minutes until the engine begin to warm slightly and then the rattle fades away).
(I have checked the upper inlet manifold flap rods and there wasn't any movement (up n down?) Can't remember there was play one way but not in the other direction that is said to be the play that causes the rattle, so I ruled the fanimold out. ��

I have watched the kv6 belt video on YouTube, looks easy in fairness (brand new engine, not in a car so.. will see how that pans out).

I don't have the latest tools and electro gadgets, hand tools mainly accompanied by longer bars for extra leverage on highly torqued bolts etc. (Usually a T bar and impact socket affair with different length tubing which slides over the handle of the T bar. (Broken many of those strong bars over the years, I find the swivel head joints snap).

Did the thermostat and all the belts, pulleys etc. myself not long after I got her with 118K (and plenty of past dealership invoices/history). Engine in situ. no special tools just worked my way through it using Haynes and lot's of how-to's off here. Marked the old belts and pulleys with correction fluid and just put all the new stuff back accordingly - bit of a ball ache but worked out fine.
Now done 165K and runs fine.
The rattle could just be the slightly drained oil galleries for the followers. As soon as the sytem becomes fully pressurised (and it starts to warm up) the noise disappears - I would suggest it's quite normal if indeed this is the issue you think you have.
