Cold start rattle?

[MickJ]

I'm not unduly worried about it, but is this a common thing on these cars, when starting from cold (stood overnight) the revs shoot up to around 1500rpm and then I get this light rattle for a second or so which sounds very much like the hydraulic lifters pressurising, it's not a heavy knock like ends, also it won't do it again unless left for example overnight.

 

Any thoughts.

 

Cheers Mick
