I found my 12 point 12mm socket has departed to greener pastures,, so could only check top exhaust manifold nuts with ring spanner,,
and all ok,, and all the flange nuts were good,, and both lower joins showed no black marks,, 
it does sound back there somewhere--  [bighmmm]
also checked front pads and discs,, none of them low enough to warrant the top up I had to do last week,,
not sure the backs get used enough to be concerned,,
maybe a job for Wattlemere ;)
