Yes I have already checked there's no school child caught up underneath.get this sound just above 2250 rpm but only for the first mile or two and only happens under load so I would guess turbo leak tho no loss of performance hoses look good intake gasket?

Might be an exhaust manifold leaking at the cylinder head joint due to warping

If you do replace the exhaust manifold gasket too, get it skimmed or a new one for about 100 quid, new gasket wont fix it.

Ok thanks I think I have found the problem there's a little soot patch on the exhaust gasket...well to be honest thought this would come back to haunt me as had to change the head and got a "recon" one only found out after fitting that one of the exhaust studs had striped the thread inside the head. recon head....my arse!!!!.
