When the engine is cold all is well, but as it warms up it gets very tappet under load, when cruising the noise is audible but not intrusive, and off the throttle it's quiet.
I did think it could be a blowing exhaust manifold gasket, but can't see any witness marks. Using a long screwdriver 2 of the injectors sound loud, the other 3 are quiet - now suspecting an injector issue, but are they known to run loud when the engine is at normal operating temperature and quiet at other times?
Noise is definitely top end, and towards the centre and passenger side (ie away from belts)
Any pointers?

tape a piece of tissue to a screwdriver to find manifold leaks . check all injectors are coded the same . a replacement may have been fitted with a different code
