Mini Cooper 2011 chain snapped

Seen a Cooper 2011 with suspected chain failure
Are these engines as straight forward to repair as the 1.6 petrol
Or are there more specialist tools and knowledge required to fix

is it the n47 engine the bmw engine. if so you are in a world of hate, first off the n47 has its timing chain at rear of engine between the gear box bell housing and engine block, stupid at it very best bmw moron that decided the m47 diesel needed changing it that way the early m47 used 2001-2007 was a total peach very mappable daughter has a a compact got 245bhp bmw at wheels after a few mods and diesel additive from bio diesel increases the bang done 150k still works perfect,,
anyway if n47 bmw own engine then engine or gearbox out, special locking tools

two links above. the all the valves i would expect sometimes they snap valves and then it piston and head damage, look at the job at worst need a head and some pistons, i would fit secondhand pistons and re ring and hone the bores and big end bearings etc.
if its the 1.6 hdi then there is a chain that links the cams together and has a timing belt to run cams, if chain gone the injector posts need removing and they are a total ******* normally will need 3x8 mm locking nuts to remove them with as the torx tops break off on them a lot. also very important when rebuilding the cams sit in the cover this cover must be torqued down 10nm no more no less, if over do them cams will fail within a few hundred miles or turbo as they wear the oil pressure will fall away..
good luck with it i'm removing myself from forum so wont be available for any more help on it,
