Timing was out, because chain had stretched, probably caused by oil starvation, maybe down to an oil nozzle which they’ve changed since they go this far. Head had to come off to enable disassembly of timing chain guides. Going off for a light skim.
Good news is that bores, pistons and valves on the exposed bank are in v good nick. Edit: also they are sorting out the oil leaks and infamous ‘prone-to-bursting buried coolant pipe’ while they’re there.
