Jon's Bodge Log - The Peugeot continues to be ungrateful.

That camshaft pitting doesn't look fatal but could indicate oil starvation, which these engines are well known for. 

Particularly due to the design of them where the injectors are exposed to oil, so if they leak combustion gasses then it finds it way into the oil which absorbs carbon. It all goes a bit south from there as it starts to block everything up. 

If you feel like doing a bit more preventative maintenance, dropping the sump and checking the oil pickup may not be a bad idea, and possibly checking the oil feed to the turbo and replacing the feed pipe if necessary. Again, this oil pickup blockage is well documented as being the cause for turbo failure on the DV4/6 engines.
