Head's off:
Cylinder's 2, 1 (1 on right), a fair bit of sooting on the piston head:
Cylinder's 4, 3, 2 (4 on left), some oil leaked out the head as we lifted it off, so has been wiped out of pot 4.
Cylinder's 5, 4 - the bits in 5 are some soot from the gasket.
Underside of the head:
Underside of the head, cylinder 1, 2 (glowplug on 1 is caked in white, so knackered I think), also looks to be some brown scorching next to one of the coolant channels on pot 1, dunno if that's burnt coolant?
Underside of the head pots 4, 3, 2:
Underside pots 5,4
