Some more progress today
Firstly, I finished fitting the camshaft housing / carrier, whatever you want to call it. All the journals cleaned and lubed, and all the shells torqued down evenly and correctly.

With the cam locked in position via the locating bolt, I took the engine off it's mount, installed the crankshaft pulley, then brought the crank round clockwise to TDC, and then fitted the cambelt kit:


Interestingly, on every rotation, the M8 bolt fits correctly in the diesel pump, so, it was set up incorrectly before I took it apart. I'm not actually sure what the consequences of this are, as I've always thought High Pressure / Common rail diesel pumps weren't "timed" - but the workshop manual is clear that it should be in that position, so it must be for a reason.
Upper and lower covers fitted:

Manifold, with turbo, refitted (Note, all the turbo gubbins / actuators etc are not done yet)

Air Conditioning pump and various brackets fitted, including one which contains an aux belt idler. Aux belt refitted

Engine back on it's mount;

Oh, and the dipstick tube!
