I am impressed at your enthusiasm at dismantling this engine .... it's years since I've seen inside a block like that.

I don't know about this Astra, but I bought an Astra G diseasal a few years back as a none runner ... completely different engine, but the cam shaft sprockets were not splined onto the cam shaft as per a V6 Omega, it was only held in position by a taper. I realised just before I released the bolt on the end. 

Still are on many engines 

So I now believe  Seems a bit barmy to me 

the key in a 'normal' pulley is only there so the timing marks are correctly placed, it doesn't provide the drive. It actually makes more sense putting the timing mark(or lock) directly on the shaft, and rotating the pulley to tension the belt

The bore is cleaned up, and the piston is back in:

It's worth noting there is still a bit of "staining" a it were on the wall, but, it's silky smooth to the touch, and as good as I honestly think it's going to get

You seem to have got hold of the parts quite easily.

How much was it? 

Last piston I bought was the best part of 40 yrs ago for a Ford Pinto .... Ford wanted £25 (a lot of money at the time) I got one from a local engine rebuild bloke for £9 (and he pressed it onto the gudgeon pin)

Set of  new rings for this car is £30 a piston, for pattern parts. No idea about GM.

I paid £60 for the piston second hand with the conrod attached. Whilst it sounds like a lot, it was worth it, rather than buying a new piston at £90, and having to mess about with oven / blowtorch / freezer to press the gudgeon pins in and out of my old (possibly bend) conrod

Excellent and you won’t go wrong I’ve used second hand pistons and rods in the past and had very good luck👍👍

Sounds pretty reasonable 

[Viral_Jim]

Agreed. Not having to part with three figures for the piston/rodis good value imo.

Tomorrow's day is is a simple one, because I've ran out of parts to put the top end together. So I am going to:

1) cleanup and refit of lower sumps, and ancillaries like the dipstick tube and strainer, etc.

2) General tidy up / sort out of tools / work station.

If time is left over, I might

- Remove the DPF, and do a post mortem

- Pop out the valves on no4 and check the seats

Just sit in the sun and have a beer!

Just ordered the top end gasket set. £60 delivered

£25 on 4 rocker cover injector seals as I broke one on removal

As it stands, this beast will have been purchased, trailered to me, and fully repaired all within three figures
