Vid below is of the Astra this morning, after I ran it up to temperature, by Maria's....
Note that this was from warm, not cold.
The problem is actually worse than it's ever been, since I changed all the stem seals.... :-/

That's nothing compared to my TD Astra! ;D ;D ;D ;D

Yep, thats a smokie Astra :)

Deffo not right!
could some sensor cause massive overfuelling? prob very wide of the mark though.

Considering the amount of oil coming up past the throttle body, probably not ;D

It's a long shot but the level is slightly over the top mark on the stick - I'm going to drain it out and put correct amount in....

dont think that would be a prob, mine has been like that for the last 2k.
What coulor are the plugs have you checked?
looks more like the oil rings on your pistons mate. so It looks like your going to have to strip the motor again sorry.

Thats a ring.....the head work will have exacerbated the fault

Yep, I concluded that since sealing the top end, will have probably made the problem worse!
Interestingly mark, the compression on each pot is well over 18bar, which I think is maybe due to oil? The tops of pistons are all also wet when I take out plugs and shine in torch.
I don't mind removing the head again, but - I'm really not confident with fitting new rings. It's one of those things that, once shown, I'll be able to do endlessly, but I'm worried about breaking it! :-[

James, you need to get someone with some Vauxhall experiance to look at that ;D ;D ;D

P!ss off ;D
I plan to re-ring it, I won't be beaten :y

Forgot how bad 4pots sound! ;D

try it on nicotine gum,it stopped me smoking. :y :D

Oil control ring James :y
Get yourself a piston ring clamp ( http://cgi.ebay.co.uk/Snap-on-Piston-Ring-Clamp_W0QQitemZ110415424035QQcmdZViewItemQQptZUK_Hand_Tools_Equipment?hash=item19b545aa23&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A6%7C72%3A2140%7C293%3A1%7C294%3A25 ) or split an old oil can and use with jubilee clips (don't laugh used this set up to re-ring tuned 2 Lit (overbored) MGB B-series engine!!).
Really easy to fit rings - once you've done a couple James ;)

Thanks for the encouragement mate
It's like everything else
2.0 cambelt kit - scared stiff until I did one - and now done about 20+ for others
Same applies to V6 kit...
Same to head gaskets....
I'm sure once Ive done rings once, it will be a walk in the park second time around... :y
-
If you decide to go down the route of changing the rings, I'd slip a new set of big end bearings in while it's apart.Won't cost much but will make it more worth the effort. :y
-
Rings are easy enough to fit......sump off is the hardest part!
What state were the bores in?

They actually looked OK Mark - you could see the hone marks on them!
-
Does it have excess crankcase pressure? what happens if you run it with the oil cap loose/off?

Quite a bit of blow back, with cap off...

Unless the breather system is blocked solid, it does sound like worn rings/bores. Easier to do than a v6 top end rebuild though IMHO :y

Just a thought James but if it's a Turbo could it be that at sometime the Turbo has gone and filled the exhaust with oil which wasn't cleaned out properly as you seemed pretty sure that it was the stem seals and the bores looked OK :-/.
