corsa c compretion test ?

If its white smoke then it may well be steam.
Any water loss from expansion tank?
I would get pressure test done on cooling system and sniff test on coolant.
May well be a head gasket

Worn rings & probably bores. Does it improve if you squirt oil through the spark plug holes before carrying out the compression test? If it does, that confirms it. If you re-ring it without reboring, remember to deglaze the bores while you've got the pistons out.

That's what happens when service intervals are extended to 20k miles. You can't beat an oil and filter change every 12 months or 10k miles (whichever comes soonest). Fresh oil is cheaper than a new engine.
