Its likely you've got the breather pipes all clogged up. Here's a pic showing you which ones they are (the ones coming out of the rocker cover that go to the intake). Use a pair of pliers and gently remove the clips and pull the two pipes off and clean them out. Also clean out the openings where the breather pipes are plugged into the rocker cover and on the intake.

Once cleaned, the engine should have an easier time getting rid of moisture in the oil. Also, you need to have at least once per week that the car is driven for an entire hour or longer without turning the engine off so that the engine gets hot enough to boil off the moisture in the oil. Constant short trips like 5-10 minutes here and there where the engine cools off in between will only cause trouble.

The head gasket usually doesn't fail unless the engine has overheated at some point which causes the head to warp.

Check your coolant level in the overflow tank when the engine is completely cold in the morning and whilst parked on a level surface. Maybe even mark the exact level on the outside of the tank with a piece of tape.

If the level doesn't drop noticeably when measured cold over a few weeks, then you're not losing any coolant.

Another thing is that there's a vulnerable spot on these engines near the water pump, which bolts to the timing cover. The timing cover has a rubberized metal foil gasket where it bolts to the engine block. This timing cover gasket has a spot where on one side there's coolant flowing through it, and on the other side there's oil. Sometimes this gasket fails at this spot and the coolant finds its way into the oil. This actually happens much more often than the head gasket going on these corsa engines.

But first, check to see if you're losing coolant over a few weeks. If your coolant stays level and the engine runs fine then the only thing you need to do is maybe change the oil and keep it from mayoing up again by doing a long trip at least once per week.

From how you describe this, the answer you have been given is just about sure to be spot on.
At this time of year in particular, you will get a lot of condensation in the engine which will emulsify the oil mist, leaving the deposits that you describe.
Condensation in the exhaust system can take quite a long run to dry it out completely.

Regards
