The Corsa now has fresh oil (5W-40 full synthetic), a new filter, and the metal plate for the warm air intake has been reinstalled (the threads were cleaned and one was newly cut).

After the mucus, I'll need to take another look.

Greetings.

"Good. Regarding the 5W oil, does it also meet GM specifications A-025 / B-025? If so, it would even be considered LL (Longlife)."
I experienced noise issues with the 10W40 HC oil in a fleet customer's vehicles, particularly during short trips.
The 1.0 3-cylinder engine likely has a hydraulic chain tensioner that doesn't perform well with thicker, colder oil.

Okay, please provide the text you would like me to translate from German to English.

I took the car out for a drive of about 100 kilometers around the area last Friday night.

It didn't really make much of a difference. How can I get rid of this stuff for good?

Lower the VD (ventilation duct), remove the KG (ventilation shaft) vent hoses, and clean everything = a short-term solution.
Avoiding short distances = a long-term solution .
Edit: I have one more.
The plastic ventilation hose would need to be replaced with a metal one, and a glow plug would be used to heat it to over 100°C.

Hi,

The small amount on the lid is purely cosmetic; what's most important is that the oil is free of water again and that the layers in the storage container have dissolved. } The small amount on the lid will probably disappear in 2-3 months. } Just wait and see. }

Do you mean?

Does it disappear because it's getting warmer?

Because recently, it's been happening more and more, even though I replaced the thermostat and the car is warming up again now.

It's just a city car .

And the differences mentioned earlier were due to driving 100 km... I had hoped for more.

If the head gasket is in good condition, or if the water consumption is zero, then yes.

My sister has a 15-year-old aluminum engine (with only steel cylinder liners), and it looks like that on the oil separator in the winter as well. If I change the oil in the summer, nothing is visible.

In the summer, you can quickly experience air temperatures of 20°C or more in the city after turning off the engine, and there's also less wind than there is now. Those few degrees of ambient temperature have a significant impact on how quickly the car cools down or heats up.
