Astra H Oil found in coolant

Question

What should I check/replace now?

I already replaced a set of gaskets in the oil cooler. It did no help.

Engine Z18-XER. Year - 2008.

Nothing else happening. No white smoke, no external oil leaking, no external coolant leaking. No unusual sound,

The part number that solved my problem is 24405911.

It is known as Oil Pump front main gasket.

When one will replace it it will remove the timing belt, thus consider replace them together.

Oil in coolant most often comes from a leaking head gasket. You may want to perform a compression leak-down test to confirm.
