I have a 1.6 8v Astra , the oil is blowing or being sucked into the air filter from the camshaft cover.
The oil level has been checked and is correct.
Where is the oil separator or ventilation valve is there is one.

Modern engines are designed to consume (burn) any oil from the crankcase ventilation system, rather than dump it to road or atmosphere.

As engines get older and/or use cheaper oil the amount of oil mist in the crank fumes increases - this will be noticeable in the air cleaner and throttle body - you just need to keep the parts clean, particularly the throttle body.

Make sure that the oil level is not overfilled. Check level first thing in the morning before it is driven.

Clean out all of the crankcase breather hoses.

I think that there is an oil separator in the cam cover, remove cover and clean it out by soaking it in white spirit/ petrol.

Don't forgot to include the small bore breather pipes too if any.

Hi at the outside it could be piston rings pressurising the crank case after cleaning everything out turn the airfilter and clean out the airbox and monitor the oil spray if excessive over a few days you might have the problem i mentioned but if you get virtually nothing then don't worry
regards
