All different theories on this .
I have never liked the drain back method. I dunno....if you are too cheap to replace the oil with fresh new....get a new hobby. If your car has that much blow by that you are worried about engine oil level, something is wrong.
Open breather method is somewhat effective and easy to do. Many people do this. I like the exhaust method to aid in the excavation of the vapors.
