Oil vapor from -oil filler cap?
How much oil vapor is normal to see coming out the oil filler cap? That is while cap is removed and engine is hot and running?
Have not looked at this in years, so just checking.

Know you are rightly concerned about the health of your fresh long-block.
Once the rings and cylinder walls have become friendly with each other, figure on no more than one or two CFM of positive displacement at idle. The ‘mist’ you’re witnessing at the filler cap is normal discharge from under our cam/valve cover.
If you haven’t already done so, fit a catch can in the PCV system to help keep spent crankcase hydrocarbons from migrating into the intake tract.
