Had the identical problem. Nice clean engine oil for sure. Fine spray on window followed by light spray on both sides of engine bay. Some oil collected in channel on rear facing outside corners of valve covers. Checked valve cover breathers (negative), went through everything under and in front of engine (all bone dry). Problem disappeared after a few drives. Only thing I can think of that makes sense would be new valve cover gaskets seating. Could it have been overfilled with oil? What else?
