Changed valve cover gasket, valve seals, spark plugs and wire. Still oil leaks on back 2 spark plugs and runs rough in morning. Pressure tested great in all plugs/cylinder. And almost everything else has been replaced!

Do you

Which motor?

Did you feel the valve guides when replacing the seals? If there is lateral play, it will continue to use oil. Otherwise, you may have bad oil rings on the pistons. A wet and dry compression test will confirm.
