Thanks for the offer but they worked with me. I don't know what the service manual calls for but they said they put 6 quarts in and I am not sure if that is for a dry engine or if they filled the oil filter then added 6 quarts.
Anyway they verified I was consuming oil and replaced the valve cover, fogged the intake and put some sort of deflector in the oil pan. They again over filled my oil according to the dip stick but after 1300 miles on this oil change I have not consumed any oil!
