What is your question?
I have 66000 miles, and loose one to one and a quater quarts of oil each 3-4 weeks, but cannot find any source of the leak. My oil and filter are changed every 3000 to 5000 miles. This car runs great. Any suggestions?

Oil rings have been an issue on some northstar engines like the one in your 2003 Cadillac Seville. There is a cleaning procedure that has some success. The service bulletin number is 02-06-01-009C.
