My 2007 Cayman S has 195,000 miles. It has started using more than a quart of oil in 500 miles. My thoughts are that this could be a valve seal or valve guide issue. I'm thinking of pulling the heads and having them rebuilt. When I inquired about this with a local shop they indicated that doing this without redoing the bottom end of the engine would be a waste of money since redoing the heads will put added stress on the rest of the engine. Any thoughts?
