My concern is damage to the engine. My CPO runs out the end of next month and I do not want to have them do some minor repairs to find in 3 months I need a new engine or top end. The car was acting very slow/sluggish and I was getting alot of smoke out of the tailpipes. Once I had let the car sit for the day and then checked the oil and under the oil cap and saw alot of white milky goop. My heart sank. I check the oil regularly and had never seen this before.
