  1. Thanks for the replys. I was going to take it back to my mechanic tomorrow but we are getting snowed on here in OHIO like crazy,so i cancelled until next week. He wants to put dye in the oil and drive it for a while and then check it with a UV light for leaks. I have been doing the WOT procedure, but not 10 times in a row.Maybe that is part of the problem.
  2. I own a 2001 SLS with 52000 miles. About a year or so ago it started using a quart of oil every 400 to 500 miles. It was still under warranty and the cadillac dealer claimed that they decarboned the engine.That did no good.I have tried the WOT many times and that does not help. I am now taking it to a mechanic who used to work for cadillac. He changed the oil,filter and all of the rubber hoses going to the PCV valve.HE put in 10w-40w oil, which helped a little. The oil consumption is now about 600 miles per quart.Tha car does not smoke when started or while driving. The main problem is that there is no oil on the top or bottom of the engine,but the insulation under the hood is saturated with OIL. Has anybody else had this problem?
