problem #2

Feb 282024

DeVille

  • Automatic transmission
  • 100,200 miles

The car went from a drop or two while sitting in the driveway for a couple of days, to an awful mess as it now requires me to add a quart of oil every 2-3 weeks! Cadillac says "yeah that happens" and the apparent solution is to tear down the engine to replace the gasket between the aluminum head and the iron block (3-5k); THEN they tell me that after about 6 months it will "just go back to doing it". The oil is leaking in such a way that the interior smells awful for the first 20-30 minutes until the oil burns off of whatever it's leaking on AND there is smoke (light) coming out of the engine compartment.

DeVille

Oil leaks out of my engine and creates an unsightly mess in my garage. It also requires me to add oil between oil changes.
