Got my car two weeks ago, '02 base model with 39k on the ticker. Had a few problems before I got it that were taken care of by Lund Cadillac in Phoenix (AC blender door actuator, upper radiator hose, compressor, leaking valve cover gasket). They did the full fluid exchange with a new battery as well. I drove the car 1300 miles back to Rapid City with no issues. GREAT drive. Great car. Put about 2k on it all together. This afternoon the CHECK ENGINE OIL shows up ok the DIC. I checked it. Just the tip of the dipstick was wet. I'm a habitual parking spot checker after backing out. It has never leaked on me. No leaks in the driveway or at work. I checked under the car and under the hood for leaks. Everything appears to be bone dry. I'm gonna throw a couple quarts in it tomorrow (not driving in the mean time, obviously) and do some troubleshooting. Searched old threads for some info and got some pointers so I'll be checking some of the common leak spots. Anything else besides the obvious?
