Oil leak found at seal, dripping oil. Not very much. Engine oil shows full.
Found engine not mounted properly when purchased. Found after replacing oil seal twice within first 6 months of ownership. Now the seal is leaking. Is this a factory defect. Of course its not long after the warranty is up.
What can be done.

Upon physically checking oil level in my 2010 Buick Lucerne 3.9L, V6 engine, with 25% oil life displyed on instrument panel between oil changes, none showed up on stick. Added a quart and level went to approximately 1/8 of an inch on stick...added another and it went to the mark just below the full mark. Took car to local dealer where car was purchased for an oil consumption test. I was told that there is an indication of an oil leak, but I assured the technician that there was no sign of oil leak on my cement garage floor. Changed oil and returned after 1,047 miles. Oil consuption test revealed .25/quart used and engine was again tested for an oil leak. Dye was added to oil and leak was observed at front of engine with a black light while engine was running. Crankshaft seal was replaced and was told that the problem was resolved. We shall see! Surely hope this new engine doesn't burn 2 quarts of oil in 4500 miles!
