Why GMAC northstar engines leak oil, between 1994-2005? Can we DO CLASS-ACTION? on 2005 Cadillac DeVille

ENGINE APPEARS TO BE GOOD, EXCEPT IT LEAKS OIL, CONTINIALLY. MINE HAS GONE FROM FEW DRIPS AT 40,000 TO NOW OVER 100K, 2-3 QUARTS ADDED BETWEEN OIL CHANGES. cAN`T WE DO SOMETHING OR ANYTHING BESIDE COMPLAINING. GM MANAGEMENT HAS IGNORED ME, THOUGH I HAVE WRITTEN MANY LETTERS, SOME CERTIFIED, NOTHING, BUT USUAL STUFF.
