Timing chain broke on 2002 Chevrolet Cavalier LS causing catostrophic engine failure. Automobile only has 70,000 miles on a well maintained motor. Gm installed faulty oil nozzle as well as timing chain tensioner in motor originally but refuses responsibility even though checked at gm certified service center 4 months prior complaining of timing symptoms. No repair has been done at this time. After much research it seems that this is a common problem in all vehicles from 2002 and 2003 that have 2. 2l ecotec motors.
