GENERAL MOTORS recall on REGAL, GRAND PRIX, and IMPALA models

On certain vehicles equipped with a 3.8L engine, degradation of the front rocker cover gasket may result in eventual oil seepage. Under hard braking, drops of engine oil may be deposited on the exhaust manifold. If the manifold is hot enough and the oil runs below the heat shield, it may ignite into a small flame and, in some instances, the fire may spread to the plastic spark plug wire channel and beyond. An under-hood fire could result in injury and/or property damage. Correction: Dealers will remove the spark plug wire retention channel at the front of the engine and install two new-revised spark plug wire retainers. For vehicles with the 3.8L V6 Supercharged engine (RPO L67), dealers will also replace the front (left hand) rocker cover gasket. Note: This recall is an expansion of recalls 2008-081 and 2009-105.
