Certain underhood fires may be caused by drops of engine oil, from seepage or spillage, being deposited on the exhaust manifold through hard braking. 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.
GM is recalling 207,542 MY 1997-2003 Buick Regal and Pontiac Grand Prix vehicles equipped with a 3.8L supercharged V-6 engine. These vehicles have higher front rocker cover gasket temperatures, creating the potential for earlier degradation of the front rocker cover gasket and eventual oil seepage.
Dealers will replace the engine's front valve cover and front-valve-cover gasket with new parts of an improved design and remove the engine's plastic cover and plastic oil-fill-tube extension, along with the 1-3-5 spark plug wire retainers, free of charge. The recall is expected to begin during May 2016., free of charge. The recall is expected to begin during May 2016. Until the remedy is completed, GM strongly recommends that owners observe the following important precautions (1) that owners do not park their vehicle in a garage, car port, or other structure; (2) if owners notice a burning odor, they should have their dealer inspect the vehicle. The dealer will inspect the vehicle without charge; (3) use premium fuel (91 octane or higher) in the vehicle as recommended in the vehicle's owner manual. Owners may contact Buick at 1-866-608-8080 or Pontiac at 1-800-620-7668, or through their website at www.gmownercenter.com>www.gmownercenter.com.
