The hazard
On certain vehicles equipped with a Caterpillar engine, the Variable Valve Actuation oil line (VVA line) used on 6 cylinder, 15L turbocharged and air-to-air aftercooled diesel engines may wear against the sharp edge of the cylinder head if not oriented correctly. Oil line wear may cause an oil leak and a potential fire hazard. Correction: Dealers will inspect and, if required, replace the VVA line.
