PACCAR Incorporated (PACCAR) is recalling certain model year 2010-2016 Kenworth T440, T800, and W900 trucks manufactured August 31, 2009, to April 20, 2015, and 2008-2015 Peterbilt 320, 337, 348, 365, 382, and 384 trucks manufactured July 27, 2007, to April 28, 2015, and equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
PACCAR Incorporated (PACCAR) is recalling certain model year 2009-2015 Peterbilt 320, 365, 367, 388, and 389 trucks manufactured July 21, 2008, to February 28, 2014. The front axle tie rod end clamp bolts may be improperly torqued.
