Lower end engine noise

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The crankshaft, connecting rod(s) and bearings are common sources of lower end engine noise (tick/tap or typewriter noise). This noise should be considered characteristic as it is not detrimental to engine durability. The 6.7L diesel includes design improvements to reduce overall inherent diesel engine noise. These sound reductions improvements enable certain characteristic noises to be more easily heard. Lower end noises can be determined by using the oil pan or cylinder block lug bosses. If the noise is loudest from these areas then the noise is lower end. If an engine noise is isolated to the lower end, some disassembly of the engine may be required to inspect for damage or wear. Using the incorrect engine oil can negatively impact the level of noise. For additional information, refer to Engine for System Overview and Oil Requirements .
