This noise may be caused by a cracked piston skirt. The noise can be isolated to a cylinder using a stethoscope or other suitable listening device. Canceling the affected cylinder will reduce or eliminate the noise. If the noise is isolated to a specific cylinder, it is recommended to replace the short block. If the noise cannot be isolated using the methods described, refer to the Workshop Manual (WSM) for diagnosis. A cracked piston skirt does not result in metal contamination of the engine or any related cylinder head damage. Short block replacement does not require prior approval.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10143100-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10143100-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10143100","components":[{"id":"engine","name":"Engine","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2015,"year_to":2017,"match":"exact","vehicle_ids":["2015_ford_expedition","2016_ford_expedition","2017_ford_expedition"]},{"make":"FORD","model":"F-150","year_from":2013,"year_to":2018,"match":"exact","vehicle_ids":["2013_ford_f-150","2014_ford_f-150","2015_ford_f-150","2016_ford_f-150","2017_ford_f-150","2018_ford_f-150"]},{"make":"FORD","model":"TRANSIT","year_from":2015,"year_to":2018,"match":"exact","vehicle_ids":["2015_ford_transit","2016_ford_transit","2017_ford_transit","2018_ford_transit"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2015,"year_to":2017,"match":"exact","vehicle_ids":["2015_lincoln_navigator","2016_lincoln_navigator","2017_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
