This may be due to a worn variable cam timing (VCT) unit. A TSB is expected to be published 4th quarter of 2019. In the interim, replace all 4 VCT units and update the powertrain control module (PCM) calibration. Do not replace timing chains, tensioners, guides or other timing related components unless inspection clearly identifies a concern. Refer to the Workshop Manual (WSM), Section 303-01. Claim the labor required to replace VCTs using published labor operations and PCM programming using M-time. Monitor OASIS for updates.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10165685-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10165685-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10165685","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2017,"year_to":2018,"match":"exact","vehicle_ids":["2017_ford_expedition","2018_ford_expedition"]},{"make":"FORD","model":"F-150","year_from":2017,"year_to":2018,"match":"exact","vehicle_ids":["2017_ford_f-150","2018_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
