## NHTSA's summary

Some 2016 F\-150 vehicles equipped with a 5.0L engine and built on 13\-Jan\-2016 and through 16\-Jul\-2016 may exhibit an audible knock noise from the engine only after the engine is at normal operating temperature and between 1500 and 2500 engine RPMs If cylinder \#5 is canceled and the noise is no longer present, consider the noise a characteristic and do not attempt any repairs. Engineering has determined there are no long term durability concerns.

## Other bulletins for the same vehicles and component

- [TSB 24\-2098](/bulletins/10252672.md), 2024-04-04, Service bulletin: ENGINE AND ENGINE COOLING. This article supersedes TSB 23\-2330 to update the Parts List. Some 2015\-2017 F\-150 vehicles equipped with a 2.7L EcoBoost engine may exhibit an oil leak from the oil pan RTV seal. This may be due to various concerns with the oil pan. To correct the condition, follow the Service Procedure to replace the oil pan with the later style oil pan.
- [SSM 52335](/bulletins/10251952.md), 2024-03-20, Service bulletin: ENGINE AND ENGINE COOLING. For 2015\-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual \(WSM\), Section 303\-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.
- [SSM 52334](/bulletins/10251951.md), 2024-03-20, Service bulletin: ENGINE AND ENGINE COOLING. Some 2011\-2024 Mustang and F\-150 vehicles equipped with a 5.0L engine may exhibit a tick tap and/or typewriter ticking noise at idle after an engine oil change. It is often referred to as typewriter noise because of its similarity to the sound of a mechanical typewriter. The noise in question may be heard on some engines when engine temperatures reach 150°F \(65°C\) or higher and engine speed is at idle up to approximately 1700 RPM. It can typically be heard at the front wheel well and is often isolated to the transmission bell housing or oil pan area. The typewriter noise tick rate can be faster or slower and is not detrimental to the engine function or durability and has no short or long term effects on the engine. This an operating characteristic of the 5.0L engine and no repairs should be attempted. This information along with an example audio clip has been added to the WSM Section 303\-00 Engine System General Information \> Diagnosis and Testing \> Engine \> PPT F \> Step F2.
