# Service bulletin CSR 516

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Some 2018\-2020 F\-150 vehicles equipped with a 2.7L EcoBoost may exhibit an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTCs\) P0420 and/or P0430 stored in the powertrain control module \(PCM\). This may be due to calibration and controls sensitivity.
- [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.
- [TSB 22\-2248](/bulletins/10251453.md), 2024-03-07, Service bulletin: ENGINE AND ENGINE COOLING. This article supersedes TSB 22\-2201 to update the Service Procedure and Parts List. Some 2015\-2019 F\-Super Duty and 2016\-2019 F\-650/F\-750 vehicles equipped with a 6.7L engine may exhibit an oil leak from the oil filter, crankcase vent oil separator, oil cooler, or upper/lower oil pan. This may be due to the mating surfaces of the upper oil pan and the engine block or to a clogged crankcase vent oil separator.
- [SSM 51691](/bulletins/10237789.md), 2023-06-16, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; POWER TRAIN. 2011\-2023 F\-Super Duty and 2016\-2024 F\-650/F\-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C \(80°F\) and may increase to 1200 RPM at \-40 °C \(\-40°F\). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take\-off \(PTO\) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages.
- [TSB 23\-2143](/bulletins/10236037.md), 2023-05-31, Service bulletin: ENGINE AND ENGINE COOLING; POWER TRAIN. Some 2017\-2020 F\-150 and 2018\-2020 Expedition/Navigator vehicles built on or before 30\-Nov\-2019 and equipped with a 3.5L EcoBoost engine may exhibit a ticking/tapping or rattle type noise from the top front cover area of the engine on initial start\-up after a cold soak of 6 hours or more that may last for 2\-5 seconds. Some vehicles may also exhibit an intermittent condition with no auto restart during auto\-start\-stop operation with or without diagnostic trouble code \(DTC\) P164C present in the powertrain control module \(PCM\). This may be due to a worn variable camshaft timing \(VCT\) unit. To correct the condition, follow the Service Procedure to replace the VCT units.
