Haz Posted May 27, 2023 Report Share Posted May 27, 2023 SSM 51665 - 2021-2023 Various Vehicles - 2.7L/3.0L Engines - Upper Engine Thump/Knock Noise Some 2021-2023 Ford and Lincoln vehicles equipped with a 2.7L or 3.0L engine may exhibit an upper engine thump/knock noise coming from the left cylinder head. This condition is most noticeable at idle and may lessen at higher engine speed or while driving. This condition does not affect vehicle durability and will not get worse over time. Use a stethoscope or chassis ears and listen just behind the left cylinder head intake VCT solenoid on the cam cover to determine if the thump/knock noise is coming from the cylinder head/camshaft. The left cylinder head and the camshaft roller followers are available as service parts. 1 Quote Link to comment Share on other sites More sharing options...
