2014 Knocker
I recently bought a new truck and reported a bottom end knock- at 1,200 miles. Most noticeable just above idle,700rpm,under load. I did a oil change at 1200 miles and dealer inspected oil filter and said was OK. Ford engineer had tech remove the left belt and I was told the knock was gone???? Then engineer had tech verify noise in other trucks on lot. They said they heard it in 7 other trucks!! At that time Ford said no repairs to be made as noise is ,"NORMAL", operation! Hard to believe as I was in auto business for 38 years, now retired. Thats possibly why I hear this knock and it haunts me! This was to be my last truck.
Anyway do you think it could be a water pump issue? Someone else said they had noise issues with water pumps and possibly torque converters? I asked the tech to shutoff injectors and listen but they didn't because they heard same noise in other trucks. This knock,knock,knock when I drive slow or pull into the garage haunts me
Would appreciate your ideas/ thoughts? Also please keep an eye out for a TSB that may apply. If so many 5.0's do this, they might explain or address in a TSB. Sorry I was so long

Knocking and oil eating are the Achilles heel of the 5.0

Not sure but there have been a lot of people with Cali emissions complaining about the same thing. I would stab a guess at a belt driven air injection pump or similar because Ford says it's a normal characteristic.
They all say the knock goes away with the FEAD belt removed eliminating base engine and narrowing it to an engine accessory.
