Cam phasers and oil changes 2004 and up.
Something from "Engine Builder" I thought was interesting. I bet this happens quite a bit. - Then they get noisy.
Tech Tips for 2004 and Up Ford F-150 Engines
Watch out when you change the oil on one of these three-valve engines found on 2004-and-up F-Series. The cam sprockets are variable timing sprockets called phasers. The cam phasers have six metal tabs that stick out from the sides, which excite the cam sensors to tell the PCM the exact position of the camshaft. The right-hand phaser is located directly under the oil filler neck, and can be viewed by looking down the neck. Occasionally, a careless oil change tech will leave the oil gun in the filler neck and start the engine. The tabs are then bent and broken from the phaser. This causes anything from just a check engine light with a cam sensor code to a severe loss of power from the PCM over-advancing the camshaft.
