I have 2 F150s with the 5.4 engine, one is a 07 with 68k on it, and one is a 08 with 215k. Have always used motorcraft fl820s filters but switched it up on the last oil change to the carquest premium 85372 filter. After the oil change the 08 had terrible chain rattle on every startup. After about 500 miles I finally pulled the carquest filter and replaced with a motorcraft filter. The chain rattle went away. The 07 starts fine every time with no issues. Is it possible I just got a dud filter? I plan on cutting it open and will post pics.
