Im hearing a rattling noise under the truck and think that it may need a timing chain . I have 96000 miles on truck and its never been changed
I started it up and it ran for about ten min and then I went to put ot in drive and the engine shut off . I started it back then that's when I heard it clanking or banging of something under the hood up at the front of the motor.
Rattling noise coming from motor sounds more of a flutter then a knock Ford dealership said it was the timing but not I dug is a timing chain cassette
It's making a rattle noise & the timing belt was changed a couple days ago but it still makes the rattle noise
Went through total of 3. yes 3. 2006 it caused a valve to set on top of piston. Got a rebuilt motor it ran 1 year. the only way shop would cover said problem, under warranty. was put on(all) mufflers. 3 catalytic mufflers, do to possible back pressure here I am with a great truck with bad engineers or money grabbing (?). So next, I hope that show will come that fixes problems with one loved truck. Put a mustang motor, trans & ecu. make my wife her ford adrenaline 2002. Problem FREE
