the problem chain is the primary one, which runs from the crank to a jackshaft, and is located at the front center of the engine. accelerate with a cold engine and listen around 2500 RPM for a rattling sound. if you hear it, your crappy plastic tensioner has worn down, allowing the chain to get slack and slap against things inside the engine.

how much of a problem? worst case scenario, it gets too much slack, jumps off the teeth on one of the sprockets, and the timing gets screwed up, sending pistons into the valvetrain, and the engine to the trash heap. I have only heard of a few engines self destructing, though, and many have driven with it for miles and miles without it taking a dump.

to fix it, the engine front cover has to come off, and you replace the tensioner. but Ford has no timing marks on this engine, so you have to use their proprietary tools to retime the engine, which can run about $150. the repair parts kit is about the same price. you'd probably have to call your dealer to get an estimate with labor time included, the ones I have gotten vary wildly.

its covered in service bulletin 04-15-4

its is a big deal. your engine is an interference engine. if the timing chain breaks the engine is trashed. mine broke on me in traffic before i got to the tunnel. the engine has 3 chains on it. 2 in the front and 1 in the back. the engine has to be removed to get to the back one.
