2003 2.3 liter duratec timing BELT OR CHAIN?!? INTERFERENCE OR NON?!?
 
Chains, not belts.
 
so im guessing with a chain thats its an interference motor then? ususally chain motors are interference.
 
Chain and interference. Also, if it is like the Focus 2.3, you cannot safely remove the crank pulley. It has no keyway, and will turn when the bolt is removed screwing up ignition and cam timing. If it turns too far, valves and pistons meet with disasterous results.:)shady
 
Chain and it is an interference engine.

An interference engine can be either have belt driven cam(s) or chain.
 
I'll say the same Chain & Interference.

Even rotating that engine backwards while working on it
is extreem badness.
