Timing chain on the 2.3?

If I undestand correctly the 2.3 PZEV is equipped with a timing chain?

I would say the change is for the better, well as in reliability issues. I know from experience a busted timing belt can ruin an engine quick. I love my PZEV.

I agree completely! I did not intend to sound like I preferred a timing belt. They can be fairly expensive to replace. Having the timing chain eliminates one costly maintenance issue during the life of the car.

That is very true. The reason I don't like the belt is because if you ever do bust it, then you can have tons of problems, such as the piston hitting the valves.

Hold on, folks. There are two kinds of engines with timing belts: intereference, and non-intereference. If you happen to be talking about an intereference engine, then you WILL have tons of problems, specifically the pistons hitting the valves. There is no maybe about it. Then again, if it is a non-intereference engine, the pistons and valves cannot hit each other. As it turns out, the Zetec is non-intereference, so the only real worry is getting stranded on the side of the road if a timing belt breaks. The only time there might be serious trouble with a Zetec is if you have made any changes to increase compression ratio, or if you are using a higher-lift cam. Now, the Duratec is a different story. It is an intereference engine. We are thankful to have the greater reliability of the timing chain.

The duratec is an interference engine.

He knew that, mentioned it right near the last sentence. So basically ours is a metal chain as opposed to the more "wearable" rubber belt like the serpentine or something? Sounds like a good deal... where is this in our engine by the way?

Well, the cams are under the valve cover, so sure, a portion of the timing chain must be there too. It's not the majority of the chain. The whole rest of it lives under the "front cover" of the engine, since the timing chain is driven by a sprocket on the crankshaft internally, just before the cranksaft emerges from the front of the engine to drive the accessory drive pulley.
