I had my timing chain guide to break on 1997 ford explorer sport and now truck is missing. Do you think something else broke in it as well?

A broken timing chain guide in your 1997 Ford Explorer Sport is a serious issue, and yes, it's highly likely that other damage occurred. When the guide breaks, the timing chain can become misaligned, causing the valves to collide with the pistons. This is known as valve-to-piston interference and can result in:

* Bent or broken valves: This is the most common consequence.

* Damaged pistons: The force of the collision can damage or even crack pistons.

* Damaged cylinder head: The impact can crack or warp the cylinder head.

* Damaged crankshaft: In severe cases, the crankshaft can be damaged.

The "missing" engine performance you describe is a strong indicator of significant internal damage. It's unlikely the engine will run smoothly, if at all, without repairs.

You absolutely should NOT attempt to start the engine again. Further damage is almost guaranteed.

You'll need a thorough inspection by a mechanic to determine the extent of the damage. They'll likely need to remove the cylinder head to assess the condition of the valves, pistons, and cylinder head itself. The repair could range from relatively minor (replacing the guide and some valves) to a complete engine rebuild or even replacement. The cost will depend on the extent of the damage.
