Timing Belt looks bad, is the motor cooked? S90-V90 1997

Yesterday I noticed that my power steering went dead and my alternator light came on. I pulled into a gas station and found my serpentine belt was off. I started the motor and got what I would describe is a rattling sound, than it quit. It was pouring so I called AAA and got a tow home. Today it wouldn't start, so I pulled the timing belt cover. The timing belt is quite slack, but does not appear broken. The cams do not appear to turn (I'm on my own, so I can't watch. I crank from in the car and then look at the position of the cams). This is the 6 cylinder but I assume it is "interference". Any quick way tell if the valves are bent? The "rattling sound" worries me.

PS The crank pulley seems to have pulled out and exposed a good deal of spline. I had never really looked at that before.

Hope you live in an area with a good supply of 960/S&V90 parts cars. Pick one where you can witness the engine run or one that has damage indicating engine was running fine up until the car hit something.

Breaking a timing belt on this car is bad news. Valves are likely bent. If you want to fix it, the cheapest thing is probably to buy a used head.

Did the broken serpentine belt get sucked into the timing belt? There is a guard which is supposed to prevent that from happening but they sometimes are not installed. That can be very bad...

You can bump the starter under the hood by jumping the starter relay. That said, it sounds like the valves are toast. Pull a plug and stick a dowel or something with a rubber tip down the hole and if you feel no compression at all you can confirm this.
