Some PT Cruisers run semi interference engines, meaning the piston and valves wont collide, but it is possible for the inlet and exhaust valves to interfere with each other and cause bent valve stems.

That "clunk" could have been the belt snapping and hitting the timing belt cover, only way to know for sure is to pull the cover and see.

As previously mentioned a compression tester will determine if you have hurt the valves.

When is the last time you had the timing belt replaced?

They should be replaced every 70,000 miles.

If the timing belt went you could be in for an expensive repair it can destroy your engine.

Can you see under the timing belt cover and if it is missing any teeth or if the belt is loose?

Most people don't know that many of the new engines use timing belts and that these need to be replaced as the miles get high. When the belt breaks the valves are no longer opening and closing so the engine will not run. What is even worse is if it is what is called an "interference engine" and the belt breaks. On these engines the clearance is so tight that when the valves get out of time with the pistons the pistons will impact the valves and destroy some of them and maybe even the piston face. If this is what has happened it will take major repair to fix the engine.

You can get a compression tester and check to see if there is any compression in the cylinders. If there is not then its a pretty good bet the belt is broken.

We had a diesel tractor if the timing was out by a hair the piston would hit the valves and bust the rocker arms.

I never thought about using a compression tester but yea that would work also.
