How do you know if a have a bent mechanism on my trumpet?
If you have a bent valve slide, or valve, or valve casing, they usually wont move. Valve's and valve casings would prevent the valves from moving, while bent valve slides wont easily pull out. If you suspect a bent valve, valve casing, or slide, try cleaning and oiling it first, valves and slides can become stuck with the lack of valve oil or slide grease.

You don't fix it, you replace it. Replace the belt according to the schedule in your owner's manual. If it breaks and your engine is an interference engine, you will 95% of the time have damage. You will know the extent of the damage when the engine is torn down. ---------- Saturns do not have a timing belt, they have a chain, as stated in the question.

What causes backfires and low compression in an engine?
Sounds like the valves are not closing properly. Something in the valve train is damaged. Could be a bent or broken valve, broken valve spring, broken or bent rocker arm, bent push rod, etc. Low compression combined with back firing thru intake would indicate a damaged intake valve component and back firing thru the exhaust would indicate a damaged exhaust valve.
