How can you tell if a valve is bent or sticking on 93 sonoma?

To determine if a valve is bent or sticking on a 1993 Sonoma, listen for unusual engine noises such as ticking or tapping sounds, which may indicate a problem. Additionally, perform a compression test; low compression in one or more cylinders could suggest a bent valve. Lastly, inspect the valve train components for signs of wear or damage and check for any sticking by manually rotating the engine and observing the valve movement.
