So I've got this noise coming from what I believe to be the pedals...

My pedals are originals from 1975, and are bent to pieces (I believe I'll be getting some newer ones soon), but I was wondering if the noise I'm hearing is possibly coming from the pedals.

Sometimes, I can feel a little kick in the pedal when I'm biking, so I really do believe the noise has to be coming from them, but is it plausible?
