Yes caps can be noisy but typically only if they are old and dried out, or other such damage, try the old trick of putting a long solid piece of plastic on each component and sticking it to your ear, works for well for isolating physical sounds in an engine, may be worth a shot here... Torroids will sing under the right circumstances, and sometimes it can be difficult to trach low feq sounds...
