If my timing belt went on my 97 miata are my valves damaged?
Not unless you were running RPM's high enough to float your valves. And I've never heard of that happening on a Miata.
I've floated valves and collapsed a lifter. Took me several years, though. Stock 1.6 valvetrain, 8000 rpm redline. They start to float around 7800 or so
