Can a small rattling sound be a sign of bad apex seals?

Can a small rattling sound be a sign of bad apex seals?

Last month I bought an 88 FC vert. Which has been my dream car for years. It's at the 75k mile mark and I know 80k is normally when apex seals fail. The best way I can describe what I hear from the engine is a small rattling sound. If anyone has any ideas that'd be much appreciated. Thanks

post a vid so we can hear it. never heard loosing apex seals at 80k. i've seen original engines with well over 200k and i have nearly that much on my engine i built back in the early 90s.

Tried to film it. It's such a quiet sound that the camera doesn't pick it up

I will go out on a limb and say that it's not an apex seal rattling. You would need a compression text to rule figure out if you've lost seals. Rattling could be a pulley bearing or something loose, airpump or something.
