Were you low on oil?
You might have had a weak lifter or hearing chain noise
All hard to tell without knowing what it sounded like.

Re-filled with Rotella 5W40 (same as before; last oil change 5 months / 1 Kmi ago) and started it. Smooth idle, no noises.
I haven't checked for noises above-idle yet (all engine covers are off, and the motor gets quite loud when you go >1500 rpm).
I guess I'll look at the spark plugs tomorrow, just in case.
Is it possible for a valve spring to be broken, and you can't hear it at idle?
