If you had a piston skirt broken off inside your engine, it would not be running as it would have immediately caused major internal damage.

The tapping sound you hear may be anything from simply low oil, to a worn out valve train components, but it is difficult to diagnose without hearing the noise.

I would recommend having an expert from YourMechanic come to your home to properly diagnose the noise coming from the engine and help you make an accurate repair.
