Did yours sound like a engine knock or " valve tap"?

Sounded like exhaust tick.. I had a tap but it went away when I took the engine apart and cleaned everything..... knock and tap and also slap are different things. Knock comes from bearings and sounds like it implies. Tap comes from the valvetrain and sounds like it implies, and slap is from the piston and sounds like the name implies.
