Engine got a knocking cold start, silint when hot

It has developed a clicking engine noise on a cold start. After the car has warmed up, the sound goes away. ... Clicking or a sharp tapping from the valve cover on top of the engine would point to a valve train noise. A dull tapping or slapping sound from the side of the engine block would point more toward piston slap.4 Nov 2011

Cold-start engine clicking is a nuisance, not a disaster -

What causes tapping valves?

If you hear the valves, usually they are worn out and/or not getting enough oil. They are self-adjusting so they are supposed to stay in place. The valve train is the last thing in the engine to get oil from the pump.

2002 Concorde valves tapping

How long has it been from oil change. Have you checked Oil pressure? If filter is old and dirty fluid needs to warm to be thin enough to get enough volume to valve train. If oil pump is getting weak it will not pump sufficient fluid to valves at low RPM. First change oil and filter. After that make sure pressure is in spec's.

Valve train tapping?

The 6.0 engine had an issue with piston to bore clearances, from the factory these clearances were excessive. It is reffered to as "piston slap". This condition is known by GM, but most dealers say it's normal. It can be as slight as an annoying tick, to a clearly audible clacking noise. Unfortunately the condition was under played by GM, and there are many folks who haven't been able to get help with their trucks. I own an '03 Silverado w/6.0, and hear this noise everytime I start my truck. I deal with it, because I'm a mechanic and figure I'll be able to fix it if I need to. Research more online about this condition. I've found many websites that relate to this issue (Google: 6.0 piston slap) I hope this helps.
