    Piston slap on higher mileage engines at cold start.

    Timing chains and guides are close to end of life. Check the heads for a "blue stripe" on the intake port side. This will indicate 9 thread spark plug TSB revised heads. The more common 4 thread tend to let the plugs fly out. It should have the 9 thread heads. Other than that, spun bearings are common from people beating on them.
