Help to identify piston slap, MY21 Mach1

[Esset]

Hi folks,

MY21, 13k miles, oil change every 4k miles. Knocking sound is more eminent for cold engine, tent to be more suble for CHT over 210F. Seems to be located at passenger side of motor, recording taken also from that spot.

Is that it?

It sounds like a Coyote idling.

What, no random BBQ/typewriter tick?

I agree with above, sounds just like a Coyote idling. Passenger side has the DI pump, they are VERY noisy. Mine sound exactly the same. 15k miles, Oil changed every 5k. 5w30 Liquimoly Molygen oil.

Sounds like it should to me. It certainly doesn't sound like piston slap.

Sounds pretty quiet for a Coyote.
That’s normal.
