Hey all,
I came across a thread here on Mustang6g posted awhile back that might help put some new 2018 owners or prospective owners mind's to rest on the rattle issue (Not BBQ tick) that seems to be present on a lot of 18 GT's (including my own.) Being the Gen3 Coyote uses the spray-in liners like the GT350, I would say its probably along the same lines as what ford has outlined below about the GT350:
"OASIS 2888-
Some 2016 GT350 Mustangs might exhibit Piston Rattle from Idle to 3000 RPM
Some 2016 Mustang GT350 equipped with the 5.2L engine may exhibit a rattle or rapping type sound during cold operation at light loads and speeds from idle-3000 rpm. The noise will be most noticeable during light acceleration in the 1500-3000 RPM range and may also be noticeable in the 800-1200 RPM range with neutral throttle blips. This sound is caused by the piston motion in the cylinder bore. This is an inherent characteristic of the forged aluminum pistons utilized in this high performance engine. Once the engine reaches operating temperature the noise will diminish, although it may still be noticeable even when fully warm. There are no durability concerns with this sound."
As stated above, on my 2018, the rattle does almost completely go away when the oil temp is at its normal operating temp. Hope this helps guys!
edit: Gen 3 doesn't have forged pistons
