Yes, the BBQ tick has been a characteristic of the Coyote since it came out in 2011 (Gen 1 Coyote). Back then, Ford told dealers to add Motorcraft XL-15 friction modifier, which typically cured the ticking. Motorcraft XL-15 is no longer available, so lots of Mustang guys with the tick add LiquiMoly Ceratec (also a friction modifier), which also typically cures the tick. Some guys even report Ceratec curing the tick when added at 1/4 the recommended add ratio, which would be only 150 cc (0.16 qt) in 8 qts of oil - thats only 2%.
The ticking is in the bottom end, and one theory is that if the friction level is high, then that may be causing the big end of the rods to "dance" side-to-side on the crank journal on some engines - maybe ones with the rod side cleatance on the large end of tolorance. As soon as you add a friction modifier, the tick disappears almost instantly.
Another symptom that supports the friction level theory is the fact that the tick can slowly disappear as the miles get put on the oil, then the tick will be back almost instantly with an oil change. This tells me that the friction level slowly decreases from an anti-friction tribofilm forming on parts during an oil run, and when the oil is changed the new oil strips most of that AF tribofilm off, and the friction increasrs again and the tick is back. The tick sure seems to be associated with the friction level between moving parts.
