I usually associate a tick with the valvetrain.
Some guys have had their engines torn down and the rod and main bearings look fine.
Some guys theorize it's cause by oil cavitation in the oil pump or rod/main bearings ... but I have a hard time buying into that. If it was cavitation in the oil pump, then why hasn't Ford redesigned the oil pump since 2011 when this ticking noise started in the Coyote engines ... but instead replace short/long blocks.
I read some more in that forum. The threads are long on this subject. A lot of speculation on what it is but piston slap keeps coming up as a common answer.
This is not something I would be happy with. New engines should not be ticking or knocking right off the showroom floor. I hope Ford finds the cause.
The "piston slap" is something that came along with the 2018+ Gen3 Coyote ... theory is due the the plasma sprayed cylinder liners like in the 5.2L GT350s.
The BBQ/typewriter tick is a different animal, and can happen in Coyote engines since 2011. So the 2018+ Coyote can have two different engine noised going on.
Yeah, there must be 100 threads on the ticking noises ... and some of the theories are wild. What's even more amazing is why hasn't Ford fixed the issue, I'm sure them must know what it is caused by.
This because there are hundreds of forms from nearly every manufacturer and there are threads complaining about tick.
