I am the OP on this thread. Right on time, after my first 1,000 mile change the infamous barbecue tick has started. Here are two videos of it.
I hear Ceratec does work, but a guy on Mustang6G did an experiment that it fell out of suspension after sitting for a week and even left a bunch of sludgy residue at the bottom of his experiment jar. So I'm a bit weary of running an additive. Gonna switch to 0W40 next oil change and see what happens. What comforts me is every 2018-2022 owner GT I've seen at car meets has the same sound. And the common denominator? Ours all started after the first oil change. So I bet Ford gives a special additive to it in the factory fill 5W30 to make it quiet. UOA from factory fill show high moly and boron so I am trying to find a full synthetic 0W40 or 5W40 that will be higher in those two ingredients.
My 2017 had the tick. Ceratec does work, that tick will go away instantly. Why? I don't know. I also noticed that Pennzoil Ultra Platinum 5w30 greatly subdued the noise, nearly eliminating it in my case. Since oil brand and additives influenced the noise I decided there was not a real issue to worry about.
I track my car. I ended up cracking the ring land on the #8 piston and lost compression with 19,XYZ miles (my fault). I rebuilt the engine in my garage. Everything inside was immaculate except for the piston that had cracked and scored the bore. All of the bearings were perfect, I could still see the ink stamps on the bearing surface. The crank was perfect and the rod side/side clearance was in spec. Didn't measure main or connecting rod bearing clearances since it all looked perfect and I wasn't reusing the stock rods anyways. Oil pump and valve train was perfect. Had the block lined honed and bored 0.010" over and rebuilt with Manley rods and Wiseco pistons. I replaced everything that could be considered consumable except the primary chain guides because they were fine, and the secondary chain tensioners because the ones I ordered were wrong and I got too impatient to wait for the correct ones. It hasn't made the BBQ tick noise once since the rebuild. Now I just have minor piston slap until the forged pistons warm up.
I'm just stating all of this to say that I saw absolutely nothing that indicated there was an issue with the engine. Yeah it's a sample of 1. Dump the Ceratec in if you want it to be quiet.
