    Right when I changed mine for the first time 2200, I wonder if the dealers are adding something to the vehicles? Mine was sitting in the show room floor, did not start it or test drive that particular car before purchase. So so odd that it happens to many right after an oil change.

    This is my car exactly. I can hear it cold with windows down sitting in drivers seat 47 deg F. Then by the time home in garage not there. Alex has to learn to disable seatbelt alarm ha! My 2016 did not have this. Also I wonder if he has the "diesel" rattle up around 2k-2.5k rpm slight throttle? Or is that the same thing?

    I added a bottle of Ceratec this morning before a Sunday drive... Drove for an an hour or so without stopping so it was fully mixed in with the 5w-30 Mobile 1. Ran the car to redline, through 3rd gear, a couple of times also. Typewriter or BBQ tick appears to be gone. Have not heard any ticking at all since. Let the car sit for an hour after driving, restarted expecting to hear the tick and nothing. Engine seems to be quieter all around. My thoughts on this are the noise is either hydraulic lash adjuster, timing chain tensioner or oil pump cavitation related. I do not believe this is rod knock, main bearing noise or piston slap. With that being said, what is this additive doing to quiet the ticking noise? Secondly, why has Ford not figured this out?

    Ford has figured it out, it’s big end stack tolerance.

    And throw in some eccessive out of spec rod side clearance.

    Big end bearings, crank journals, rods.

    Ford replaced my short block. Did an oil change at 1500 miles post swap. Added Ceratec with the change. It even quietens down normal engine noises.

    So why can't they eliminate the issue? QC on the engine assembly line can't be that difficult to get a handle on.

    Update... Cold start and my engine is as quiet as a mouse this morning. Amazing that 300ml of Ceratec, dispersed into 2.5 gallons of oil can work so well. Car is running, and sounding, great.
    I do not think this is an excessive bearing clearance issue as there is no way you can add an additive to an engine and actually build up material, metal, bringing the clearance back into tolerance.

    Did you ever hear the noise when you rev to 2200 rpms while in park? between 1200-2200 is most noticeable.

    Yes, neutral gear, then gragually play with rpms up and down with small increments and I was alwways able to find the spot. Ceratec did not fix this tick, so that was the reason I drained it.

    used Oil with ceratec looks wery noticeably weird, so do not suggest it if you are under warranty.

    Next I tried 5w30 and that only relocated "the spot" to lower rpms and made it more pronounced.

    So I think this engines preffers 5w20.

    I have not noticed any noise in this range...Just the intermittent BBQ or typewriter noise occasionally at cold startup and after the car has been driven for a while, shut off and re-started later, 30min - 1 hour.

    I would think if you had more bearing clearance, that using 5w30 would be better, as the slightly thicker oil will travel through larger bearing passages easier than otherwise.

    To get 1.5hp out of every cubic inch like Ford does with the 2018 GT, you have to minimize losses everywhere. This third gen engine has a new crank and new bearings, upgraded from ones used in the 2017 GT. You can bet that one of the advantages of these new components was a reduction in big end friction.

    Add some stack tolerance issues to an engine with a (new for 2018) composite sump, and it's no surprise if you hear a few ticks from the bottom end.

    Thr Cera Tech could be cushioning excessive rod side clearance.

    adding something thick to oil increase oil pressure, masking the noise. Ya fixed it !! LOL ..

    I would agree with this if you were adding a significant amount of additive, say several quarts, but one bottle of Ceratec is only 300ml's or roughly 1/3 of a quart.. Adding this to the 2.5 gallons or 10qts is very insignificant. Also it is not super thick like STP oil treatment, maybe thick similar to 75w-90 gear oil.

    Does the "big end stack tolerance" that you think is causing this sound cause issues over the long term or do you think its just a normal characteristic? In other words, is it a real problem?
