Just started the dreaded tick.

[silverflash]

The ticking, knocking and especially the 2-3K rattle got to me- and after the dealer had the car 2 weeks, the tech said the rattle was "noticeable" but the SM end up having the final say and his conclusion it was "normal" mainly due to the bulletin Ford issued stating the type writer tick was "normal".

The type writer tick did not bother me- it very could be the DI. But mine started making a knocking sound and the rattle was getting worse- which really concerned me. And having owned so many different cars throughout my life time, none of them made a rattling noise (piston slap) like that. So despite loving the car and also needing to downsize my fleet of cars, I traded it in, along with my Fiesta ST to a local dealer for an economy car to get me by. Someone bought the GT right away, within a few days so it was not on the lot long. They may never hear the sounds and all may be fine, who knows.

i have the exact same thing going on in my 2019 pp1 with auto. dealer/lead tech finally said these are noisy engines and if it gets worse bring it in.

i am not pushing it because a new engine would probably due the same thing.

if ford did a buyback, i would probably do that and go back to buying japanese. my 2007 xterra 4x4 4.0 with 145k miles doesn't tick/rattle or anything....yet my 2019 gt with 2000 miles does.

with that said, i do enjoy the car and if i drive it as designed, it seems to not tick.

per the tech/dealer, you can't baby these engines. run them! his words not mine.

The reason guys get upset about ticks that come and go with oils and additives is because worn out engines seemed to respond well to thicker oil and additives.


So we once again go back to the issue of having to loosen things up tolerance wise in order for the motor not to grenade at cold temperatures and high rpm. As I recall this was the idea floated at a engine machine shop and I’ve seen nothing since then to dispute it. This problem may be a hard one to redesign financially for Ford but what do I know.

What I do know is that I’m not buying a 2018 and up GT until they give us a tight engine that does not behave like it’s ten years old. I’d rather they give me the tight engine and have engine management cut horsepower and revs until fully warmed up.


But that’s just me...

The nonly reason for asking is, I cant understand how a motor goes from making no noise, gets an oil change and then starts making noise. Only 2 things have changed; the oil and the filter. There has been more than 1 that has said this same thing. I don't get it but do agree with rebellovw, just drive it. That's what warranty is for. Good luck to you.

Well mine definitely did not make a ticking or rattling noise when new. I test drove it 2X before I bought it. And for the first 2K miles all was fine. Then the ticking started, then the rattle. I changed the oil at 4.5K, it had no effect on the ticking or the rattle. The rattle seemed to get worse with more miles up to the 5.5 K when I finally brought it in to be checked out.

Agree. Until there are actual cases of engine failue due to the tick (under warranty) we are stuck with it and there will be no voluntary recall/fix whatsoever.
Thankfully my 17' GT does not have it. Oil change is about due and I am at 27K miles... doh.. wish me luck.. lol

Right on. I changed oil in my '17 last year with 4000 miles on it and still is quiet. motorcraft filter and mobil 1.

Though on and off, it is a singular tick that is in fact synchronized with engine RPM.

The BBQ tick is random, not synchronized with RPM. The BBQ tick is also affected by the friction level of the oil, that's why Ceratec makes it disappear almost instantly. And also why the tick can appear right after an oil change. Ford says the BBQ tick (typewriter tick) is harmless to the longevity of the engine. Ford also replaced short blocks to fix ticking engines before they came out with the SSM that said the ticking is "normal". Obviously Ford knows the cause of the ticking is in the bittom end. Guys with ticking engines verified to have excessive rod side clearances.

I don't recall one report of someone with the BBQ tick having parts in the bottom end being measured (rod side clearance, crank end play) and all found to be within factory specifications.

Has anyone got a link to a report of a ticking engine having all bottom end clearances within factory specifications? If so, please post the links.

For every person who found the same issue, theres been a dozen or more who didnt. If it was as easy as tighten manufacturing tolerances this would have been solved years ago. So yes, mostly debunked theory.

Manufacturing scatter of parts dimensions. A design can be perfect on paper, but if manufacturing can't meet the drawing specs then you can get parts assemblies with out of spec (large or small) clearances.

It would be interesting to know if part of the bottom end assembly process is to measure the rod side clearances and crankshaft end play, or do the parts just get assembled assuming they will all be within clearance specs? My theory is the latter, otherwise some engines with hardly any miles on them wouldn't have rod side clearances outside the max allowed specification - why are those engines leaving the factory? Seems that the QA is not there to catch out of spec assemblies on the assembly line.

It definitely follows engine rpm. I hear it all the time in videos, and my own. Even when people rev up the engine the pace also increases evenly in frequency as rpm increases. It's just the sound itself is intermittent. Listen to some videos where people slowly rev the engine and still hear the tick, you'll know what I mean. It's a singular item that is making noise.

That said, I don't want to keep arguing about it, because neither you nor Lion, nor anyone else on here, including Ford themselves seem to know or want to tell us exactly what the exact cause is.

My 19 has a consistent tick from the DI. Sounds just like every other DI car I've owned. At around 6k miles it started getting the 2k rattle. Worse when cold and almost unnoticeable after the car is fully warmed up but very consistent between 1800rpm and 2800rpm. I've also noticed the rattle sticks around more when my wife is in the car and I'm driving conservatively. When she isnt in the car and I'm smashing on it, it almost goes away. Plus the car seems to run smoother on days I beat on it.

You mean like a rod that goes around the crank in perfect sync with engine RPM, but is somewhat random in nature because the rod doesn't slap the side of the crank journal exactly the same every revolution? That's what I mean by it's random.

Until someone can show definitive evidence that it's not excessive rod side clearance then I'll keep that theory because from everything I've seen so far, more evidence points to that then any other cause.

FYI for those here not up on all the Coyote noises, the BBQ tick (typewriter tick) is not the same noise as the 2000 RPM rattle, and are caused by two different things.

I'm not going to say your "wrong", because you may very well be spot on. I'm just tired of all the theories with no one with real compiled evidence to give a 100% answer on the issue. Basically, about the only way I'll truly accept any explanation at this point, is if Ford finally gets the coconuts to admit what it is. If it is what you theorize, then it probably isn't a serious mechanical problem, just audibly annoying. The fact that Ford won't admit that, means they are just rotten for not fessing up to the real reason.

I did find a thread on the Ford Forums, where a guy tried about 5 different oil viscosities, and said that 0w40 full synthetic actually seemed to make the noise the quietest. Interesting how the thinnest oil at lower temps actually seemed to work the best. Then, another member stated that Ford said to add some kind of "oil thinner" to help alleviate the sound (I believe Ceratec lowers viscosity, if I'm correct). In their case, it seems like heavier viscosities, though more protective, seemed to make more noise. .....Interesting.

For 8 years? My six sigma training has issues with a manufacturing variance explanation.

Yes, Ford is rotten for not saying exactly what it is, and IMO is hiding the fact that some new engines are out if factory clearance specs. Instead, they know the engine isn't going to blow-up from the typewriter tick, so after 8 years the finally said in a SSM to the dealers that it's "normal". If they admitted it was actually caused by part clearances out of spec it would cause a complete meltdown for them. I don't expect anyone to believe my theory, I'm just giving my viewpoint based on everything I've seen over the last 4 years on the ticking issue and trying to put pieces of the puzzle together.

0W-40 is still many times thicker when cold than any 20, 30 or 40 weight oil is when hot. If he was talking about the tick going away when the oil was hot, then 0W-40 is still thicker that 5W-20 or 5W-30.

Ceratec additive is pretty thick, so it most likely would increase the viscosity a hair even though its only 1/3 qt to 5 qts mix ratio. But IMO it's the big reduction in the oil friction factor that makes the ticking go away. Some guys have ran Ceratec for a full oil change interval, changed oil without adding anything else, and the ticking was still gone because the Ceratec left behind an anti-friction coating as advertised. Another clue that the cause of the tick is affected by the friction level between moving parts.

It's Ford, look at some other long term issues that haven't been fixed over the year's. I'm with you, if it's manufacturing issues go track it down and fix it. Pretty confident it's not a design problem, otherwise way more would have the ticking issue.

I wonder if this is why a lot of guys are saying to run 5w50 full syn then?

I thought 0w when cold is supposed to have viscosity like water? And 5w is slightly thicker when cold?

As far as Ceratec goes. I plan to start running QSUD 5w30 next oil change. We'll see how long the existing Ceratec remnants hang on after the oil change.

Or the tick is oil cavitation and different oils/ additives cavitate in different ways.
