2018 GT low rpm engine rattle, cylinder damage pics, Ford buyback process

[choate]

It will be fine man. I understand your paranoia tho. Yeah my car stickered for 47k. I paid 35 plus I think 1800 for the extended warranty. Totally happy with all of it. It did the noise on the test drive too but I just went for it. It’s fine. Yours will be too. Just have some faith man. Good luck

Back in the day the Ford Customer service reps used to reply and be available on forums. They likely all quit lol. My car has a fast ticking/rattling when I am leaving my neighborhood under light throttle from about 2000-3000 till it shifts under light acceleration. I honestly think it’s fine. Car runs great. It’s an 18 GT A10. Seems to not be as loud once it warms up but it still does it. No noises at idle or any other noticeable RPM. Bought used with 12k miles. No oil consumption but don’t run it hard but I have lit it up a few times. She runs strong for sure. I have a 100k extended warranty bc I was worried too

Heck, I remember when the best ported head you could get for the Zetec engines outside of Cosworth was actually a home done Port'n Polish from a retired Ford Escort engineer. His home port was better than even actual performance shops work. Around 2007+ it started to get rare to see actual Ford reps, engineers or techs on Forums outside of Ad guys or "interviews" for marketing.

I think they all will rattle some at those 2500 RPM. Mine does it for sure and honestly the pics of the pistons and walls I’ve seen on here don’t look bad. Idk looks fairly normal to me but I’m no engine builder

Yeah, wasn't exactly super long ago, but maybe 20yrs or so. Something definitely happened though. Maybe Ford telling people internally to stay hands off. Maybe someone tried to sue after breaking something saying that as a post by an Employee they were representing the company. a CYA thing.

I've been watching this thread for awhile..

I have an 18 GT, PP1. My car was bought new last year around this time.
It made the sound in the original video since day one, but it was super quiet originally.

After 5k miles, I noticed it getting louder, specially when the car was cold.

In early December, the car then had 11,500 miles, and the sound was kind of embarrassingly loud, so I decided to take it in.

The dealership I bought the car at, originally said they couldn't hear it. I explained to drive at low RPM's next to a wall with the passenger window down and you couldn't miss it.
They finally heard it and said they needed my stock cat-back in order to touch it, because Ford insisted (whatever). Luckily, I still had it.

After a week, they said they thought the noise was the valvetrain. After inspecting the head, they determined it was in the block. 2 weeks later, they called and said they would be replacing the short block.
The head gasket kit was supposedly back-ordered from Ford and I waited 9 days for them to finally tell me that Ford approved a long block. It was now a month in the dealership and they were still waiting on the block.

I finally got the car back after 44 days.

I was so happy to have it back. But it's been 2 weeks now, and I can hear the same noise coming back at low RPM's. It is exactly the same RPM's as before, between 1,800-2,200.
It's definitely no where near as loud as it was before, but I fear it is only going to get louder.

Something else I notice now, when the car is cold, when I hit around 2,500 RPM's and above, the oil pressure gauge shoots past 80 and looks like it just pegs out. It will continue to do that until I drive it for 10 miles or so, then it returns to fairly normal. I didn't notice that happening before.


Anyway, I am not really sure what to do at this point. I want to put a blower on it, but I am honestly scared to to anything to these motors at this point.

Thoughts?

My 19 PP1 has been doing the same for the oil pressure from day 1. When cold, around 2-3k rpm when 10-20% throttle oil pressure gage goes all the way to 100.
First time having PP so dont know if it is normal or not.

It’s disheartening to hear so many of these stories for which there appears to be no solution anytime in the near future.
Seems lots more f people (including me) are having this clattering noise that just gets worse the longer you let it go, and replacement engines always start doing the same thing right away.
It’s enough for me to want to trade it in and get a Porsche again. Always had great luck and service with those.
The only other option would be to hang on until it is paid off and either have the engine rebuilt properly by a good custom shop, or have a Shelby engine dropped in. And chuck this Coyote boat anchor.

The oil pressure bit is normal. There is an oil bypass solenoid on these cars, the computer controls the oil pressure...that's why you see it jumping around.

As for the rattle...same here. Mine was very quiet initially, and at 8k miles it's louder now. The colder it is outside, the louder it is, and I can make it happen in just about any gear under light load/throttle between 1800 and 2200-2300 RPM. The noise stops as soon as I either give it more or less throttle. Since I've read these things switch between port and direct injection at various load/RPM points, I always kind of figured the rattle was related to that.

I would be interested to see if one of us took the time to attempt to dampen any noise from the HPFP if that would cut back on the volume of the rattle. It seems to me that it's louder inside the car than out too. I can hear it outside, but no where near as loud as it sounds inside the car. Has anyone else noticed this? Think it might have something to do with sound resonating through that sound tube from the intake?

I removed the sound tube (it was one of the first things I did, and I have a catch can and Roush Intake). I can hear the noise the loudest from the passenger side, with the window down. It's very noticable if there's a wall next to me that the sound can bounce off of.

Well, the HPFP is on that side, right on top of the passenger valve cover. So having it be louder over there would follow. I actually bought a 20 dollar go-pro knockoff to mount underhood to try and get a better recording of this sound without the cabin distortion, but I haven't taken the time to set up the test yet.

I had my wife lightly rev the car while I stood outside, before the block was replaced, and I could hear the noise on the passenger side down low (from behind the passenger wheel was the most noticeable).

That's not a great sign, but I also wouldn't take that to heart too much either. I'm not surprised it would be louder down there, even if it was coming from the pump...that sound could easily bounce off the hood and echo down under the car. Or being carried through the exhaust. The real tell would be sticking an automotive stethoscope on the pan/block and see if it's louder there than up on the valve cover or the head.

I know when I listen to mine at idle (I haven't been able to get my wife to hold the throttle just right for me, and she gave up) I could hear the sound clearly around the pump, but my block was nice and quiet. I also wouldn't expect piston slap to be so sensitive to RPM. I've heard cars with pad piston slap before, and they slap at any RPM under the right load conditions. The fact that this seems to be so specific to not just load, but also RPM, suggests to me it's probably not a bad wrist pin...or so I hope.

Not trying to argue or say this could or couldn't be your issue, but the dealership pulled the heads off searching for the issue and then decided the engine needed to be replaced in my case.
The sound it was making before is the exact sound it's starting to make now. :(

Yeah, and you definitely aren't the first one either. Ford did just put out a publication stating that the tick folks have been going in for is "normal". I haven't seen anything on this rattle yet, but I know a fair number of us have the issue. I have two other friends with 18's and both of theirs are quiet. Mine has made the sound since day 1 though.

It's just strange to me that you'd have two bad engines in a row, the odds for that don't seem great. I had an 18 F-150 5.0 as a rental car over the summer, and it rattled too...just like the mustang. And Ford sells gobs of F150's, so you'd think if there was some systematic issue with the Gen3 5.0's the F150 guys would be seeing it in droves.

I almost wonder if the tech trying to find your issue happened to actually locate a separate problem in the process. I'm super tempted to pop the plugs out of mine and look down the cylinders with a bore scope to see if the cylinder walls on my engine are marked up like some others in this thread. Still..it does seem odd that piston slap would manifest itself that way.

Did they say what they found wrong with your original engine?
