10% of 3500 is 350, not 35.

10% of them show up here which is only 35.

Aluminum engine blocks without sleeves have been a disaster just about everywhere...ask GM who tried it on the Vega and BMW who had the imfamous nicasil lining in their V8's in the early 1990's.

yeah, I had one of those Cosworth Vegas, what a pile of garbage.

There's way more than 35 who've voted in the poll already. Thing is, not every 2018 with this rattle or engine issue was sold to a M6G member who happened to vote in the poll. The poll is a small cross section of 2018 owners, but I believe it has some validity.

How are these engines faring in the F-150? Does the F-150 get the DI/linerless version of the Coyote?

I have been to some of the truck forums. The F-150's with 5.0 engines are not immune and report the tick issue too.

I am not pretending to have the exact numbers as I stated in my post. The process of thought was What I was trying to illustrate. I am unsure of g2g sales percentages and how many of those sales make it to this forum. But you can see, the numbers in the pole are significant because each stage of selection is another fraction of reduction.

I have the bbq tick and the rattle, at the time of the poll it i posted yes did not take it to the dealer yet. I have, they documented it. said the tick is the normal coyote tick thats been around since gen 1 coyotes, the rattle is not "norma'" but didnt look into it further waiting for ford to figure out the cause and issue. It documented, i came home put on my MGW, headers, xpipe and tune.. like others have said, they took out 8lbs of cylinder liners, it may be "common" to hear the rattle, many f150's have it. others around here do also. I have a 60k warranty so im not worried ill drive it till it goes because worrying about it isnt going to fix it nor let me enjoy it. If it goes it goes, ill have a new car in 3-4 years and this will still only have 20-30k miles since its not a DD.

My sentiments exactly.

This is my issue with the whole "cell phone/gotta have the latest greatest" consumerism mindset that has invaded every facet of american life. Watch the movie "Jurassic World" .....there is a subtle statement made in that movie when discussing the "Indominus Rex" which holds true for a lot of our society....It's become a two way feeding frenzy...The manufacturers pump out new and exciting changes when changes are not always for the better just to get consumers to purchase new when they have a completely fine product to begin with. I've stopped watching most of the Mustang Enthusiast You Tube Channels because these guys are turning over their S550's every year ... one guy is on his 3rd or 4th in less than 2 years. What happens to all of the 2015-17 that are sitting in lots?....Everyone was so hyped by the 2018 refresh while I was disappointed in the cosmetic changes which for me were not necessary and was very skeptical with the tinkering of an already stable, proven coyote engine.
I like what Ford has done with the GT350.. they left the product alone and fixed the issues that came up from the 2015/16 run. They should have done the same with the S550.

I've seen this guys videos. He has the same idle tick that everyone has but he's convinced it's a major issue. Why do you think the second engine did it as well? All 2018+ 5.0s have the unsteady idle tick. His 3rd engine will do it too.

Nothing to see here imo.

Agree. All of our 100k mile plus 2014 F350's make the SAME EXACT noise and have had ZERO failures and we REALLY out em to the test. Here's how they sound. It's not exclusive to the Coyote.

I'm not saying the type of coating is the issue but rather the different rates of expansion between a cast aluminum block with no cast iron liner and a low expansion Hyper piston. they absolutely expand at different rates and amounts and clearances do change.

man you guys sure do like to argue. maybe the poll suggests that it's normal. multiple people have it. if you said my big toe hurts after I drink a bud light, then sure enough the next guy will go you know what mine does too! bud light causes big toe issues! let's start a poll

 

[sigintel]

Dunno if this helps avoid excess piston float on the rings (sloppy slap piston rocking in bore).
My breakin:
Keep engine between 3-5 rpm during first 200 miles up to 2/3 throttle.
3-6 rpm occasional full throttle 200-400
4-7 rpm occasional full throttle 400-500
3-7.5 rpm 500+ Increasing to 4+ sec WOT
600+ miles: repeated 4+ sec WOT on track to CHT 225.
Prolly do compression test soon.
Then maybe wait till 800 to go sustained track use till CHT 245. Figure if ring gap too low, itll blow a ring land at that point.
Then compression test after track weekends from there on.

Update:
Lol... Have cold tap thats prolly piston rocking or piston slap at 504 miles.
Goes away once warmed up.
No plans to let up on it, gonna let it eat...

 

[choate]

you guys are good at diagnosis from reading a car forum and reporting how you heard an engine sound. no need for a mechanic. it's definitely piston slap or a lash adjuster based off what i read on mustang6g

 

[growler]

More bad news from this junky engine, look how everyone is worried about the rattle and tick as they are running 8's on a stock longblock,..This noise is just terrible it ruined these guys day!
