The true reason unveild behind Gen3 coyote tick. According to MPR racing engines

[Spart]

I will say one solution is to tighten everything up but enforce engine performance limits on the car till it’s fully warmed up. But that is like waving a red flag to a design problem inherent to the engine! But that could work. What a fuck up! And yes saying “fuck” is appropriate when the conditions warrant it!

Allowing water and oil temps to get into operating ranges is so much more critical on a motor capable of 7500 rpms. Jumping in cold car and going into the higher rpms to soon can be very detrimental to engine longevity. I bet quite a few people miss this pretty important (especially DOHC) step of owning a performance oriented engine.

I think this would be a good thing to have regardless of engine issues.

My buddy's LC 500 has a DOHC 5.0L V8 with 470hp (sound familiar) and the car will slowly give you more and more redline as the engine warms. You can actually see the redline increase since the car has a digital cluster. Surely this wouldn't be difficult to implement with Ford's tech.

On my GT350, I'm always looking over at the oil temp gauge waiting for it to creep past 190. On cool days (car has an external oil cooler) it doesn't ever get there.

If this is indeed the cause I would imagine Ford decision makers may have at least for a while decided to absorb the more than a few actual bad engines. The sad thing is they would also have to implement the ''That's a normal noise'' answer to all the complaints that the service desk. I consider this a problem based on mass production cost cutting measures.

The outfit that previously handled the spray in liners for the GT500 and GT350 probably couldn't take on the large volume of work for a mass production engine so it was done on the cheap. Just speculation on my part.

GT350's have piston slap issues also. Not sure whether the GT500 engines were known for it, the only example I've ever driven didn't seem to exhibit any piston slap.

My GT350 has piston slap during low-load situations when the engine is cold.

Yeah, I've heard of a few on the GT350

Has anyone considered the possibility that MPR Racing has adopted this theory for the argumentative convenience of pushing their custom built engine sales?

I fully admit that I've been pushing this piston slap idea, which I think it probably is. However, we all have to be willing admit it may very well be the exact same oil film cavitation issue found in the PowerStroke and Duramax engines. They have the exact same random typewriter ticking sound as the 5.0L, and Ford even has a TSB out there for it. If that's the case, then there's basically nothing wrong with our engines, and the few that have been replaced for scored cylinders or bad bearings are just anomalies which do occur more often in these cars due to the way we drive the heck out of them. A mustang at 5,000 miles that goes to the drag strip every weekend can easily look the same or worse in its cylinders than the same car driven 100,000 miles that was driven normally as a daily but never went over 4,000rpm.

Mine still sounds like a meth-addict playing a xylophone when cold or semi-cold, but goes away when at operating temp. Has 2100KM on it and is probably a little quieter than it was when brand new. Goes hard, no rattle at 2000RPM, but has a rhythmic metallic noise (valvetrain-sounding) all the time.

I think I posted this once before, when my 18 was at ford with the tick, the hotline specifically stated it was more than likely a clearance issue with the lower end of the engine.. Crank / bearings etc.. Another local mechanic I know that has been working on Mustang's for 25+ years and helped develop some AR headers agreed with that.

Ford techs were to lazy to follow the hotlines advice and never investigated further.

We will never truly know the cause.. I can say my first 500 miles on 2019 with no tick, knock sensors never showed anything positive.. Now that my 2019 has 2k miles developed a tick here and there, sure enough knock up to 1 degree now, not worrying, but if overtime it continually goes up, I'll say the tick, whatever it may be, is causing damage.

I wondered why you asked since he had quoted the person. Is this new forum software so good it even blanks out quotes of people on your ignore list? I like it.

 

[michail71]

I wouldn't say "true reason" he's just posing an educated guess like most, his guess is just MORE educated than most.

The guys at Palm Beach Dyno and RareFab (around the corner) are automotive geniuses. I'm happy they are locals!

Dude I just about had enough of you, what mods are done to your car ?

What have you ever done ? I bet I have forgotten more than you will ever know.

Having a Pine Tree air freshener in your car isn't considered a mod.

Why don't you do the world a favour and STFU.

So now mods equate to asking for proof of where your BS comes from besides some random guess or assumptions?

LOL run along cupcake

 

[NIXPP2]

Like I said in a post earlier today, dropped mine off this morning. The tech and service manager made no attempt to say that it was normal. The couple of folks in this thread that think there isn't an issue simply because they aren't experiencing it are absolute morons. Their posts are barely readable and people that come into discussions just to troll fellow enthusiasts should be banned. Seriously.

ive never said it doesnt exist. i just want proof of whats causing it not some bs guess or assumption.

Must be

If Ford thought it was "normal" I'm sure by now they would have said as such and stopped replacing the motors.

For sure, given all the social media talk about the engine noises and engine replacements. If it really was normal, Ford would want to quence the fire ASAP.

This is what mine sounded like and the car was replaced by ford. Scoring on cylinder 6 and it was losing oil as well. Hopefully they take care of you

Dear God!!! That's definitely NOT the BBQ tick. That bloody engine is shot.
