Stock Coyote Cracked Crank Snout

[Cobra Jet]

Hey all, I have a 2018 GT with 39k miles of which I have put on only 9k. Bought the car in January of 2022 and it's a summer only/road trip fun car for me, and also my first mustang.

I installed a magnetic drain plug 5k miles ago. When I was performing the second oil change under my ownership when I discovered a tooth from the crank sprocket on the drain plug. I had no idea anything was wrong. The car ran flawlessly and had no extra noises. I took a chance and brought it to the Ford dealer that I bought it from with hopes that they would help me out in some way.

I figured the crank sprocket fatigued and lost a tooth but the crank is cracked and the dealership wants to install a new engine for $13k+. I am heart broken because I have barely owned the car, Ford corporate wont help me out in any way because it's 3 months out of the powertrain warranty and it's unlikely the dealership with help cover any of it as well. Feels like I was sold a ticking time bomb.

I guess I am looking for any information as to why a stock engine would crack the crank snout, or if I have any recourse at all for the huge expense. All I read about are supercharged or heavily modified cars that experience this. Am I unlucky or do we think the car has some stories... No real evidence of it being super modified or anything.

Thanks!

You’re not the first with this issue on a totally stock Coyote, and unfortunately probably won’t be the last either…

There’s obviously a manufacturing defect or inferior parts being supplied by the contracted Vendor to Ford.

Very low chance the crank is cracked. Worst case scenario you'd put a shortblock in it, not an entirely new engine. Dealer is either taking you for a ride, or just wants to do it the lazy/easy way or not at all.

If it is Londonderry Ford they ARE taking him for a ride.

Infuriating. Makes me wonder how long it was broken.

Fortunately it's not.

It can keep working with a tooth broken off for quite some time.

Still, a bad crank sprocket is a far cry from a bad crank. One is just a little bit of time and a pretty cheap parts list.

100%

A short block from Tasca is $2745 which is A LONG way away from $13k. Hell, a long block is only $4137.

Im really sorry this happened to you, but if the crank is in fact bad, it might be time to REALLY get to know your new Mustang.

A motor swap is not as hard as you might imagine.

The beauty of these cars is they're cheap to fix given how much power they can produce.

Yeah agreed.

My biggest regret is bringing it to the dealer in the first place thinking they would help me out in any way. After their diagnosis I'd have to take the car back disassembled with parts in the trunk and be on the hook for the $1,500-2000 for ~10hrs of labor. When I was adding it up (including that diag cost) considering doing the swap myself, I was seeing long blocks for $7500 from Jegs and Summit. It would save me $2000-3000 but I am neck deep in other car projects that are taking up my working bays. "They will be done over the winter"

It is still up in the air at the moment. The dealer sent a request for financial assistance to Ford after I was denied. If that doesn't work, it sounds like the dealer MIGHT work with me on price. We'll see....

The long block from Tasca is $6,869.33 with shipping and core charge.

Welp, good luck!

 

[furdfan2018]

Also worth noting..

You wouldn't pay the $800 core to Tasca -- obviously they'd take your old parts.

Shipping you can usually get a deal on with a discount code available on this site or SVTP, or another mustang sight.

If it's still too much, buy the shortbock which is much cheaper.

Hopefully the dealership can cut you a deal, but then youre at the mercy of incompetent hacks once again.

Could keep the old engine, fix it and sell it to make a couple bucks back if I went that route? I hate the idea of the dealer doing the work, but having a 3 year warranty for parts and labor is a slight plus.

My car ADD is really kicking in too...

Yeah agreed.

The sad part is, IIRC, they could have borescoped it in 20 minutes and saved all that labor. I had taken a bunch of pictures of everything with a borescope several years ago. I'm pretty sure I was able to go all the way to the oil pan through the oil cap.

I told this to the service advisor I was initially working with and then he disappeared for 2 weeks... I then called them and the service manager had not considered this and had already given the go ahead to tear it down. Just getting screwed from every direction.

 

[furdfan2018]

If the Service mgr gave the "tear down" go ahead -- without your consent -- he can eat the labor charges for that crap.

What a bunch of idiots.

 

[SMOKE46]

Prolly had a pro charger on it before then was taken off

 

[SMOKE46]

Maybe you can use mags on laws to recoup

 

[SHOdaddy68]

Isn't the powertrain warranty 6 years 60k?

I Effin hate the "stealerships". Haven't had a single positive experience at any Ford service dept.

Not many dealers rebuild any major component anymore. They're all parts replacers now.
