Mine was a dropped valve at 900ish miles. Looking like a bad valve retainer, or assembly.

900? not 9,000? If so, I'd assume that's a fluke. Bad part, bad assembly, etc. Experts, do you agree or disagree?
I'm more curious about cars that are fine for 5k, 10, 15k and burn ZERO oil, then one day they burn a qt in a short time with no other changes. (if we believe the owners that nothing else changed, like racing or excessive redlines on cold starts, etc)

Yes, 900 miles. Well documented here in my engine replacement thread. I’m not the only one with early delivery mile failures- at least three others. We all seemed to have a valve dropped, in one the retaining clip was found in the oil pan.

I wonder, is that the sort of thing that is ether bad or not bad? And if bad, it shows iteself very early? And if good, it never shows? Or could it develop over time? I heard there's a valve issue with the Z06, I think C6, and if you run it hard, the problem surfaces. So you can essentially do a valve job preventatively and it's fixed. $2,500. Done. That's the sort of thing that will eventually, hopefully, be good to know. Same as IMS bearing in 911/996. replace it with aftermarket every 6/60 and you're fine.

Update: Picked up GT350 with 3rd engine replacement after dealer had it 2.5 months (unacceptable - blamed COVID, but got a nice loaner). New engine had a little rough idle when picked up but settled down after some driving. Dealer damaged vinyl stripe, misaligned the hood severely and cracked the front facia just above the splitter..I let them know. Took another month 2 get parts and took in for a scheduled appointment which took 2 weeks(Got loaner). Hood still not correct, they replaced the air splitter instead of facia, front nose popping out from fender now and they had a vinyl guy try to match the stripe (I was livid, and went off and had them order a OEM decal). Facia has been ordered..still waiting weeks later. All this coupled with 2 AC hoses blowing off and several issues with parking brake I lost confidence in this car and this dealers service dept. With 19,700 on odometer, 1,800 on new engine I went to another dealer last night and and traded for a loaded Explorer. I loved this car when it ran, but this is too much. I'll get something else down the road. Hope you all have better luck than I have.
On a side note after I got 3rd motor broke in I was on a road trip and ran into a guy at a gas station from Romeo engine plant that was a chief quality control guy and he asked how I liked the car...well I explained my issues and he verbally admitted that 15-17 had major issues with high oil consumption and 2nd motor that snapped a vale he said said yep, Ford had a bad batch of valves.

Was you dealer a small town dealer? It sure doesn't sound like they have a plan to service/repair higher end cars like the Shelby.

I think it was discussed. The oil usage is related to blow-by. The gap between cylinder wall and cylinder head is larger in gen1 than in gen2 voodoo engines. Anyone may correct me if I'm wrong.

So where is the proactive notification at a minimum and better yet recall of all affected engines? Oh wait, this isn't Japan or Germany - this is "if it didn't blow up in your face, be happy" America.

Interesting feedback. Wonder if there was a "bad batch" in the 15-17's that can be blamed for the consumption issues. Since there are several in that window (mine included) that are fine. Seems like there were problems throughout the entire line since there are a decent amount of 18 failures we've seen as well.

how many GT350 owners are on this forum ?
According to
The poll 73 engines have failed but I wonder how many owners are represented here- I bet the math comes out to a 1.5% fail rate

I'm near a dealer that I almost talked about buying a 350 from. Now for the last few months after I finally saw it was sold. They have the car sitting there inside the repair center for nearly a month. I'm willing to bet that's the same GT350 from the floor and I bet you that it's waiting on a small bloc. lololololol WTF Ford. I didn't buy that care for that exact reason.
