Database on engine failures; Voodoo vs Coyote

[526 HRSE]

yea, I do recall something like that…I also find myself engine braking WAY less, and that has been noted as a possible culprit as well

Engine braking is the bees knees.

Why did it shit the bed? What happened to it?

This was back in 2016. It had approximately 3K miles on it. Driving home from work on surface streets one traffic light to the next. I wasn't getting on it just driving normally then the cluster lit up, crunchy grinding sounds come from the engine and the smell of coolant from spitting out of the tail pipes. Tow truck picked it up, took it to the dealer and I never saw it again. Received no explanation as to what happened. Had to lobby hard through my dealer to get a buy back and a reorder a '17 that I had to wait 6 months for.

Love my 2019 GT350. Great experience, sound, handling, revs, etc.
Love the way it looks, so if down the road the voddoo replacement engines were to run out I wouid put in a coyote and still enjoy it. It wouldn't be the same exact experience, but with two very fun engines from Ford you cannot lose.

A similar thing happened to me back in 89 with an 85 Capri RS 5.0 I owned. Was sitting at a traffic light on my way to work when it started to shake and running rough. Coolant out of the exhaust. Turned out the number 8 cylinder exploded and had 5 hairline cracks down the wall. Car had 40k miles and wasnt abused as it had an AOD. Just a bad casting. Shit happens.

There were many more 16 to 18 models produced compared to 19 and 20. So of course the Gen 1 will appear to be worse. There are similar failures on the GEN 2 as well. Percentage wise they're probably pretty close regarding failures.

 

[526 HRSE]

The main difference between the gen1 and gen2 is the rings. The gen1 used a very low tension ring and once the carbon starts building up on them they become less 'springy' and it doesn't allow them to seal to the piston walls properly. After the first signs of blow by, it creates a snowball effect where each time you drive it, more and more blow by occurs because of the carbon. Eventually the rings don't seal at all.

This is why you always hear about how it "used to consume a 1qt every 2k miles, but now it's a quart ever 200 miles". It's because of the snowball effect.

I still believe that most of the destroyed gen1's were operator error. (yet the internet is void of anyone taking responsibility) Someone that used to get their oil changed every 3000 -5000 miles was suddenly surprised their car ran empty of oil due to neglect.

The entire internet created this myth of gen1's being unreliable when it came down to low tension piston rings.

Gen2 engines have different rings and a few other minor changes done to the block.

Edit:

Gen2's will still burn oil but as time went on, people became more educated as to religiously check your oil and by installing separators. With the extra knowledge, it would make sense that there would be less (even at a percentage) blown gen2's but again, this points to user error more than it does to Ford.

I think its a bit of a stretch to blame it on operator error early on. Ford didn't communicate the excess oil consumption issues in '15 -'18 MYs until after the fact. Also, the consumption levels are so variable, some cars get it bad, some don't. A more nuanced take would place some blame on Ford for not informing consumers of steps they could take in order to minimize the issue.

And this is fact based on what? The internet?

Are you not aware of the changes?

True, it may have not been communicated very well, especially to those of us who bought used. I have to say, i was definitely surprised the first time i changed my oil. Still, running your car out of oil and blaming it solely on Ford is mostly what was done.

There's not an internet myth going around that "Ford didn't communicate this very well", it's "Gen 1's are going to blow up".

No. Id love to see where you got this information

Well obviously a Ford engineer didn't call me on the phone and give me a list of specifics, and yes, from the internet.

Which part don't you believe? That the rings were changed, or that the differences are minor?

What the changes specifically were. Besides the block, so that it could be interchangeable with the predator block, nothing has been actually released.

Oh gotcha, yeah, i don't know about something being "official" or not. I would have to search where i found that info. Specifically about the rings.
