My 2020 GT 350 Engine Blew today

[morjo02]

seems like most of the GT350 engine problems are with the 2019 and 2020 years...

OK folks...having read every reply. Does anyone have a legit list of engine failures for each year. (Model years 16-20) or is this a best guess deal?

Not looking for any b1tch1ng whiny internet troll$hit. Looking for facts/percentages of failures.

In a nut shell, no. This has been discussed ad nauseam, but you knew that before posting. Attempts have been made to catalog failures, but it appears user error ( like never checking the dipstick) along with a treasure trove of other circumstances, I.e. weak parts has lead to the engines over all years of production failing. Even without specific corroborated instances it still appears that the percentage of failed engines is very low.

I work for the UAW and I’m a split ticket for them. Unions make me go yay and nay at the same time. But I’m gotta tell ya here that the vast majority of these engine failure are probably not the result of bad workmanship. The main reason is simple, anyone who get a job hand building engines is someone that is extremely proactive within the company and doesn’t mess about or they’re good at there job and don’t have major quality issues. It’s not a job that billy Bob gets you have to be chosen. I still think the vast majority of issues are the direct result of it being an FPC engine and having full on freak engine failures. Excluding the recent valve spring engine failures, we have yet to see any real world data on engine failures other than pure speculation

The fact that many people dont know about money shifting is another concern and again proves my point of people with a knowledge of far below average required to own a car like this are around. Not trying to be condescending but this is not a car for average person to own.

money shifts happen all the time and people don’t fully understand the situation or even realize they did it. This is also why cars like the cobalt SS, wrx, sti, focus st, RS. Have gotten such a bad rap over the last few years for going bang all the time. The vast majority of the time it’s the 18-25 year old owner acting like it’s forza horizon and on the highway in 6th gear going full boost at 2500 causing LSPI. Then going on the forums and making a scene out of it. Same thing with the money shift nobody is going to come out and go. Yeah bro i was in 6th and accidentally put it in 2nd gear, now it’s knocking is it okay lmfao

i love going on other forums and just reading up on other plateform. And almost every focus st engine failure I’ve seen was “i was on the highway and it suddenly lost power bro”

Money shifting is flagged nowadays though. Probably for the last 10 or 15 years now. ECU will record any RPM over the allowed maximum and save it for review later so they can void your warranty.

nothing new for the euro guys but I’ve never heard of Ford directly voiding a warranty because of it. Most of the time a company uses that as a way to avoid paying for warranty work. Now with Ford going above and beyond to cut costs that may very well change

What’s even more interesting is back when the boss 302 was in development, a Ford racing engineer was bragging about how a prototype boss 302 engine. Survived a 9500rpm downshift when at a test track by a bad down shift. I can find the link it’s a good read

from the boss development copy and paste

We should specify that for a valvetrain specialist such as John, Boss engine speeds do not end at the production car's 7,500 rpm. "We have a design guide so that if the fuel shut off is 7,500, we want the valvetrain to be stable to 400-rpm over that in case of over-speed events, missed shift on a downshift, or whatever. [This is to] make sure that if there is a momentary over-speed, the valvetrain doesn't come apart. If you throw a rocker arm or bend a valve--and it doesn't take long to do that under the wrong conditions--then you can lose your whole engine." Told that one of the Grand Am racers had managed to wing a RoadRunner to 9,500 rpm on a missed downshift with no apparent damage, Mark's commented, "I can only warranty it to 7,900, but I'm glad it worked!"

To be fair, just because the engine survives the initial event doesn't mean it won't come apart later. I've heard many stories where people think they got lucky, then the engine throws a rod 1500 miles later. The extra force exerted on all those parts is really hard on the bearings, wrist pin, etc

Found it :

Cole Trickle : Tim, I realize Harry's been around a long time. ...

Harry Hogge : Well if he wouldn't get excited and over-rev the son-of-a-bitch the engine wouldn't blow. Now, Cole, when you shift the gear and that little needle on the tach goes into the red and reads 9000 RPMs, that's BAD.

Is this movie the reason everyone thinks a singel over rev is going to destroy your motor?

There are also a few Forum nuts that were so bitter, that they would come back with a new account talking about how their engine blew up. I've seen a prior member here on another forum (where he was less likely to see protest) sorely exaggerating his experience as well. So the negative experiences always bubble up and usually with spite.

This feeds my latest theory - don't kill me ;) Note that everyone has a car preference and it's usually what they own. Also when people have theories about what caused a failure, they tend to propose the option that does not affect "their" car ;)

Very true - these days more than ever, people don't like to take responsibility for their actions....and I can see this especially with a $20k engine. A previously overly-moral person who money shifts their car resulting in an engine failure is likely going to drop the car at the dealer and "let them figure it out" as opposed to being forthcoming about their episode ;)
Same for checking oil - these are not Toyotas (I've said this before! ) they are not zero maintenance cars!

I wouldn’t either, what do you mean i over revved the engine. I know nothing lmfao
