2.0 engine blew up. Now what

[ABTremor]

I thought you stated in another thread you had a custom tune done and a modified air intake???

So which is it? An ALL stock engine and tune or a modified intake, several Forescan changes and a custom tune??

BTW the "custom" tune you previously stated you installed probably contributed to the detonation issue you experienced. Very, very seldom ( as in, I've never seen it happen in my career as an equipment/engine analyst) does a spark plug burn off the electrode and cause cylinder damage without there being a fueling and timing issue involved.. just sayin' is all

So, I just read the whole thread, and am still confused. Is the motor toast or is it running? If compression is good across all cylinders, you don't have anything stuck in a valve, because you wouldn't have good compression on that cylinder.

The dealership should not void warranty for an intercooler. It doesn't change the tune, nor does it hurt the engine in any way, it only allows the engine to run as intended for longer. They didn't even look twice at my intercooler, or downpipe for that matter when my trans failed.

I would take it to the dealership, and explain what happened to the spark plug, and have them look into it. Especially if you are under 60k miles!

I talked to my local one who replaced my axles. I was turned away by one dealer and the one who actually replaced my axles almost turned me away, the tech said he didn't notice anything. Then I got the Jim ** manger shop advisor to go for a ride while I drive and he felt it instantly. So he fixed me up.
I called that same dealer last week and told them I got a misfire, cylinder 2 spark plug was broken inside the engine when it was running, ground strap broke off while running. Found it when removed the plug. The first thing he said was, are you sure you didn't break it when you took it out. Already placing blame on me. Now this is not the same guy who did allow my axles to get replaced. But his brother who is **Eric, manager shop advisor. They are sons of the dealerships owner.

I have a friend at a local shop who works on alot alot of ford ECoboost vehicles who aren't under warranty so they do rebuilds and replacement engines. He said cylinder 2 and 3 are the main ones to have EGR caused misfires, due to purge valves, and those are the cylinders affected with the coolant issues on older models.

I never had a vehicle with warranty, but I know the axles was a 2 different dealer fix with having to show them my axles was bad. Now the engine clearly is bad chipped piston and possibly valve, on the borescope looked like metal around the cylinder wall but was hard to tell with the borescope camera, (hard to bend it at the angle I needed )

so I called another dealer 30 minutes away, said I had a misfire code and somethings wrong and IDK what it is. if I play stupid like I know nothing about vehicles. They seemed to want to help me a lot more. And I really think that's a shame. I take good maintenance of my vehicles. Oil changed every 5k. Air filter checks. Tires rotated I don't beat on it. It's my daily 100 miles a day.
But If I tell the dealer spark plug was damaged while running not sure how and a piston has a chipped spot on the valve relief, they act like I messed it up.

Hoping a dealer will fix it. But if I have to pay for the repair.....for $1800 I found a 2.0 maverick ecoboom. With 20k miles. But for $2200 I could get a Corsair 2.3 engine.

I'm just on the fence bc ford warranty said a spark plug isn't covered under warranty due to being a wear and tear item. But I don't want them to pay for a new plug. Hell I'll buy the plugs. But clearly the plug damaged stuff. Now what exactly caused it who knows.
Kinda was wondering if a injector wasn't flowing enough for that cylinder or the purge valve caused issues. Either way something caused it to go lean or get too hot. I did start to get a misfire code on other cylinders checked those plugs and they looked ok. Put them back in and no code. Came back for them.....

That's a lot to read sorry for rambling.

Stock intake all stock motor ,87 tune and 91-93 in the tank. That's all I use is premium gas

Forscan changes to add cruise control , speed display and lane keeping would not contribute to an engine issue.

" 87 tune"

So.... you have a custom tune in it.

Bye bye.

Not a custom tune. Has the OEM factory calibration update from June the dealer put on when I had axles replaced. That is for 87. As my ford manual states.

unless he edited ..which maybe he did. he did post previously about a tune, so I'm guessing he's hoping to get warranty coverage.

 

[awscheetz]

No I didn't edit anything. When I had my axles I had to remove the tune as recommended by all tuners before it went to ford . When they fixed my axles they did recalls and there was a brake module, air bag and ecm updates. When I got it back it wouldn't work with my tune device anymore due to being updated, different calibration not matching my tune.. So I have not had any tune other than stock ever since I had it in the shop in. So once again I will say I don't and have not had any tune or calibration other than the stock tune on my truck ever since Ford has had my vehicle.

 

[surfstar]

Ok, so it was tuned. But not when engine go boom.

Try and get it warrantied, but anyone who tunes their vehicle should know of the risks they are taking. There's always a chance the dealer won't care / look closely if they want the warranty work...

I’m so confused

Don't poke the bear.
Today's little motors run at the ragged edge as it is. I remember when a half horsepower, or less, per cubic inch was normal. One HP PCI was a hot motor. Now, two HP PCI doesn't even garner attention.
You can go fast, or you can go far.

Looking at the 2022 Owners Manual, the spark plug maintenance mileage is 100K, unless towing or constantly hauling weight, 60K under those circumstances. With a broken-off electrode, you would think it would be under warranty, unless the 60K powertrain limit has been passed. UNLESS they can determine that the ECU has been modified, if the previously-installed tune left any trail.

Exactly, my dad had a 271 hp 289 in his 65 Ranchero. That was always an impressive number to me.
Technology has created a lot of jaded car people. An Ecoboost Maverick would have put a whoopin on that beautiful Ranchero.

When FORD did his updated ecm program any sign of a tune was wiped out. The counter gets reset to zero.

My recommendation is if they dont fix it, get a 2.3.

 

[ABTremor]

Honestly I feel for the OP, he's looking at a very expensive repair.

BUT, that being said......

He's mentioned using an SCT BDX tuner to load his tunes. That device "marries" itself to your ECM when it's first connected, meaning it performs a type of handshake with the vehicle ECM and after that initial connection it will only work on that vehicle, preventing the tuning of multiple vehicles with the purchase of one device.
It's quite possible the device has left/set a "tattle tale" bit in the ECM that Ford can see -- if they look for it -- and they might since this type of failure is quite rare.

FWIW, most aftermarket tuning devices will leave similar evidence of thier use.

One lesson everyone can gleam from this is educate yourself about the possible effects of any changes you want to make to the vehicles operating parameters before doing so.

It's imperative that you know what your doing if you have any intention of modifying the AFR or ignition timing because some very bad things can happen when changes are done incorrectly. Making changes affecting cylinder peak firing pressures and when they occur is not for the faint of heart. Any change you make to one operating parameter will have a cascading affect on several others.

For example, Mess with AFR, it affects Peak cylinder pressure timing (when your combustion occurs), cylinder heat genetated - which may necessitate a different spark plug heat range, changing the ignition timing is also then required..... It ain't as simple as most people think.

Also some research on what a lean missfire is, what detonation is, thier causes, and the difference between the two is a good idea.

And like they say... you want to play, you gotta pay.

I find it odd that every 2.3 engine in a Mustang or focus they want to replace with a 2.0. And here everyone wants a 2.3 to swap.
I say if you are gonna do it do it right and just get a build engine like the ecobeast or a Livernois short block. Strap on a maverick head and cams and never worry about it again.
