Hi Matt, what is LSPI?

From Wikipedia (which I usually avoid), but a decent succinct definition:

"Low-speed pre-ignition (LSPI), also known as stochastic pre-ignition (SPI), is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge. LSPI is most common in certain turbocharged direct-injection vehicles operating in low-speed and high-load driving conditions.

LSPI events are random and infrequent, and their effects on impacted vehicles can include very high-pressure spikes, loud knocking noises and sometimes catastrophic engine damage."

Dilution of the fuel mixture is often a contributor. This is why you see a lot of oil companies moving to new blends/formulations to help prevent this and a lot of people running catch cans, etc.

No I'm thinking the dealer whos ripping him off. Example the money he shelled out for diagnostic and the posted photos they gave him.

He didn't "shell out" anything- he already told us his tuning company paid for the entire repair...

He paid $1,600 out of his own pocket to the dealer. It's buried back on page 400. ?

Hi Rick, I’m not keeping the motor, but I am paying the core fees for all my aftermarket parts, so that it helps 5 Star... thats a good idea about the engine to 5 star, I’ll see if they’re interested in having the motor... unfortunately, Ford just tells me, ”all the mods”... I’m just going to believe that Ford will never tell me what caused the failure, and will hide behind “all the mods”... I wasn’t tweaking a tune, I just purchased a standard 93 octane tune, and was happy with it, and I’ll be buying another one when I get my truck back, plus reinstalling all the AFE parts once again... It’s just been a damn headache, and I want my truck back ?

Your comments confuse me. You've talked now for weeks how you think it was the oil pump and that it wasn't your mod's.

The photo's show that there is damage inside the combustion chamber. That's not oil pump related.

Ford isn't obligated to "tell you what caused the failure"... Rather you agreed to pay them to determine if the failure is under warranty. They did that. You modified the truck way beyond the original configuration with the tune. And that tune is also way beyond Ford's tune that has a warranty. If you put an 8-71 blower on the motor and ran nitrous and it grenaded, would you also expect Ford to honor the warranty?

LSPI and knock are well known issues with these motors if the tune isn't correct. You modified the tune.

Stop bashing Ford. I was in your camp but at this point you're coming off as a whiner.

That has to make you wonder now if the fuel in our oil that many are seeing isn’t a contributing factor to this. It isn’t just one thing, it’s a combination of factors adding up to make the perfect storm

Whenever I hear someone who is on sketchy ground, challenge the dealership with some variation of the phrase "Well aren't you going to HONOR YOUR warranty?", it strikes me as one of the most "Karen-y" things a person can do.

First of all, it's not the dealership's warranty, and the dealership is not Ford. The dealership is a private business, contractually obliged to administrate the warranty that Ford offers on their vehicles. So it's probably not in your best interests to create an adversarial relationship with the dealership employees that are trying to help you, by squaring off with them.

Second, "honoring" a warranty does not mean just giving you free stuff for no reason other than because you just want free stuff. Sometimes, "honoring" a warranty would mean giving you nothing for free, and charging you full retail for everything.

I think a lot of the misconceptions about warranties stems from a fundamental ignorance of what a warranty actually is. Ford tries to do the best they can, but they never claimed to be perfect. So they offer a warranty to give you a reasonable amount of time (usually expressed in miles and months), to discover any manufacturing defects and present them to the dealership so that they can be corrected.

The reason that warranties are not forever, is because Ford feels that at some point, YOU need to take ownership of YOUR vehicle.

Warranties are not designed to immunize you against all adverse aspects of vehicle ownership- as I stated above, they are only designed to correct manufacturing defects, not things that YOU do to YOUR vehicle.

I'm not happy about having to read through 25 pages to confirm my original suspicions, but to anyone with a good working knowledge of these types of matters, it is not surprising that Ford is not participating in this repair financially- OP buys a truck, modifies it with big tires, aftermarket intake, aftermarket exhaust from turbine flange back, modifies the engine management software to run on the ragged edge of the highest octane gas available out of a pump, and then AFTER the red oil pressure warning light comes on and it starts making noises clearly indicative of a catastrophic engine failure...he continues to drive it until the engine seizes up solid. Do the math...

Did you ever actually talk to someone who works for Ford, or just the dealership?

Yes, Ford re-dirctected me back to Mac Haik... I’m tired of the the bull shit... “I’m WOKE!!” Lmao... I’ll give you cash if you give me my truck...

No. He didn't pay anything- he AUTHORIZED up to $1,600 for diagnosis, which would include tear-down if necessary. Once they boroscoped the engine and saw that it was toast, there was no point in tearing it down, so neither he nor his tuner ever paid any $1,600 for tear-down. I would speculate that at the most, there would be a couple of hours of D-time flagged. 2 hours at $125/hr, would be about $250...

Yep. I have seen some Mustang Ecoboosts and Mazdaspeeds fail because of LSPI. It was kind of discovered as a huge issue with GDI turbo engines in a racing series in Europe that used new Minis. It is the main reason that I went to a different tuner as well. Although Ford says you can expect a little pinging due to how these engines control detonation with knock sensing and OAR, I try to avoid it. I have found that using a good booster like Lucas or even a splash (1-2 gallons) of E85 on a full tank will help if you start hearing it. I actually put the Lucas booster in every tank (mix 1/2 bottle for each full tank to last for two tanks) and go to the same station for fuel that I have had luck with getting good gas. But I went with another tuner because even that did not help. Now it seems fine, but I am very cautious.

Ironically, even if his modifications hadn't caused his engine to fail, Ford still wouldn't have covered it, because once his engine oil pressure light came on, once the engine started making noises, he had an obligation to not do anything to damage it further.

Choosing to instead drive it all the way home, until it seized up, made this completely his responsibility.

He should be thanking his lucky stars that his tuning company offered to pay for what he did to his engine...

Project Midnight, did you run colder plugs? Not sure how much it would have helped if this was LSPI, but it wouldn't have hurt.

No sir, never changed plugs etc.. and I apologize for the rant on sheepdog... I’m trying to keep it cool with all the attacks from everyone... but I’m losing control..

 

[TORQUERULES]

I agree that he shouldn't have driven the truck as soon as the light came on and the sounds started, but honestly the damage might have already been done and it would not have mattered. From the look of those borescope pics, things went south quickly. It is up to the owner at that time to make the right decision. So I have nothing to say about if what he did after was right or wrong, because I wasn't there, but I probably would have stopped. Again, that is me speaking from miles away. He is just lucky both warranties were not voided. I can understand him singing the praises of Stage 3 because of their support.

Although many people do not change them, it is added protection. Maybe next time.

...and I apologize for the rant on sheepdog... I’m trying to keep it cool with all the attacks from everyone... but I’m losing control..

Apology accepted.

And it wasn't an attack, buddy- just an observation. I'm as happy as anyone that things are working out for you...
