Ecoboost Engine Blown?

Joe why do you think you had a bad engine from the beginning?

I had the car back to 100% stock. They knew it had been modified they said they could see it when they plugged into the ecu even when I had did the key cycle thing 100 times or more.

For all who are wondering what happened with my car, the motor blew up

That's terrible to hear :(

What octane fuel were you running? What gear were you in when you floored it?

Not sure what gear just merged on the highway when I floored it to pass cars and it happened. I was running my 93 tune with 93. I can't be sure that the engine was bad from the start I'm just assuming.

Wonder if it was the same piston/rod that blew on Mattrix's motor here in this thread.

It was the 3rd spark plug in when looking from the front on the motor towards the inside of the car. So is that cylinder 3? Regardless it should not have blown with only 7000 miles on it

Mattrix's might have been cylinder #2 from the front based on the photos in his post (not 100% sure though). Looks like the cam phasers are on the front end of the head ... if so, then looks to be Cly #2 that blew on his engine.

The reason I'm trying to see if it was the same cylinder is because if so, that might mean there is a flaw going on with the motor.

Not sure if I reached 6th gear at that time or not. So not sure the gear either 5 or 6 I guess

LSPI might have been the culprit. Out of curiosity, what oil were you running?

yep LSPI was one of the things i was concerned about when i had my wrx. i never, ever went WOT at low RPMs while in a high gear for this reason.

Dealer changed oil in the car so whatever it calls for from the factory. And that ridiculous that you have to downshift just to floor it. I had an automatic so I shouldn't have to downshift to floor it. Either way it's my fault I did the mods knowing that something could happen but I was not expecting the dealer to be able to trace the tune after following the advice on this forum. Not blaming anyone so don't take that the wrong way.

yeah i know, i found it ridiculous too. it was my first turbo car and i had no idea. i went WOT while in top gear (5th) all the time before it was fully bolted on and it was fine. i had no idea it was bad for the engine.

but when i started modding the car, i researched the hell out of everything and that's when i found out that it's REALLY bad for the engine to go WOT at top gear.

I really like you're handling the situation, taking the blame and not blaming anyone else.

You did everything possible that was discussed on these forums, going back to stock, key cycles, etc. and in the end, it didn't work. I'm very sorry that it happened to you and other people should def. learn from this. The "Tune" is the number one mod with the Ecoboost and unfortunately, it is the one tune where if something catastrophic were to happen, you will have to foot the bill to fix it.

In other words, if you don't want to foot the bill for a new engine, don't tune your car. It's def. a gamble since I seen stock engines blow up and they will blame your tune.

 

[ypena02]

LSPI can blow up a completely stock engine as well.

 

[Asharus]

yeah but what do you do if you have an auto car like joe does?
