So the other night I'm driving to work, cruising about 110 on the Hwy. All of a sudden it feels like I have a flat, so I turn the radio down and drift around the lane thinking it was the uneven pavement but then I see the check engine flashing and I've got no power. So I get off immediately (convienelty there was a exit right there) and barely Make it around the exit and see a small parking lot. I pull in and scan the ecu and get a misfire in cylinder 4 code. I switch the car off and turn it back on and it sounded like a lumpy Subaru idling and I heard some metal grinding sounds. I immediately shut if off and called for a tow...two tow trucks later (the first one didn't have wood to load the car on the flatbed) I get back to the shop I do some part time work at.
Next day we pull the coils and spark plug and scope the cylinder and sure enough a piece of the piston is broken off and the cylinder walls are scratched. We checked cylinder 1 and it shows some small scratches too. At that point we parked the car and I left it till I decided what to do.
I called my ford service manager who is a pretty good guy when it comes to mods but he said if there is internal engine damage they have to call a ford investigator and if he sees any mods he will void the warranty. When I told him I had a fmic he said for sure they will void it. And if I put back oem stuff they would be able to tell. Problem is I could put the stock tune back in but I can't drive the car to get any drive cycles on the car. So figuring I would save myself two tows, one to the dealer and one back plus the money for the dealer to diagnose the car I would just build the engine with my mechanic buddies help.
Car is modded as follows:
Torrie 93 tune
3" carted turbo back exhaust,
Upgraded fmic
Eibach pro-kit springs
Mountune upper strut bar
And a few other suspension pieces
Car has 46000kms and is a 2013.
So now I'm trying to decide what is the best way to rebuild and prevent this from happening again.
Speed performance makes a nice rebuild kit with all forged internals
Dead hook Motorsport also has some nice pieces
Both are Mahle forged pistons and connecting rods
Sorry for the long Post continued...
