We accept the fact that heavily tuning our engines may in fact have catastrophic consequences even if we all hope it never happens.

I remember reading a lot of threads of stuck/failed injectors on here when I was doing initial research. I feel like we haven't heard much recently but it does seem to be somewhat of an issue. |

Well I hit the cyl with a “bottle brush” hone and they have a nice cross hatch, got a ton of goodies coming for the build now. FYI - Finding main bearings for this is a effing NiGhTmArE!!! Got the crank decoded and have the color codes but none of the dealers know how to look them up or they are showing discontinued already... |

This isn't the first report. Has happened on stock motors as well.

☝️ He ain’t wrong...
I’ll also add that there were 0 physical signs of pre detonation in my case so it’s hard to believe it was tune related Cyl 5 was definitely being over fueled to say the least... |

Any early warning signs we can look out for? How did that plug look?

It looks like just a manufacture defect or weakness combined with running high boost on a cast piston. The two factors converged. There is no scoring of the cylinder or anything showing foreign matter and no detonation. I can't see cylinder 5 closest to hpfp having been a factor either since fuel is nearly in-compressible.

Like the other guy said probably a number of factors converging to create “perfect storm” |

Seems like a pretty low failure rate but maybe you have more information from another source that I'm not aware of.

Nice man. Are those the 82mm or 82.5mm pistons? And what rod bearings did you get? Do they come with the coating that the original ones come from the factory?
