They are two separate issues and not correlated as far as I know.
@ romin had these two issues back to back which may correlate them to those reading this thread but I'm not convinced that one caused the other. The detonation that leads to DI seal failure is caused by the older factory ECU tunes that didn't have transient ignition retard tables filled in past 5k rpms which allowed detonation between fast high rpm shifts and when the conditions were right (high cylinder temps, questionable octane pump gas)
P0351 and the #1 coil going bad is most likely related to excessive heat breaking it down over time since it's in a spot with lots of radiant exhaust heat and not a lot of air circulation. That's not a proven fact, but there's plenty of supporting evidence in this thread. |
The reason I believe they are somehow related is because both are happening primarily on cylinder one. Has anyone lost a coil on cylinder two, three, or four? I've only heard of a couple folks complaining about loosing seals on cylinders other than one and that was second hand knowledge via a dealer. I believe every burned seal photo shown on this forum was from cylinder one.
