Got the Powerstroke purring again.
Been scratching my head and been super worried about some bad blow-by I was experiencing. Ended up tracking down an injector that was not contributing as it should, pulled it, and found that the copper washer had blown out and trashed the injector. Had a good suspicion that was the issue.
Finally got around to messing with it today and while cleaning the injector cup out, I noticed a SECOND copper washer chilling. Took a lot of effort to get it out, but there’s the source of all the issue.
New injector in, running like it should, and no blow by.
Got to finish up a few little details and get the injector coded but should be rolling coal tomorrow.
