Well as of yesterday my truck started knocking... It sounds like an injector knock as described by forums I've read and videos I've listened to. I pulled off the passenger side valve cover tonight so I could unplug each injector individually to see if I had one going bad. Well that really didn't get me anywhere, the noise is from cylinder #1 and it quiets when the injector is first unplugged but then it resumes. I was almost certain it was going to be injector o rings since recently I've had a cold start problem, I've noticed some blue smoke coming out of my exhaust at idle and there is a lot more oil coming out of my ccv and seeping into my intercooler boots since the noise has started. Now I'm thinking the worst like a valve or connecting rod or who knows. Any advice will be greatly appreciated, I can post some videos too if someone could tell me how to. Thanks

Here is a video of me connecting and disconnecting the injector, it's hard to hear but there is a change. Also my concern is when the truck shuts off at the end you can hear the knocking noise slow down as the engine slows down which I don't think an injector would do. The mistake I made during this video was having my truck in the stock tune, when I turn it up and unplug cylinder #1 injector it stumbles but then idles normally other than the knocking sound, every other injector I unplug it stumbles then idles rough until that injector is plugged back in. The noise is the loudest at cylinder #1 too so something is going on in that cylinder or injector I believe
