OH that is a New Reman Inject???on #8 cylinder????????????
I think it is Bad if it smokes Bad like it did and then you Unplug it and Smoke Clears Id say thats Bad
You Can Ohm the Coils in that inject with Ohm meter there are 2 Coils each should be open to one another
Also you can Vac Test it when its pulled out It Needs to Hold Vac
Kinda surprised with the Smoke it Dont fail a Bubble Test

The noise my lifters made was intermittent. Just FYI. Not tryin to give bad news. But if its a lifter, especially on cyl 8. The rear cover needs removed. Then the cam needs to come out. That's if it's a lifter. I'd pull the lpop regulator 12mm hex iirc on the front bottom of the engine n look for metal.

I read through a second time and did not see it, but any codes? I forgot the code but when I had a stuck injector on #8 I got the code for contribution misbalance. My truck did the exact same thing. Any power loss?

Thanks for all the feedback, very helpful! Bowl was about half full when I did the bubble test (no bubbles). Anthony I'll check for metal, thanks. Btw did you get any bent pushpods? No codes at the moment even with injectors unplugged. I did have #8 contribution code before I changed the drivers side injectors.

I'd like to see a video listening under the hood during startup and shutdown. Not really gonna hear lifter noises until the shutdown. Unless its a catastrophic failure, then, well, you will hear all kinds of crap. The injector sounds more promising tho. But I think a lifter trend is happening.

Uploading a couple of videos now. Also I wanted to share a fact that might give us a clue: When I originally removed #8 injector it was the hardest to remove, the other 3 just came out no problem, while #8 was sort of tight all the way out. Same to install, #8 required more effort on the ratchet to reinstall. No power tools were involved. This is my only clue that might suggest a problem with the head.

For your entertainment:
Note: My comment in this video below about the quick start up is relative to the fact that it took a lot longer at 48v and one cylinder is not playing fairly.

Did the Bubble test over, no bubbles.
I recorded the test, video bellow, please note the miss during crank I know one of you guys can recognize this crank pattern in your sleep.
I'm thinking my next step is a compression test unless it's pointless for diagnosing this issue.
