Would This mean it’s one or all of the front 3 injectors right?

Yes

Yes.......

it's possible you have a bad timing or metering actuator for the back 3 since you've found an issue on #4 but no bubbles.

Also look VERY close when barring the engine over, "bubbles" can be easy to miss. Watch Rawze's video(3 short videos) and you'll see what i mean.

Thanks to Rawze and his videos is the only reason am even messing with any of this.

What do you guys think is this too much oil on turbo side feels caked up little wet.
