Hello again. Been a while since I posted.

Having an issue where the truck will only run about 45 minutes to an hour before it shoots out massive white smoke, barely idles, and really cant be driven. Let it sit overnight, and you're good to go for a while.
No codes. Scanned with AE. Everything looks ok.

I am about to take it to the stealership (and I'm a professional mechanic, so that's how bad this issue is) but thought I would do a little more diag.

I pulled the valve cover off of the passenger side and watched with the engine running. I can see oil coming out of the spill port like normal, but one injector in particular (#3? Second from the front) will shoot oil out of the vent hole, towards the fender. All of the other injectors slowly dribble out oil, but this one shoots oil out.

What does this mean? What component has worn/failed to cause this to happen?

Thanks in advance.

p.s. Beans 160cc injectors about 4 years old.

What is the vent hole? Is oil coming out around the base of the injector? That would indicate a bad top injector o-ring. Cheers!

Those little holes (one on either side). The large one is the spill port, where oil should normally be coming out of.

Armature plate is tight against the body. I did rotate it 180* and found that it was much tighter after rotating 180. Rotate it back to where it was and it was easier to turn.

Rotated the armature plate 180 and it stopped the leak... Lets see if this fixes it.
