Stuck injector? Now what?
Only thing I can think of is a stuck injector. Any remedy besides new sticks?
bare with me while I remember how to upload a video, obviously attaching it doesn’t work.

maybe that works?

only way to check is pull the injectors? What would cause a cracked tip?

I cannot say it IS a cracked tip, but that sound and cloudy exhaust is strong indication of way too much fuel injected each time it's called for in the Otto cycle. Only way to fix that is to figure out the offender and replace it, or just bite the bullet and do them all.

A HEUI injector cannot get "stuck on" and inject fuel constantly like a common rail injector can.
I'm with Kwikkordead. I think you have a nozzle issue and continuing to drive it like that will cause piston damage.

A bad injector can inject fuel with the pressure of the fuel pump.

Ok, thanks… really only had my last set from Full Force to compare, had 150k+ on them and still strong before the truck decided it was too cold outside 😂 (see sig picture)
