Hey All,

After pulling all my bank 1 injectors out, I was left seeing all of this on the ends of the injectors that I have pulled out, looks like sandy, dirty oily ends, it feels like sand to be honest which has gotten me worried šŸ˜¬

I've pulled the injectors in both my cars and neither looked like that.

Your seals look like they've perished.

Agreed.

Never seen injectors look like that and I have pulled a few seperate sets from various n54s.

Replace with new index 12s and move on with your next mods is my vote.
