Metal on ipr valve
 

So as the title states, i have metal on my ipr valve. Truck currently has a miss in 3.. i first changed the injector in 3 because i thought that was my issues. Didnt help so i scanned again found miss in 3 and Slighty in 8. pulled the ipr. I didnt do that first because i just replaced it 2 months ago. Found the metal. So my question being is the hpop eating itself apart? And if so would that metal spread to the rest of the motor. Not sure if i can just swap the hpop out. Looking for help asap. Thanks!

could be the HPOP, it will spread some metal around. the IPR will catch some of it and some could get caught in your injectors causing a miss.
