You can see in the pics you have a slight ring in the steel of the plunger body bout 1/2 in up from base of tip. That tells me your getting a good seating on those. There is a couple that look to clean for a better word. Like swaan said it only takes one to cause the problem.

Oxbow and Superhauler Thank this.

I'm wondering if the injector cups are screwed up on a couple holes. Not letting the injectors seat proper ?

Then I'm leaning toward seats. I have pulled injectors out after 100,000 miles and still have most of o-ring still intact.

I'd have all 6 seats cut. Believe it or not this is quite common around here.
We got a guy here at a local fuel shop that made his own cutter just for this. All the local shops hire him to do this job in house.Oxbow Thanks this.
