Injectors still pees after nozzle replacement

[300SD90]

Hey all,

I cleaned all of my OM617 injectors and replaced the nozzles with Monark's. Here are the pressures:

PSI
1: 2050 (previously 1950)
2: 2025 (previously 1950)
3: 2050 (previously 1900)
4: 1700 (previously 1750)
5: 2100

Obviously #4 needs to be shimmed. Some of them started to pee when I first starting pop testing them after the rebuild (I was told this was due to the film on the new injector nozzle by another helpful member) but #5 is what is worrying me.

If I hold its pressure at 2100, I can get it to pee a stream directly down and to the side. It DOES NOT happen every time, but I can make it happen after a few tries. From what I read from previous posts, this is okay because this is not how our IP works, and testing should only be done with long strokes from the pop tester.

I made sure that there was no debris when reassembling the injectors, and did not remove the pintle from the nozzles. One did fall out, but I lubed it and gently let itself slide into place. Is the peeing of the injector as described a "no go?" What would cause this? Over tightening of the injector halves? I did use a torque wrench but anything goes I guess.

Any help is much appreciated.
