OM 606 idle miss and excessive blue smoke
I also noticed that i was getting some leakage out of the injector return barbs. I know they are there for a reason, but does anyone have an idea how much is expected? my understanding is that this is from leakage internal to the injector on the non sealed surfaces, but that said, if the IP is sending a metered amount of fuel, there shouldn't be a ton coming out of these lines or the injector wouldn't be getting the proper injection qty correct?
Still waiting on my prechamber tool, but i'll post up any findings if/when I do get them out.
injector # - compression test (psi) - injector pop (psi)
1- 365 - 1975
2- 380 - 2025
3- 375 - 2010
4- 380 - 1980
5- 385 - 1990
6- 365 - 2020
haven't seen a compression test spec, but these seem to be a reasonable range and close to what most people are seeing. The injector range is 1958 - 2030psi from what I've seen.

While the number consistencies seemed reasonably close to what they should be, i did notice that my number 4 injector would start to pee a stream of fuel at 1900psi if I approached the pop pressure slowly. I'm going to replace that nozzle and see if it helps.
