(06-18-2020, 02:16 PM)zeemanThanks for those. Unfortunately this is the 3rd time I've had the injectors out so I've got those other 2 haha. I added the new nozzle on #4 and it fixed the "peeing" at 1900psi. I lapped the internals on that one too and was interested how it now had the machine gun firing pattern. I didn't know if it was the nozzle or the lapping/better internal sealing. I lapped the internals on 2 others and it didn't change (no machine gun pop action). How do yours fire?X Double Dot Just pulled the prechambers, they all had the ball in there. Couldn't find any cracks or issues with them either. I'd post a picture but this site won't seem to let me.130 nm Prechambers
just slid them all back in (after cleaning everything) and will start redoing that nozzle now. anyone know the torque spec for the prechamber retainers? Lots of info for the older style but haven't been able to find anything on the 606 *edit, looks like 130nm for the splined style on a om602, i assume those are the same?*
40 nm injectors to head
70-80 nm injector body
I repopped the other 5 again and noticed on 2 others that if I held them essentially at the pressure that they were just about to fire at, that they started to create a droplet if I held it long enough. Obviously the engine doesnt really apply the pressure rise slow like this so I'm wondering if it matters. Those firad 314 nozzles only have about 3000? Miles on them so they shouldn't be worn out...but it has me wondering if I got a bad batch.
