Message: [QUOTE="Zeb, post: 1510340, member: 30304"] That is the best place to measure pressure, and you are using quality parts to do the measuring, so I think starvation has been ruled out. I think it is most likely a nozzle quality issue. There is the chance however, that the sprin cage is worn and that allows too much pin travel. I saw that on a set of 190/30,s that I built from Alliant Power cores (they seem to be the worst for spring cage wear). I built the injectors, and a couple months later sold the truck. About a month after I sold it, it cracked a nozzle. It had 0.004” deep wear pattern on the bottom of the spring cage. Replaced it, and 2 months later another cracked nozzle. I told the boy to send me all the injectors and low and behold, the injector with the cracked nozzle had 0.004” deep wear, and 5 others were 0.002-0.003” deep. Replaced all the worn cages and it has been nearly 2 years and no more cracked nozzles. [/QUOTE]
