In Reply To	Causes of injector failure. posted by DVDBURN (MD) on January 18, 2010 at 06:14 AM
Message	First, the entire injector is assembled via a 'drop in' method. Every part is dropped in from the top of the injector body. In my cutaway injector this can clearly be seen. The 'spring guide' is actually just a copper plug. Out of the eight injectors I had fail not a single one leaked out this seal. Second, the pintle assembly picture you have isn't very good. Here's a better one: It does not use a rivet to hold the cap and body of the pintle together. I believe them to be a press fit or possibly bonded before final machining of the cap. Third, there are a total of 4 o-rings inside the injector body. "The 300ZX Turbo is a dance; it's a song; it's rolling, roaring automotive art. There is no color that doesn't suit it. There is no mood-lifting chemical substance it can't replace." - Automobile Magazine
