recent (last week) and weird injector story...
I sent injectors out to cruzin performance for cleaning and rebuilding.

4 of these happened to come from a recently running car.
I saw their spray pattern with my own 2 eyes and they looked good..
however looks can be deceiving...

there is a static pressure test that tests for an internal seal.
this is a seal that can not be replaced during rebuild and if your injector fails this test there is no way to repair it....

remember that I saw 4 of these with my own eyes have a nice spray pattern.......


anyways out of 9 injectors shipped for rebuild.
8 of them failed and are not rebuildable.

I was blown away.
it surprises me how many of them out there are probably not good.

I'm not familiar how you would possibly test this on your own.
makes me very suspect from now on of used injectors.
I would highly suggest a reputable rebuilding resource.

sorry for the bad news
