so I'm still trying to cross off all possible sources of vacuum/boost leaks on my s4 T2. I'm currently getting some new pintle caps and grommets for my Bosch 1680 injectors. I also want to verify that I do not have a problem with my fuel injector air bleed sockets, especially the o-rings. Here are pics from Mazdatrix of the injector air bleeds:


"primary top"


"primary bottom"


"secondary"

My first question is, in these diagrams which way is "up" ? which side pictured here fits into the manifold, and which side does the injector sit against? Second, do the primary injectors sit against what appears to be an o-ring? How do the two piece primary bleeds fit together? I just want to make sure that I am not missing something stupid that could cause an air leak.

In the bottom two bottom pics, the "top" is on the right side in the picture, the little cheese grater end goes down, I thought they were called injector "mixing-plate sockets" though. They fit down in the holes for the injectors themselves, they help atomize the fuel.

I personally didn't notice the two pieces to the primary but from a book i have it looks like the first piece fits over the bottom of the primary mixing-plate socket. I'll post a scan in a minute.

here ya go:



hope that helps you.
