Hey, I'm tracking down a vac leak, and I founf that one of my oil injectors are leaking. When I dug around in the shed, I found injectors, but they are longer than the ones in the LIM. (TII S4, btw). I have torn down a couple of S4 N/A's and my current TII motor, are these N/A or Turbo injectors? Is there a difference? Which is which?

 

the long oil injectors go in the manifold.. the short ones go in the aluminum housings

 

Just to clarify, this is on a turbo. They just look so long.

 

I checked the short ones. When I apply vac to the nipple, it slowly leaks out.
