Does the body of the Injector pass through the Rocker area 'naked'?

Yes, the injector passes through the valve cover, through the 'rocker area' naked, and then into holes in the head with a smaller hole at the bottom for the tip to spray into the combustion chamber.

The injector is made of 2 or 3 sections crimped together with seals.
I have heard of the bodies of BOSCH piezo injectors leaking on other cars but not Audis, but as our cars get older it is more likely I suppose.
