Hello,
I have a problem with my AAZ engine, it leaks diesel from the ADL (I assume the "champignon" on top of the injection pump is called so?) breather opening.

I have opened the cover, from which a small hose goes to the intake manifold, so I guess that the turbo pressure goes on the upper part of the membrane, and moves so a lever or so to regulate the amount of diesel injected?

anyway, I opened the cover, membrane is still in one piece, nor rips, and upper part is dry, no diesel there.

bottom part, a complete different story, completely filled with diesel, so that it even leaks out of the breather opening.

Where can I find the culprit? and what do I need to do to get this repaired?

any help on this is more than welcome.

 
Thanks, Bart
