As a casual user, I can not believe Brian was banned. He was without a doubt the most knowledgeable and prolific poster on this site. He responded to ever question I ever posted. Somebody F'd up.

I read the posts, and still don't know what (or where) the ALDA is. Does anyone have any pictures they could post to show? Thank you.

The ALDA is located on top of the injection pump nearer to it's rear, on the OM603 that's situated under the intake manifold and the three rearmost injection lines.

ALDA removal photos are here:
