I am new to diesels and new to this forum this might sound off the wall but were the heck is this banjo bolt that needs cleaning on a 1984
300d turbo? I have looked and looked but can not seem to find it.

Also the ALDA is right there where you can get to it is there any need
to remove it to adjust it? From what i am reading the adjustment is right
under the plastic cap on top right?

Thanks For The Help..
