I was told some years ago to "not bother" about valve adjustments in the Diesel unless there were "obvious" problems, since the adjustment is fairly arduous involving spacer-disk placement/replacement rather than a conventional tappet adjustment. This was with a youngish Jetta at the time (`81, 60K miles). Of course, I never had any such obvious problems... and my `82 Diesel Vanagon with 88K miles has never had a valve adjustment to my knowledge either. > 1) The first "injector" is leaking diesel from the threads (YECH!). > Couldn't get a wrench on it.

In any case, I'd take care of the injector leak first before attempting to diagnose/prescribe further "performance" problems in a Diesel, performance being a relative term.
