[Vwdiesel] Bubbly injectors - uh oh.

[Will Taygan]

More on the bubbly injectors:

The injectors themselves are old but fine.  I had the pressure re-set to 130
bar and the bodies don't leak.

I cleaned the threads and seating area with a pick to get in the tight
spots, and yes, I pushed the gunk in too.

I already replaced heat shield #1, It looked carboned with little chunks
from only a few miles of driving, but the space between the injector and the
head (the injector socket?) was squeaky clean!?  Strange.

The bubbles are definitely coming from the head-injector seal.  I don't want
to use any compound that will permanently lock the injectors in there.

The PO had used some other kind of heat shield with a larger opening (I'll
measure it later today.)  This other heat shield seems to have helped on
cylinder #2, but not on cylinder #1.

I found the bubbles because I was bleeding the injectors, and diesel was
dribbling down onto the head.  Only one was bubbling at first, then two.
Humph.

I'm a bit worried that I'll make it worse by driving it around.

Thanks,
