The rubber, fabric-covered lines are RETURN lines; the bent steel ones are injector SUPPLY lines. ;<)

You mean the bent metal lines to the injectors?  Or the flexible
rubber/cloth lines between each injector?

be careful what you "clean the engine" with; the stock return lines are
pretty easily destroyed by many engine degreasers and cleaners.

    i didn't see how long it's been since you replaced the ones that are
in there, but frankly, i'd just replace the return lines all with known new
good lines; it's the quickest/cheapest/easiest possible solution, and on
the off chance that it doesn't solve the problem it's the easiest way to
eliminate them as a possibility of the cause of the leak.


cheers!

Great input - thanks.  Clearly, I need to clean the engine and watch for
the fuel to appear. The cloth injector lines are pristine; in every other
case of leaky lines they were saturated (dark colored).  Mine are still
dry
and white from one end to the other.

This is a CA version 1985 300TD - could that have something to do with it?

 If you don't have any luck with the return lines as other suggested and
you

go for replacement, then replace all the injectors. Or better yet, have
them rebuilt by someone competent.

But avoid those Indian bosch rebuilds, they're really horrible. I just
confirmed this in a 240D I bought a few weeks ago... the car ran very
poorly, nailing and knocking.  The injectors looked recently installed
as
they were very clean. They tested ok on the pop tester, but I rebuilt
them
with new nozzles anyway.  Huge improvement.

Good luck,
Jaime

 I've seen compression leaks when the nozzle seal/heat shield is not
seated
properly, and leaks from the lines and from the return hose, but never
from
the body of an injector.  If the nozzles and nozzle holders are
un-fiddled
with, then you are looking at hoses as the most likely source of the
leak,
(99%) If someone has recently fiddled with the Nozzle holders, the they
may not have been assembled correctly and could be leaking.
