77 450 SEL (Euro) vacuum advance line loose and off(*Steve or Benzmac)

**To Steve and/or Benzmac:

I have a 77 450 SEL euro version, with the hot cam.

Some weeks back, due to my own carelessness, the short (red) line from the vacuum advance (on distributor) came loose from wherever it disappeared to on the underside of intake. This is the short red line, about 5-6 inches in length. I've looked at the Chilton guide, and the diagrahms are for Fed. and California U.S. models. I don't trust them.

PLEASE........can you possibly describe, if you know, EXACTLY where the hidden-end recepticle is, and how I can best get there without removing things?

The more precise information you can give me, and any 'tricks' as to getting it in there, will be SO much appreciated!!!

Thanks........

Bob

Can someone intimate with this line and where it goes advise on this? Although I've compensated by retarding timing a bit, the car runs just that much quicker and better with the advance properly connected.

Please!!!!!

Thanks.

Bob

Bob,

You need two things. A 12" pair of needlenose pliers and a flashlight.

Use the flashlight to illuminate the underside of the intake, once lit you should be able to see the pipe nipple the line goes to. Once you see the nipple, it is simply a matter or using those long needlenose and a little finesse to slip the rubber back on the nipple. The long neddlenose let you reach way in under the intake, but check closely, you may have to pull the distributor cap to have enough room.

PS: all the vacuum ports should be on the port side of the throttle body.

To Mike Tangas:

To Mike Tangas:

Thanks for your description.

1. Where can I probably find inexpensive 12" pliers? At Sears, Auto Zone, Advance, etc., all I can find has been the 8 inchers. I'm sure the 12s will help.

2. The rubber nipple (small, bent elbow) is broken off at top from my futile attempts.

Can I get this part at MB dealer? What's it called?

3. Since my lines are now disconnected, I forgot which line from advance on dist. goes to which port. Can someone describe or diagram for me?

Thanks a million.

Bob
