(I think the older cars used more solid colors, I didn't experiment with ordering those.) I found on the EPC that the same part number can have a different description depending on what chassis you look up. Some chassis have more info than others. For a list, go to the "Intake & Exhaust Manifold" group in the engine section, then look at the general parts diagram. Try this with several chassis (123, 124, 210 for example). I also found out that the pictures don't always match up, and some may appear identical but can have widely differing sizes - which is often NOT mentioned in the EPC! So I've been ordering select items (1 each) to figure out what's what.

Unfortunately some parts have rolled to generic replacements, so we can never return the car to "original" condition. For instance, gray pipe was replaced with black, the brown/blue (for I/P shutoff circuit) has also been superceded to generic stuff, as well as the black w/white stripe to the transmission. The hassle with this is that the colors actually MEAN something, and when you use plain items instead it can be confusing. Black is normally a vent line to the interior, and MB has seen fit to supercede some p/n's to black. OK, enough rambling, here's the currently available p/n's that I've confirmed:

Vacuum line ("plastic" Tecalan pipe, 4mm OD, 1mm ID)
=====================================================
000-158-14-35 - Transparent (sort of white)
000-158-35-35 - Red?
000-158-88-35 - Transparent with brown stripe
000-158-89-35 - Transparent with red stripe
000-158-90-35 - Transparent with yellow stripe
000-158-91-35 - Transparent with blue stripe
000-158-92-35 - Transparent with gray stripe
000-158-93-35 - Transparent with black stripe
000-158-94-35 - Transparent with green stripe
000-158-96-35 - Transparent with violet & brown stripe
000-158-97-35 - Transparent with violet & red stripe
000-158-98-35 - Transparent with violet & yellow stripe
000-158-99-35 - Transparent with violet & blue stripe
000-997-39-52 - Brown
001-997-81-52 - Black
116-276-06-30 - Black with white lettering
123-276-16-30 - Black with red stripe


Rubber fittings & hose (3.5mm ID)
==========================
117-078-02-81 - 90-degree "L" shaped fitting
117-078-05-81 - 45-degree "V" shaped fitting
117-997-09-82 - Rubber hose (order by the meter)


Black "loom" (looks like heat shrink tube)
===========================================
040621-008200 - 8mm ID
040621-011200 - 11mm ID (most useful on my car)
040621-012200 - 12mm ID
040621-014200 - 14mm ID
(notice the pattern here? Larger & smaller are available too...)


Branch fittings (splitters)
===========================================
601-078-02-45 - "Y" shaped 2-port branch fitting (1 in, 2 out)
601-078-04-45 - "Y" shaped 3-port branch fitting (1 in, 3 out)
601-078-05-45 - "Y" shaped 4-port branch fitting (1 in, 4 out)
601-078-06-45 - "F" shaped 2-port branch fitting (1 in, 2 out)

The boost pressure line on the OM617's is larger than the vacuum stuff. The OM60x engine boost line is the same as the vacuum stuff (4mm OD). Anyway:

617-070-07-81 - Line from intake to s/o valve
617-070-06-81 - Line from s/o valve to ALDA

They're relatively cheap, and I think they include the metal fitting on the end.


Most of the pipe & loom is $3-$5 per meter (had been much cheaper, but MB is trying to make a bundle on parts now. :mad: ) If you haven't replaced them in your car, it's a good idea to just do it. Total cost is probably less than $40. It's amazing how much of that stuff snaps like twigs when you start removing it!

Then replace the cylinder head so everything has to come out, then go nuts with a rag and WD-40... and replace ugly parts with new, like the platic coolant tank! (It's starting to turn that nice yellow color already, 2.5 years & 20kmi later...)

:D

Here's another teaser from back then... it's not as clean now, I actually drive it, so it's kinda dusty...
