Part removal question?
 
Theres a plug to the left of the ALDA and right above the shut off valve. Its an electrical connection of somekind how do you remove it? I don't want to break it and have tried twisting, pulling but it wont come out. The cars a 300SDL.

There is a collar on the outside of the round plug - there should be a tab on the collar. Rotate the collar counterclockwise using the tab for leverage and them lift the plug straight up. As I recall you have to rotate the collar about 90 degees or so before the plug can be removed.

Why are you removing this connection? Are you taking the IP out?

I can't get the shut off valve out without removeing this thing. Unless someone knows of another way.

Dave M/gsxr has a post with pictures that shows how to remove the ALDA without removing the intake manifold. Remove the ALDA and you'll have no problem removing the shut-off valve.

Fellow 603'ers,

Removing the intake manifold isn't TOO bad - it just takes some good hex sockets (1/4" drive Snap-ons work well), some wobblers, extensions, and of course a ratchet. When it's off, you can do all kinds of fun stuff EASILY, such as:

Replace glowplugs
Replace shutoff valve and gasket
Lube throttle linkage sockets
Adjust ALDA (can be done w/ manifold in place if ALDA is removed)
Replace injector line clips and rubber shims to prevent injector line damage
Replace intake manifold gasket which likes to leak around the #2 intake port
Clean intake manifold of 16+ years of sludge

You should do all this eventually, and removing the manifold allows you to accomplish it quite easily.
:D

Two questions. What is that plug? Also is the ALDA supposed to hold vacum? If so how much? I sucked on mine and it didn't hold any vacum? (that sounds good:D)

The plug is for the control rod sensor input to the EDS. Wait for your manual!!! :)

I was told not to apply vacuum to the ALDA. I was also told that vacuum integrity of the ALDA says nothing about how it will perform.
