I recently did a smoke test on my W210 and found three vac leaks.

First was the oil cap. Thats easy

Next there is a wierd little rectangular box that comes off the Intake boot. The 45 elbow that connect the box to the boot is leaking. I have no idea what that part is called or the part number.

Finally, there is a hard plastic vac hose on the back side of the intake manifold on the drivers side. It is leaking where the plastic connects to the intake manifold.

Short of calling the dealer, how can I get these parts?

You are talking about the resonator I think.
Have a look at the link.

You can get the whole air intake flow tube with the damper (resonator) for 60 bucks.

The hard hose is either for the brake booster or the EVAP purge valve. Follow through the hose and see where it goes to.

If that's your first time replacing the brake booster line.... hoo boy. You'll be in for a fun time.

Here's a hint: the middle portion can be removed. The plastic fitting thats right on the intake cannot be removed from the intake -- it is part of it. The other plastic portion with a little tab on both side? That is the removable part.

Ask me how I found that out.

okay, that list is quite helpful.

When I did the smoke test, a decent amount of smoke came from that fitting. Am I correct in thinking that I dont really need the hose? I just need those three parts so that i can refresh the o ring.

You will not know until you get hose out. Clamping rings has sharp teeth that damage hose when removed forcefully.
