2003 Cl600 V12 Twin Turbo. I changed my Crank Shaft Position

Customer Question

2003 Cl600 V12 Twin Turbo. Hi, I changed my Crank Shaft Position Sensor. In the process I found my vacuum line cracked. There is a black rectangle box just under the intake manifold that has two vacuum lines going to it. I have pictures. I had to use an
endoscope camera and found the plastic broken off in the rubber hose clamped to the black box. I've already taken out the turbo intercoolers. Do I take the intake manifold out now or..?

Hello my name is***** you asking what order to disassemble the engine in to access the box? I have not personally had to dig this deep in a v12 but can assist if you need factory instructions ? Let me know how you want to proceed. The pictures you have supplied are excellent by the way.

Hi Lou, Well... I want to be successful. I'm unafraid of anything mechanical and I would always reach out to seek the knowledge but in this case I don't even know what that is called and I cant find anything on it.. I believe it to be a vacuum source but I'm not sure. My thought was to not be stupid and take it all apart only to have someone such as yourself say.. oh no.. you don't do it like that :) So yes I'm willing to take the intake out and what ever else to get it right if your willing to guide me. Thanks, Mike

Please take no offense but perhaps opt out..? I think the purpose is to have a "Been there" perspective. Would like to validate that I have to take the entire intake out to get to that hose. Additional documentation..? I can view what you presented online (for free) with the link below. Perhaps I should have bought the manual to wing it.There are quite a few steps before you can take the intake out, each with its own procedure number.1Remove intercooler AR09.41-P-6817HH

It is a vacuum Tank...! All the way from Japan I found the document.
Customer: replied 1 year ago.
here is what i did. Rather than risk the take apart ( meaning you might break a bolt or drop something :) ) I found a tank on ebay and will connect the lines to it mounted somewhere close. For those out there that may need, the part number is ***** The call it a Dashpot:( vacuum tank) .
