I know this is gonna sound stupid to you seasoned mechanics out there, but is it a big job to remove the manifold?
Any tips?
Special concerns?

(It seems like on these MBZ's, there are peculirarities that make a simple job on other cars much more complex.
I just replaced my IP shutoff valve successfully, thanks to this awesome forum, the warnings and tips were much appreciated.)
