I used the spot pointed out in this thread here:
http://www.audizine.com/forum/showth...=1#post2410777

to attempt to seafoam my engine, but there appears to be no vacuum there, and even if I try to pour it in, it has no interest in going in?

Do I have a deeper problem? Or am I misled by this post and need to use a different location? My engine is currently running fine, but I just thought I'd give it a little cleaning with some seafoam.

This is on a 2001 A6 2.8 30v

 

Ok, I figured out that the hose pointed to in that picture is incorrect. It's one right next to it. I started pulling a couple of hoses and found one right next to it that had a lot of vacuum. It worked like a charm
