2004 S80 NA - Vacuum line for Seafoam

[dejongmc]

Hi guys,

So I took a closer look at my engine based on the information above, and it looks like my engine does not have the banjo bolt. At least, I was not able to find it.
Here some pictures from underneath the intake manifold.

Under intake manifold

Also, here a closer view of some vacuum lines (I think) at the intake manifold.
The one in the middle goes to the intake airbox on the right side. The one on the right goes to a purge valve to the right, and the one on the left goes underneath the intake manifold to some other valve, not sure which valve one that is.

Would any of these work to suck-up some seafoam to clean the PCV system?
