I noticed that Rockauto, AdvanceAutoparts and Autozone do not have a pcv valve listed for the 2007 Toyota Sienna. Is there no valve, only a straight tube? Is there any part to replace or monitor to help the engine run cleaner like the pcv valve in previous generation Siennas?
No pcv valve on 2007 Sienna?

I can't speak to Toyotas but i own several GM products with no PCV.
They use a metered orifice in the throttle body. I'm sure yours is similar.

Yes, cars are getting easier that way.
I've seen some where the PCV valve is a stub threaded into the top of the block skirt, with a short hose plumbed to the intake manifold (GM Vortec 4.2L I6).
Ecotec 2.2's have no serviceable/visible valve what so ever. It's all ported internally to the intake manifold. I'm not sure if all Ecotecs are that way though.

Toyota lists a pcv valve for the 07 sienna, not sure why it is not listed anywhere else.
The 3MZFE has a PCV valve PN 12204 20060 . Should be located on the top middle of the engine.

The 2GRFE has a PCV valve PN 12204 31040 . Should be located on the right front of the engine.

So does this stub need replacing or cleaned?

I don't recall hearing of anyone needed to service it. If you count out the 6 runners on the plastic intake manifold, it's smack-dab in middle, aiming down, then 90deg to the orifice on the block.
