I just took some pics of what your talking about.
The rotor housing here is from an s5 na.
I took out the sleeve.

The sleeve has two small holes, one of them hidden in the picture but on the other side of that one hole.
And the exhaust port has a hole that leads to a chamber in the housing, this hole is hidden under the sleeve, also notice the two small holes under the exhaust port.
Picture of the "chamber":

I guess that "chamber" leads to a passage way in the irons which end up in the avc / lim.
Basically you have hot exhaust gases running through your engine along side the coolant passageways.

Thats not cool.
