Edit to make sense :-)

So as I am in the middle of backdating my exhaust system, it was hard not to notice how much oil/grime was in the heating tubes (everything that connects to the exchangers and heater hose under the car).

On each side there is a connection to the fan houseing and I am assuming that that's where the grime comes from. Seems like there should be some kind of filter or something to keep the tubes from getting filled with crap.
At least that's how I felt after spending a day trying to clean 'em out.

rob, anything leaking from the front of the engine (main seal), vapors in the engine bay in general, are going to get pulled in by the impeller fan and shoved into the ducting and he's, recoating everything. a BIG reason to make sure all of the tin seals, oil fill tower seals, spark plug boots, etc, are intact and sealing. if your imp housing was all gunked up prior to the change, and you didn't clean it, you just started pushing the crap into your new hes and clean ducting. if the old system was a mess, the ducting forward of the heat control valves is prob loaded too.
