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.

The parts that connect are at the front of the fan housing. Think of it this way... Anything that goes into the fan gets blown through the heat exchangers. Got an oil spill on the topside of the engine? Expect some of that to get sucked in the fan and blown through the heat exchangers and heater hardware. Water and some dust in there? You got mud.
