Very dangerous.
There is supposed to be a fresh air intake in the cowl. That then leads
either directly to the heat muff (earlier models of 415C) or to a diverter that can
either flow the air through the heat muff or around it (later models of 415C on).
In any case, there should be NO air deliberately routed from the engine
compartment into the cabin. An aircraft with such an arrangment is
unairworthy, illegal, and should be grounded immediately.

----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----I've noticed on my recently acquired Ercoupe that the cabin fresh air intake, intakes directly from the engine compartment. There is no shut off associated with it, although I can pull on cabin heat which gets air from another location, still in the engine compartment. I cannot detect any exhaust leaking but am getting a lot of engine compartment smell, apparently from that source. Is that normal? Am I overlooking something? It tends to leave my clothes smelling slightly like the engine after flying for a while. Thanks....Roger
