Default Heater Stank

I have a 2002 Impreza 2.5 RS. it just ticked over to 250K miles. I've started to notice that when we run the heater is smells like Carbonmonoxide in the cab. Any ideas as to why that would happen? i'm thinking there might be an exhaust leak under the hood and it's being sucked into the cab from the engine bay?

Thanks

Exhaust leak is very likely, does it do it while sitting still, moving, or both?

Easy leak test (since it's cooler out) is to start the car and have a friend hold high idle while you block the exhaust tip. Look under the car for steam escaping to locate a potential exhaust leak.

PS, CO is colorless & odorless.....you are likely smelling the other crap in the exhaust. ;-)
