Robert---A portable Carbon Monoxide Meter, such as the kind for use in
homes, will detect an exhaust leak. As you may know, they're small
enough to get up close to the source, and have a digital readout. You'll
have to use this outdoors, as running the engine in a garage will trip
the meter, regardless.
Short of that, if the exhaust is leaking from a connection, you might
spot it by squirting a dishwashing liquid on it, and follow the bubbles.
Hopefully, you don't have so much blowby that it is getting sucked back
from the vacuum created at the rear of the car. How does your rear
bumper look?
