I have a 1972 AZ600 Coupe and whenever I am driving at pretty much
any speed *with the windows open* I can spell exhaust fumes inside
the car. If I drive with the windows closed, I do not smell any fumes
at all even with the fresh air coming through the vents. I just
replaced the exhaust system from just after the heat exchanger all
the way back (new muffler and all) but that did not make any
difference.
Any ideas from all you Coupe owners out there? Do any of you
experience the same thing? I do not remember this being an issue when
I had my first 600 Coupe back in 1976.
Any thoughts are appreciated.
Thanks!

Exhaust fumes
Re: Exhaust fumes
Here are my ideas;
1) You don't smell anything when you close the windows. If you lift up the
boot on the gear shift shaft which is on the floor board, do you smell
exhaust now? If you do, the problem is probably being developed in the
engine compartment.
2) Is your engine clean? If it has an oil leak or has oil on the cylinder
fins, you will smell something.
3) check the gasket connections where the exhaust manifold connects with
the head and the heat exchanger. If you have a mechanic's stethoscope (or
one from a doctor/nurse), you can listen for a leak. And you might want to
check for leaks at all connections along the exhaust system.
4) The original coupe mufflers had a hole in the bottom to let the water in
the exhaust escape. These used to rust to a larger diameter and used to fill
the cavity above the axle with exhaust which you might smell. But you said
you had a new
muffler.
5) You said you can smell exhaust with the window open. Was that with any
window open? If you open only the passenger window, can you smell the
exhaust?
The USA coupes had all the exhaust ported to the left side before being
directed down the center of the vehicle.
Well, those are my ideas for the moment. If you get tired of the exhaust
smell, you can always go down to the hobby shop and buy some glue to sniff.

Re: Exhaust fumes
Thanks for the ideas. I did get a chance to poke around under the
hood and I discovered that I have an oil leak somewhere on the right
side of the engine. I think I have a head gasket that is going. There
is oil on the inside of the fan shroud and some oil pooling on the
right lower side of the engine compartment. The cooling fins have oil
on the front and right sides. I am pretty certain this is the
problem. I need to drop the engine on this in order to get the body
painted so I will have an opportunity to fix it. Any other helpful
suggestions along the lines of oil leaks would be appreciated.
Thanks
