Fumey cockpit



Also check all the emissions equipment.  I guess it varies from country to
country, but my Aussie 75TS has the carbon cannister in the boot with the
associated overpressure valve venting into the same space.   I will be
moving it exterior to the cabin space as soon as I  get 'round to it.   I
guess that the emissions stuff has a limited life and bound to give problems
eventually.

Subject: re: Exhaust Question

Gabriel,
My '86 has had exhaust (sometimes gassy) fumes in the cockpit for quite
awhile now and I've tried all the things you have. Put in a new trunk
seal, checked all openings in the trunk area under the mat, the fuel
sender gasket, tightened all the fuel line clamps, checked all the
hoses, the filler inlet hose, and the exhaust components (Stebro from
the cat. back)

But I did find out that my cat. converter had pinholes in it which was
the main source of the smell. To check for leaks in the exhaust system,
I attached the end of my shop vac to the tailpipe and use the vac to
pressurize the exhaust system. Then I ran my hands all around the
exhaust system feeling for an air leak. I tried to weld shut the holes
in the cat, but I just made new holes. (of course my local Alfa mech.
told me that he had never had an Alfa cat. fail but only rust away)
Finally I got a new cat (from DiscountConverter which is another story)
that solved this.

In fact I got no fumes with the top up, all the windows shut and the
ventilation system open to outside air. This will put positive pressure
inside the cockpit. If I were to crack open a window, then the fumes
would return.
