Re: '90 Coupe Q. Blue Smoke, Help!

["Pennell, Andrew" <APennel@bsadpo.emba.uvm.edu>]

My parents have a 90 coupe that used to be mine. The crankcase
ventilation valve went bad on it and the oil consumption problem was
apparent. Maybe this is could be the problem. In the case of my car the
oil consumption was accompanied by a bad smell inside the car.
