[hypoxia]

I could smell exhaust fumes in the coach this summer, especially with open windows.  I looked at it yesterday and couldn't see anything from the front.  There are very nice thermal blankets covering the exhaust.  Behind the generator is a cover with 4 screws attaching it, once removed there is excellent access.  I lowered the pressure into the generator airbags which dropped the generator a couple of inches.  There was a lot of soot below and under the thermal blankets.  The thermal blankets are held on with safety wire, cut it off to remove the blankets which were filled with soot.  I started the generator and could feel a blast of air coming from the gasket between the turbo & the exhaust flange.  Five nuts are used to squeeze that metal gasket, four were finger tight. When the flange opening was welded to the pipe there was a  burr that kept the gasket from completely squeezing the gasket.  I filed that down and ordered the gasket and nuts from Martin Generator.  My backyardigan winter camping visitor says they always replace the gasket and nuts on turbo exhaust manifolds.
