So now that my engine is appart and cleaned, it is time to start blocking up
the ports that I won't need.  I went to get some epoxy putty, but everying I
found say 200 deg max continuous temp.  JB weld is says 700deg.  JB weld
should work great for the oil injection ports, but not for the EGR passages.

What does everyone recommend to block the EGR passages?

Dave

A steel exhaust manifold flange. The EGR gets into the system from the stock
manifold through two small holes below the exhaust ports in the rotor housings.
You might need to come up with a new gasket for the stock 91 turbo
exhaust manifold you are using Dave. You could also block it with
the intake manifold flange I think. I will have to look into that
some more when we get back from OSH. When are you leaving in the
Cessna 140?

Dave,
Tracy mentioned that he used potter's clay to fill the EGR ports.  I
think that he meant to fill the cavity below the exhaust port that the
EGR gasses enter first after exiting the small hole in the exhaust port.
These cavities are real obvious when looking at a rotor housing because
they are right below the exhaust port and will be really full of carbon.
