Has anyone routed their pcv to the exhaust instead of up to the intake manifold? Using the exhaust gas flow instead of the manifold vacuum to pull the crankcase vapors. This is for a race car, so emissions isn't an issue. Any insight is appreciated.

 

I have seen this on a domestic v8. It is supposed to give you a negative pressure in the crankcase and provide a tight ring seal. Guy i talked to said it was critical to get the right inlet angle , going into the exhaust, otherwise you might actually pressurize the crankcase. Also I think they don't use a pcv valve with the setup, it is just a breather line with a oil seporator at the valvecover.
