Greetings,
 
One of the things that's always bothered me about making a PP housing is leakage.  I've heard very experienced folks say that eventually, any PP housing you make will leak, and it's easy for me to imagine that happening.  I don't think I've heard the same thing about factory housings though.  How are the ports installed in the factory PP housing? 
 
The other problem with a conversion is the side ports.  I know people fill these with their favorite epoxy, but I'd worry about that coming loose, and getting into the rotor.  How much would it hurt the PP operation if you just sealed the ports on the outside of the side housings with a plate where the intake would have been?  
 
Cheers,
Rusty
