Bob,
  Do you recall the I.D. of the injection tubes you used and were you
running a 12a or 13B ??

I built P Ports by just drilling a hole through the housing, squeeezingin a diesel injection tube, and epoxy fill the entire water chamber it is drilled through. ran that little motor on the street for years and it never leaked.

Greetings,
Â
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?Â
Â
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? Â
Â
Cheers,
Rusty

Rusty,

I have run my PP on the single rotor for about 25hrs throug all sorts of heat cycles and never had a problem with leaking. Keep in mind that my insert is held in place by a flange with two bolts, so the JB only seals, it does not do the holding.
I certainly would never want to depend on JB for holding the insert in place.

On your question with the open side port, one of the side ports was open during the same test period, closed on the outside. Never observed any negative effect, however, it never ran max RPM. The highest was 5000RPM. I have closed that port now for the next test runs.
Â
FWIW.
