Rusty,
I Heard similar stories, but am sure
Lynn is correct in that, if their done correctly their OK. The one's I seen
weren't so good.
The new method of welding to the steel liner,
eliminates any possible leak. I originally suggested welding to the inner and
outer aluminium, but someone suggested that wasn't feasible, as it was too
difficult to get access to.
So Tig welding to the steel liner is good but
you have to use a steel tube - which you can't weld externally. So I came up
with a method of Tig welding a aluminium tube and flange to the exterior, which
has an O ring seal to the steel tube, and passed it by Bill J. who felt it was a
good idea. Probably could use a couple of O rings if you felt like it. The
advantage of this is that the O ring will allow for differing expansion and
contraction rates which might put stress on the inner tig welding. Am elegant
solution IMHO.
On the side ports, your suggestion would be
OK.
Of course the factory PP were integral to the
injection casting.

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
