Rusty,
Another option would be to buy another engine for spare parts. They
sell low mileage JDM engines for about $1100, and then you'd also have the other
accessories as well, such as water pump, alternator, etc.
I have
a JDM 13BT in my plane, and when I tore it down for the rebuilt, it was in very
good condition. When I measured the wear on the side housings, it was
negligible, and the rotors were also in like new condition with very little
carbon.
FWIW

Greetings,
Well, I've had a busy
day, but the engine is sitting in my garage now. Just from looking in
the exhaust port, I can already see that the major malfunction is
behind door (rotor) #2. There's about 3 ounces of oil in the bottom
of the rotor housing, and the exhaust pipe is similarly coated in oil.
Rotor #1 seems dry, but I doubt it remained unscathed. I plan
to tear the engine down tomorrow, and will post the
results.
My current plan is to
send the rotors to Bruce, to let him get them ceramic coated. I'll
probably also send him the stationary gears so he can press in
new bearings all around. I anticipate needing to have my side
housings replaced, or machined and re-nitrided.
Has anyone got any
particular recommendations for a shop to do the work on the side
housings? New housings are about
$350-$400. Would the machining and re-nitriding cost significantly
less? If so, that may be the way to go, since the porting is already
done.
I'll know more
tomorrow.
Cheers,
Rusty (it's steak and
beer time again)
