Hi Paul,

Finally got a 13B and have started tearing it down for overhaul and conversion
to a aircraft.  Probably my LongEz.
I have Bruce Turentine's video.  He suggests a book by Tracy Crook. I have been
reading all the comments on the net for sometime and find them all really
helpful.

Now I need to get that book from Tracy but   do not have his address or 'phone
number. I'm sure you can help.

By the way I was on the verge of asking for one of those O ring set you were to
send for testing.  Didn't know I could tear the engine down so quickly.

Now I need to re-assembly and figure out where to put 'STUFF'.  Any and all help
will
be appreciated.  Perhaps I can even be a help to the group. Retired from NASA 1998.

Fly fast, land slow

Make sure you mark all the seals and springs where they came from if you plan
to reuse them. One seal per baggy with a label should work. If its not too
late. Frequently the seals are OK just stuck in the slots from carbon
and other EGR junk Mazda injects into the combustion chamber.
I don't want to gross you out but that is like eating your own......:-)

I have a engine that was overhauled in 1998. The side and rotor housings
are perfect. The back rotor had no compression because one seal was stuck
in its slot. Pictures in a day or so. Strangely enough only one apex
seal on the back rotor had this problem. Probably the engine sat around 
and oil coked the slot that was at the bottom of the trochoid. That one 
slot is really badly coked up however. 

Blocking off the EGR and mixing two cycle oil with the fuel
should completely solve this problem forever and I would not be a bit
surprised if rotaries had a 4000 hour TBO in aircraft use eventually.  

Synthetic oil in the sump should also help as it has a much higher
breakdown temp than regular motor oil.
