Well I recently rebuilt my motor on my 87 na. there where some good threads out there, but I thought there should be another.
The reason for the rebuild was overheating. Pulled the cap and I could be bubbles, and I knew I had a problem. I tried to take a lot of pictures through the process, hopefully this might help someone.I started 3-1-11 and finished 5-1-11. Yes it took a little while but of course there where problems along the way..Well lets get started..pulling the motor.

 

motor is out

 

tearing it apart to see what happened..

rotor housings don't look good either.

o.k. so I will post some more later...

 

I <3 rotary pictures. Thank you for sharing.

 

well thanks to Rotaspinna69 I got a motor. Luckily I had access to a parts washer.

 

Me too, and FC's make me

 

i just rebuilt mine as well.. same issue.. A piece of the front iron chipped off so coolant was getting into the combustion chamber. Ported, and sent housings to goopy to get refurbished. Nice build man keep it up.

 

time to start porting

 

What tool did you use to remove the exhaust sleeve diffuser?

 

I used a plasma cutter and grinder. It took a little while but I think they came out pretty good
