Took the sixteen pound cast iron exhaust manifold off the 102,000 mile

1988 motor

I just bought and looked into the exhaust ports. The rotors look clean and

the

seals seem to be free in the slots. When I turn the engine over with
a socket wrench on the front nut I get the three poofs in a row I am

supposed

to get from each rotor. Thanks to Bruce Turentine for that trick.

Next step is to rig some sort of electric motor to turn the engine over
so I can check for three equal compression pulses in the spark plug holes.
If that is OK I will do a pressure leak down test on the cooling system.
If all looks good and it generates at least 180 HP on my cheap dyno test
stand I am going to fly it as is. No overhaul.

It is not like a piston engine where parts fatigue and break.
Nothing EVER breaks in a rotary except the apex seals and then the engine still
does not stop. Even the apex seals don't break if the engine does not detonate. 
You will always get plenty of warning before the engine will no longer
run. Not counting wiring and plumbing failures of course.

This is a big advantage to the rotary in not having things jerking up 
and down, coming to a dead stop and starting up again twice per rev.
Its a wonder to me the silly piston engine lasts as long as it does.
