Yes, I replace the oil seal o-rings. Yeah, it was smoking when I got it. Very low
compression on one rotor. Replaced parts with Tracy's overhaul kit. Bearings in rotors were not
replace but looked ok and measured fine. New apex seals and side seals.
I didn't replace the metal oil rings on the rotors as they looked fine. How critical are these anyway and what are the symptoms of failure/damage?

Guys,
I need some help on my recent 13B rebuild for my '87 RX7. Thanks
to all previous replies on the crank angle sensor/TDC
settings I was able to get it to crank and run. Now for the
diagnosis of my present problem: Engine starts and idles with a
slight
amount of smoking. As the engine warms up and I increase the RPM
I get a considerable amount of smoke. The smoke does
not smell "sweet" like it is burning coolant but maybe it smells
different in a rotary. Smoke is white not black. With limited
running
I haven't noticed a drop in the coolant or coolant in the oil.
Before I pull the engine and go thru it again I would like to
pinpoint the
problem before teardown. I thought I was careful about the o-
rings. I used Hylomar for the grooves as per Bruce Turrentine's
tape
to keep them in the grooves. Am I getting oil past the oil o-
rings? Other sources or causes for my smoke? Tests I need to run?
Help! Ed, Lynn, Leon or others.
