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.
