Ok Hi everyone,
I'm new to these things...just got a '80 rx-7. It smokes like the dickens....is this a symptom of worse things to come or can it be remedied without rebuilding the motor??? Runs fine otherwise.

does it stop smoking ever? Like maybe after it warms up. Could be alot of things. Coolant, oil, fuel.

not sure really....but hypothetically lets say its blue...and lets say its black....and that it stops after it warms and that it smokes all the time....give me some situational info...

blue is oil, white is coolant (also smells sweet). Black is probably too rich. If stops after warm up most likely it is oil and it is kind of normal for that to happen in a rotary. If smokes all the time it is most likely a possible bad OMP (oil metering pump) in which case it may be stuck wide open (not really bad, could not be working at all). For coolant it could be a crack in housing and leaking coolant through a water passage, or maybe the o-rings on the intake manifold are **** and leaking coolant into the intake ports. Really, there are alot of different scenarios that it could be. Giving some specifics could really narrow it down quite a bit.
