1986 Mazda RX-7 Smokes rx addict
After setting for some time after use when I start my RX-7 it blows out white bluish smoke for quite some time until the engine is warmed up. Then it runs normally for the rest of the time bellowing out a small amount of smoke when going down the road. As far as I understand this is normal as these cars due use oil. The oil metering pump pumps oil into the rotor housing and when you start the engine some oil is mixed with the fuel because the throttle is attached to it. The car runs fine and seems to have acceleration, plenty of power and short of a small tune up runs quite well. Smoke is my problem and sometimes smokes forever after start up. Is there an eaiser fix for this problem other than replacing the Apex seals and springs, side seals and springs and the center seals along with the springs that would seal the rotor to the rotor housing as it turns. As the car seems to run great coolant may be leaking into the the rotor housing. Not all the time but maybe on start up or shut down the engine. I suspect that the seals are worn but not shot as a compression test would show that I have good, not the best compression 90 PSI. I am not comfortable with the idea of a new engine and am trying to decide how to fix what I got with Minimal cost. So do I do a whole rebuild or temporarily use Lucus Oil. Car is in excellent condition with original interior right down to screw cap covers, orginal spare new struts, shocks tires and all else I pumped into it to make it factory original. Plan on keeping car.
