Re: Need help with 89 mazda rx7 rotary engine.

Re: Need help with 89 mazda rx7 rotary engine.
hey guys. took this car of mine to a dealership to have a professional to work on it. first thing they did was do a compression test on it. 3 out of the four chambers, cylinders or whatever read about 5.3 compression when the best possible is 7.9 or somthing like that. the 4th chamber read 0(zero) compression. will replacing the rotary seals repair my problem or am i screwed?

there aren't 4 chambers in a 2 rotor engine, there are 6 (3 per rotor). you want to take your car to a rotary specialist, let us know where you live so we can find you someone.

Re: Need help with 89 mazda rx7 rotary engine.
Sounds like it could be a few things actually. If the engine is not idling correctly and you are having to press the accelerator to have it run then it could be the BAC(Bypass Air Control)valve located right below the intake manifold next to the top fuel rail. Disconnect the harness from that and try to crank the car. Could also be bad TPS sensor or MAF(mass airflow) sensor giving bad readouts. Had that issue before.
