1983 Mazda Rx7 GSL part 3

That's awesome to see now. I pulled the engine and found that the chrome on the housings was almost gone in a few places... and others had about an inch missing on either side. That smoke was everything... oil, gas, water, coolant. I've since put a 12a street port engine in and it is running strong. Just little things to work on now. Maybe a factory turbo... who knows.

i had sort of the same problem with my 12a but i found out.. that it was the (omp) oil meter pump. it was stuck and was pumping to much oil into the intake to lubricate the seals at a low rpm but my smoky 12a was a little darker in smoke grayish bluish smelled like gas and oil your smoke is just plain white it looks like your burning water? or the vid doesnt show the color of smoke? how old was the gas and did this just happen from one day to the other?

there is only 2 things i can think of that would make your 12a do that and that is 1.either you are burnin really really rich if thats the case then i would have your local shop tune it for you or a rotary shop(best way to go)...and 2.you could be buring coolant(unless your using water) check your seals and every thing that transfers coolant to the engine,look around on the net and find some rotary shops and get there number then call them and ask them what they think it is
