You have coolant leaking into the combustion space. This is will be caused by a leaking intake manifold or Rotor chamber.

On that car, believe it or not, it may be normal. Those early rotary engines used what they called a "sub-zero starting system". There is a bottle under the hood that holds antifreeze, but is not a reservoir bottle. Mazda put a temperature sensor in the oil pan. If the sensor reads less than freezing (or is just disconnected or open for some other reason), A motor is turned on (about the size of a windshield washer motor) that sprays antifreeze into the intake. The coolant helps create a better cold seal between the rotor wipers and the rotor bore so that there is enough compression for the engine to start. I'm not kidding. Really.
Your car has what is called a Wankel or rotary engine. It does now have a cylinder head gasket. It also doesn't have a head, or cylinders.

I have a 1986 RX-7. No, it's not normal for this to happen. You most likely have a head gasket that has a leak or crack. It's likely that you have white smoke coming out of your exhaust system. You may even see antifreeze in the oil pan or on the dipstick (it can either be separate or blended together to make a sort of light brown sludge) . If you have antifreeze in the oil pan, do not operate the car. You may need a rebuild or possibly a new engine and running the car with antifreeze in the oil could totally destroy your entire engine and any chance of a repair.

RX-7's don't have head gaskets (they don't have cylinder heads) and in fact, they don't have cylinders.
Still, like any engine, coolant in the combustion chambers means serious damage. On a rotary that means a new motor because rebuilding these (especially if its a 12A) is a waste of time. You'll need 4-5 donor motors to get enough good parts to rebuild 1.

that is obtrusive that your mom and dad such as you. do not purchase a "7" as a usual vehicle. that is extremely quickly and corners super in case you have THE adventure to deal with IT! it may kill a clean motive force very rapidly. The rear wheel rigidity will artwork in snow if the motive force is elementary with a thank you to apply it acceptable, however the "7" sits low to the floor, it fairly is a topic in deep snow. that may not considering the specific standards for keeping a rotary engine in sturdy subject. that is not a initiate and go vehicle. purchase a Honda or Toyota, and so on. for that. A "7" should be run confusing to final and that's the final element every person might desire to tell a clean motive force to do. toddler a rotary and it will die a speedy and high priced dying. My innovations for a clean motive force are to purchase a low-priced "knock approximately" for a usual vehicle. something with low potential and super crash survival skills. not a overall performance motor vehicle. Get some years and a few formal sportscar dealing with education at the back of you until now you think of a pair of "7". Your community activities vehicle club of usa people would be better than happy to introduce you to the international of overall performance using. they regularly run seminars and courses in the process the racing season. look them up online with a seek for SCCA, Omaha.

i mechanic for a living,and own a shop,,its not at all normal to find coolant there,,you need to check the head gaskets on it,,its either cracked a head or blown a gasket,,or you could have a hair line crack in the cylinder wall,either way its serious and needs to be found and repaired ,you should notice it in the running of if,,it may have a rough idle,,or a slight miss-fire in it when its running,,but id get is checked,,if you drive it,,the anti freeze will ruin the crank shaft in it,it causes the oil to bead up,and it will spin a bearing,,good luck with it hope this help,s.

I used to have a Mazda and to be honest just get rid of it. Mazda's are horrible cars. And to answer the question no it isn't normal.
