man noobs these days.
i would do a search, on the matter im sure this has been covered. search your symptom
but if you are getting white smoke and keep having to add coolant. i would say your coolant seals are blown? i have never experienced this first hand, just putting two and two together.
i'm sure someone will chime in

bad inner coolant seals. motor rebuild.

take out the spark plugs and see if they are clean as a whistle. if so, coolant is leaking into the rotor housings and out the exhaust. motor wont last long.

you should get your coolant system pressure tested just to make sure you dont have any outer coolant leaks. if you dont and the pressurized system is dropping pressure, you then know that you have an internal leak.

I had a coolant seal blow on my old rx7. I think you usually get a slightly blueish tint to the exhaust if coolant is being burned up. The exhaust will also smell kind of sweet. Don't drive it if the coolant seals are blown, you will overheat the car and the engine will seize, which is what happened to my first rx7.

Be careful with it. When these engines start having whats know as the "grey smoke condition" they can spontaneously combust rapidly. The car does not even have to be running for this to occur. Search this forum for this subject, many people have lost their lives, houses and garages this way.

My advice is to unhook the battery, don't make any sudden moves around it, and sell it to the first poor sob that is interested.

Good luck.

Buy a good n/a motor and slap it in there. Most people who do Tii swaps will damn near give em away.
