White smoke coolant leak - help
 

Greetings,
My 90 RX7 has a coolant leak. I'm blowing white smoke out the exhaust. I pressurized the cooling system and it doesn't hold pressure. Plugs looks steam-cleaned! However, I see no coolant leaking and can't figure out where it's going.

Having never torn down a rotary I'm not sure where to go to trouble-shoot the problem.

Any suggestions would be greatly appreciated.

Hopefully coolant isnt leaking through a bad seal and entering the combustion chamber. That could be a possibility why coolant isnt leaking. Its a oval seal between the combustion chamber and the chamber where coolant flows to cool off the engine. I remember seeing this happen to a FD in sport compact car.
