Bad Coolant Seals
 

Okay, So I'm pretty sure my cooland seals got eaten by the ATF I put in my barn car to get the motor unseized. I see white smoke come out of the exhaust sometimes on start up and she heats up pretty quick at high RPM's. I have been running her around town and have no problems because I keep the RPM's down and she runs just great. I live in a small town and can't find any mechanic that knows rotary's to get the rebuild I need. Is there any problem with runing the car this way if she never over heats?

Perform a cooling system pressure test.

Or with the car stone cold, pull the rad cap and start it up. Look into the coolant filler hole. If you see a steady stream of bubbles, rev the car a little. If the bubbles increase or coolant gushes out, then you probably have a failed coolant seal.
