rebuild...
 

Hi,
I have a 1988 RX7, it overheated cause the radiator malfunctioned. I replaced the radiator and when I started it, there was a ton of white smoke. so I started checking it out and found water in the oil, in fact the oil looked like a milk shake ... I read some post and so I decided to tear down the motor myself. I am at the freeze plugs at the timing chain. Could it be one of the plugs ? or what ? Any help would be great.

No it's most likely a coolant seal. When you tear it down completely you're likely to find the seal that took a dump.

White smoke is usually coolant burning
