I need some help with my 88 rx7 I started it as usual the rpm immediately started dropping I gave it throttle to keep it running and clouds of white smoke was billowing out the exhaust I backed out the garage made it to the corner it stopped smoking I went to the store not even a mile away, turned it off came back to the car tried to start it it wouldn't start I had to have it towed home. I haven't had no problems before this any suggestions on what I need to do will be most helpful.

 

check for signs of antifreeze in the combustion chambers.

 

Coolant seals or flooded motor..
