what do it do?
 
there is a whole bunch of antifreeze in the oil, when i take the oil cap off its all foamy and u can see the bubbels of antifreeze in there, i assume the seals r shot, kind of like a head gasket, time for a new motor?

How does antifreeze get into the oil on a rotary?

Well, I haven't seen coolant bubbles in my oil before, but does your car spew white smoke at start-up? Especially, if the car has been sitting for a couple days? If it does. that mean your coolant seals are gond and you need to get e rebuild.

yeah it smokes like a mofo untill it is warmed up i mean like bad where i cant see anything, lots of smoke on start up, once its warmed up it goes away and it is fine.

A bad outer O-ring at the bottom of the engine, between the engine and pan would do it.

You need to do a leak down/pressure test on the coolant system. Also, is the dipstick in your coolant resevoir tank blackish? Does the exhaust smell sweet when it's smoking? How many miles since rebuild/new?

Also, is it hard to start sometimes? And when it does start, is it very rough and lumpy, with huge clouds of smoke? If so, it's money time (rebuild).
