Cracked head gasket?? or something else.

So i have a 92 civic ex-v.
i've got heat spikes when accelerating, loss of power, loss of coolant, and the coolant in my reservoir only is oily; just flushed the rad itself and it looks fine.
the rad being fine came across as odd to me. i've had a blown gasket on another civic so i know the signs but i just wanna make sure before i start taking things apart.
i dunno if these are early signs of a cracked gasket or not. since i started having sypmtoms i havent pushed the car at all, havent taken her over 3k rpms at all and as such havent had any problems with overheating.
any feedback would be stellar.
thanks ;)
