D15b7 head gasket !

Hi Guys ,
I have just bought a 1995 civic eg with a d15b7 engine . Just yesterday when I was reversing the car started to vibrate and the exhuast was making sounds kind of like the rotary sound , now white smoke is coming out of the exhuast . Could it be the head gasket ? But there is no oil in the resvoir tank and also the oil is brand new and it dosent have that milk shake texture that every one says a blown head gasket should have ?
Please let me know wat you opinion is ..
